Xadoman ★★★★☆ (1035)	It works pretty good. This is just course sand that is used to make concrete. People used to put it in sandboxes for their kids. They just use common sand. I am going to use a sand that is specially sieved for concrete. Don't use geotextile in drains. That stuff is for roadbeds. Gravel by itself is also another good backfill. As much as I have read from eng-tips forum, the drainage pipe and gravel surrounding it needs to be completely wrapped into the geotextile. Otherwise the system gets clogged very quickly. The beauty of the concrete sand is that it does not even need the geotextile and that is why I will use it around the drainage pipe.

They are not animals. Xadoman wrote: Natural lakes can not be drained. All natural lakes have a source and drain. Xadoman wrote: The only solution to save the natural lake from turning to swamp and losing its open water surface are is to pump mud out of it. Nope. Most lakes don't need pumping out at all. They don't gather mud. Xadoman wrote: It is expensive as hell but occasionally they have done it because they want to preserve some beautiful lakes where people can go swimming or fishing. Water flow does that. If you try to turn a swamp into an open lake, like what happened to your lake, nature will simply return to swamp over time. Xadoman wrote: Nature always wants to take over lakes and turn them into swamp. WRONG. Compositional error fallacy. Careful with this one, it is the same fallacy behind bigotry and racism. Xadoman wrote: Here is for example a project I found from web to save a lake from turning to swamp: ...deleted Holy Link... One instance is not every instance. Extending one instance across all instances is a compositional error fallacy. When you do that with people as the class (instead of lakes), the fallacy is called 'bigotry'. When the property being extended is a genetic trait, that is called 'racism'. You are doing it with lakes as the class and algae and sediment as the properties. * Not all lakes have sediment build up. * Lakes are part of a river or creek flow. They all have sources and drains. * Lakes have no age. They either exist because of a place where water is flowing is crossing a basin, or not. * Just because you have never seen a swamp dredged into open water doesn't mean it has never happened. * Standing water less than 30 ft deep is generally a swamp. It still has a source and a drain, like any lake. It may be seasonal, but they are there. I have no idea why you brought up septic systems at all. You condemn them in favor of your fancy outhouse pit. It is still an outhouse pit, even you line it with concrete.

Lakes have no age. Xadoman wrote: People had no technology to dredge a lake back in a day. Yes they did. Dredging is as old as ancient Egypt. Steam shovels have been around since before the War of Secession (what most people call the Civil War). Xadoman wrote: Pretty easy to do, actually, especially if it was done a long time ago before they required permits for that stuff. What kind of technology are you talking about?

Xadoman wrote: For example trees on the shore of the lake are aproximately 200-300 years old. So? What has that got to do with anything? Xadoman wrote: I bet it was! Compared to a septic system installation it was not so bad. So you've said. A properly installed septic system does not put runoff into the lake. An improperly installed septic system stinks and backs up. Xadoman wrote: I would say it turns out cheaper in the long run. Think so? You've sure put a lot of money into the thing. Xadoman wrote: Leach fields get clogged as years go by and they need to renew them. Nope. They don't clog unless they are improperly installed or damaged in some way. Xadoman wrote: They also need to empty the septic approximately once in a year and it also costs some money. The tank does not need to be emptied annually. For a single person on a 1000 gal tank, once every 10 years is quite sufficient. The cost is around $200. Xadoman wrote: Over the years it adds up. $200 in ten years is CHEAP. Xadoman wrote: My solution has no such expenses other than my own time to empty a pit full of composted manure once in a decade. So you want to shovel your own shit, and put it on your yard, where it can wash into the lake you are trying to protect. Xadoman wrote: Wasn't expensive enough for ya, huh? I went for the longevity for the structure. Whatever. I consider it a monument to backward thinking. Xadoman wrote: I read from eng-tips forum that common iron will rust pretty quickly in concrete. Not really, unless it's improperly installed. Most reinforced concrete uses rebar of common iron. It's not been a problem, unless it was improperly installed. Xadoman wrote: If it rusts then it expands 4 times in volume and works as a hydralic jack and causes the concrete to spall from the structure. Then the mix was wrong, laid wrong, or the rebar was improperly installed. Xadoman wrote: It all depends on conditions but it could happen as fast as 30 years from construction. Improperly installing rebar and concrete shows damage in as little as a few months, or it can take a couple of decades to form. Houses built 100 years ago with common iron rebar are still standing today on those footings and walls. Xadoman wrote: Typically 50 years is considered useful life for concrete structures with common iron. Nope. Over 100 years. Literally, the building itself will fall down from lack of maintenance and weathering before the concrete fails. Xadoman wrote: Feces and urine in the pit will cause much quicker corrosion of the iron Nope. Neither should be touching rebar unless it is properly installed. Xadoman wrote: and that is why I went for fiberglass and stainless steel rebar. It's your wallet. Xadoman wrote: Considering all of this the cost of stainless steel rebar aint nuthing but a peanut in the long run. It's an expensive peanut! Xadoman wrote: Subsidizing is irrelevant. The money they get is irrelevant to your topic. Just wanted to point out that they will plow anything they can nowadays because of the free money they get for the hectar. You can't plow a lake. You can't plow a swamp. It's still a swamp. Xadoman wrote: They would plow the swamp if they could. You can't plow a swamp. Plowing water doesn't work. Xadoman wrote: Fields beside lakes are plowed and those are getting 3-4 times fertilized during the growing season. No wonder some of the fertilizers reach to the lake. Careless farmers are the problem, not the fertilizer. They are allowing their soil to erode. Their crop yield is also suffering as a result.

Either course sand (concrete sand) or gravel will work. Pea gravel is often used here, but larger stones are better (use round stone...it won't compact). Round stone is the best stuff for building a French drain. Yes...something as large as an inch or two. Aggregate suppliers sometimes call this 'cobble'. If you use Geotex, do not wrap the pipe with it! That's a BAD idea. Use it instead to keep the stones from migrating into the surrounding soil, if you use it at all. Just put it into the trench, put the pipe in the trench, then cover it with round stone, then top soil. Otherwise, put some stone in the trench, lay the pipe, and backfill with stone. Make sure you get your slope right when laying drains. What you want is voids around the pipe. Course sand (washed sand to remove the silt), or concrete sand, does create voids, but it also migrates away into the surrounding soil a lot easier. And, of course, you need somewhere to drain it to.

Xadoman ★★★★☆ (1035)	So you've said. A properly installed septic system does not put runoff into the lake. An improperly installed septic system stinks and backs up. I was talking about the cost of building. It was not so bad compared to septic system installation cost. Think so? You've sure put a lot of money into the thing. Compared to properly installed septic system it is still cheap. Nope. They don't clog unless they are improperly installed or damaged in some way. Not sure about that one. Most septic producers mention that the leach field needs renewing after 10-15 years. The limestone gravel literally simply melts away during those years. People are not willing to use granite gravel because it is much much more expensive. So you want to shovel your own shit, and put it on your yard, where it can wash into the lake you are trying to protect. After 10 years of composting the feces will turn into soil like manure. It does not smell or stink. It can be spread with bare hands without any discomfort. Not really, unless it's improperly installed. Most reinforced concrete uses rebar of common iron. It's not been a problem, unless it was improperly installed. Rust is basically the biggest problem with reinforced concrete. It costs billions for taxpayers in a year to repair bridges, roads etc. Without rebar a concrete building could last even thousands of years( in good climate). With rebar the useful life is considered 50-100 years. Stainless steel could extend it to 300 or even 1000 years but even stainless steel rusts eventually in the concrete. Then the mix was wrong, laid wrong, or the rebar was improperly installed. Iron rebar starts to rust in the moment it is produced. It is inevitable. They have tried to protect iron rebar with epoxy coating but in practice those bars did not perform much better than common iron. The problem with epoxy coating is installation - if you cut or nick it you have to coat it over with epoxy again but in practice it is very hard to spot every single little nick. Houses built 100 years ago with common iron rebar are still standing today on those footings and walls. Famous last words - it has stood like this for 100 years and it will ...oops. Nope. Neither should be touching rebar unless it is properly installed. Salt water corrodes iron in the concrete very quickly. Good example is Progreso pier that was built in 1940 and they used aisi 304 stainless steel rebar. It still stands today. The other pier from carbon steel was built in 1969 and it melt away in 10 years. https://www.researchgate.net/figure/Progreso-Pier-Mexico-the-pier-in-the-background-was-constructed-in-1940-and-used_fig1_301279143 I would go so far as to suggest that this forum is full of misinformation. Those guys build bridges and skyscrapers. NO! Do not use Geotex on drains! EVER! I will not because I will use concrete sand. Geotex will clog drains! It is not used for drains. It is used for roadbeds. That is its only use! Most people use it . They use gravel though. I myself am not a fan of some kind of textile in the ground so that is why I look for solutions that work without it. Concrete sand has been used without geotextile and supposedly it works good.

Xadoman ★★★★☆ (1035)	I have no idea why you brought up septic systems at all. You condemn them in favor of your fancy outhouse pit. It is still an outhouse pit, even you line it with concrete. I was a little bit concerned about their safety. I have a simple dug well that is only 8-10 meters deep. I am concerned about the water quality. All the other guys with septics have really deep borewells. It seems they instinctively dismiss the idea of a simple dug well near a septic system. I do not have anything against septic systems if they are properly installed. If I were to live all year round in my summer house then I would install a septic system( I would design it to be fool proof).But for now I only use it for summer time. I do not even have water in my house because I do not like the trouble of emptying the pipes for winter to not to let them burst due to freezing cold( I do not heat the house during the winter because I do not live there ). I like the idea that I can left the house and do not need to worry about pipes, septics etc etc that need protection from freezing. I can go to travel in the winter and forget about pipes under ground. My two chamber composting toilet on the other hand should be completely fool and bulletproof. I can not think a way how it could fail miserably. Bottom slab and walls( 30 cm or about 1 foot thick) are monolithically poured concrete with stainless steel and glass fiber rebar. It should last at least 100 years without much trouble. I will be long gone before it fails.

This is where a greenhouse would work wonders. The odor released is most likely methane. From what I just saw, 60% methane and 40% CO2. https://thekidshouldseethis.com/post/transforming-human-poop-into-eco-friendly-fertilizer This is so funny because until the 1970's my grandmother in Kentucky had an outhouse.

Xadoman ★★★★☆ (1035)	It seems that if you let it compost for about 6 months, you'll have some really good fertilizer for free. I have been doing a lot of research about composting in the web. Turns out that some parasite eggs are really stubborn to die off. It could take even 5 years to completely die. Most agree that 2 years of composting would be optimal. Btw most of us have some internal parasites. It is perfectly natural to have some internal parasites. Also notice how in the video the manure was spread by hand without any discomfort. And that is only after 6 month of composting. That is the beauty of composting - no more smelly flowing liquidy shit that makes you puke when you have to pump or dispose it to another place from your overflowing pit. This is so funny because until the 1970's my grandmother in Kentucky had an outhouse. The topsoil was minimal to say the least. And to preserve our farmlands, in the future it could become the norm. Yes, topsoil is going to be one of the biggest problem in agriculture in coming years. Nutrient cycle is not complete because human feces are mostly dumped to landfills using geotextile as giant diapers to separate them from surrounding soil. Those "diapers" will of course leak and pollute ground water. Those feces should be composted and spread back to fields instead. Modern farming is very intensive. One day they harvest and second day they already plow the field. The land has no time to breath and relax. There is a constant pressure to get the most out of it. I am not sure about the sustainability of such behaviour. Historically most giant civilizations have collapsed because of the soil degradation. Nowadays we have the technology to restore soil. I expect that in the future dredging the lakes and harvesting mud from the bottom of the lakes becomes one of the solution to the problem. I live near a lake and I have thought about building a mud pump to harvest mud and pump it to my land to increase soil thickness( I grow strawberries, very low scale, on about 1 hectar overall). The problem is that during the harvesting nutrients from the mud could get into the lake water and cause the blooming of the algae. That is why they separate the place they harvest mud from the lake with a special geotextile that stops nutrient from spreading out of the blocked area. Edited on 13-08-2020 11:18

You want to click on the 'img' tab (image). The image, has to be web based, where you have an address to link to. It has to end in '.jpg', or some other image format.

I was talking about the cost of building. It was not so bad compared to septic system installation cost. Installing a septic system is not that expensive. All you really need in most cases is a backhoe. The a 1000 gal tank from Norwesco is about $1000. Any modest sized truck or trailer can hall the thing and you just roll it nto the pit so it falls in with the manhole covers facing up. The rest is simple trenching.

Septic systems don't require protection from freezing. If you do not heat your house in the winter, you should drain your pipes. That can sometimes be done at one of the main valves particularly on new installations. These ports are required in the code now. The way they work is you shut the valve, open the port, and run the water out of the taps, particularly the lowest tap. Be sure your water heater is shut off before you do this! You should also drain your water heater. That'll help clean the sediment out of the tank anyway. Just attach a hose leading to a convenient drain point and open the valve on the tank (after shutting it off first!). To restart your plumbing when you use it for the summer, just close the port, turn on the main, and let both hot and cold water flow until all air burping is done, then light or start your hot water heater.

I have been doing a lot of research about composting in the web. Turns out that some parasite eggs are really stubborn to die off. It could take even 5 years to completely die. Most agree that 2 years of composting would be optimal. Btw most of us have some internal parasites. It is perfectly natural to have some internal parasites. Also notice how in the video the manure was spread by hand without any discomfort. And that is only after 6 month of composting. That is the beauty of composting - no more smelly flowing liquidy shit that makes you puke when you have to pump or dispose it to another place from your overflowing pit. This is so funny because until the 1970's my grandmother in Kentucky had an outhouse. The topsoil was minimal to say the least. And to preserve our farmlands, in the future it could become the norm. Yes, topsoil is going to be one of the biggest problem in agriculture in coming years. Nutrient cycle is not complete because human feces are mostly dumped to landfills using geotextile as giant diapers to separate them from surrounding soil. Those "diapers" will of course leak and pollute ground water. Those feces should be composted and spread back to fields instead. Modern farming is very intensive. One day they harvest and second day they already plow the field. The land has no time to breath and relax. There is a constant pressure to get the most out of it. I am not sure about the sustainability of such behaviour. Historically most giant civilizations have collapsed because of the soil degradation. Nowadays we have the technology to restore soil. I expect that in the future dredging the lakes and harvesting mud from the bottom of the lakes becomes one of the solution to the problem. I live near a lake and I have thought about building a mud pump to harvest mud and pump it to my land to increase soil thickness( I grow strawberries, very low scale, on about 1 hectar overall). The problem is that during the harvesting nutrients from the mud could get into the lake water and cause the blooming of the algae. That is why they separate the place they harvest mud from the lake with a special geotextile that stops nutrient from spreading out of the blocked area. Landfills do not accept human feces.

HarveyH55★★★★★ (5197)	Isn't the leach field there to handle the water that overflows from the septic tank? For a home, it really shouldn't be a huge volume, daily. Consider that it's not just toilet water, but water from every drain in the house. The septic tank is there to breakdown the solids, for which only a small portion eventually settles to the bottom, as sludge. Solid waste, is only a small portion of what goes into the septic system, it's mostly water going in, and coming out. It's not concentrated raw sewage or anything else. It all gets highly diluted, before it even hits the drain field. Like a lot of things, some people only focus on the worst possible element, and ignore the obvious, that mitigates much of their perceived crisis.

Xadoman ★★★★☆ (1035)	Gravel is rock, not limestone. Maybe you are referring to recycled concrete, the closest thing to 'limestone gravel'. Gravel is crushed rock. If you cruch limestone then you get limestone gravel. If you crush granite then you get granite gravel. This is how a limestone gravel looks like: This is how a granit gravel looks like: 99% of people here use limestone gravel because of the price. We have a lot of limestone here that is near the surface of the land and not much granite other than fieldstones. The granite is too deep inside the earth- shortest way to granite is about 130-150 meters deep in the ground. Most of it is 600-800 meters deep in the ground. That is the reason we do not produce our own granite gravel. We have to import it from other countries or crush fieldstones. Limestone is obviously not as strong as granite. That is due to wear and tear from vehicles, not rust. Biggest influence is caused by the salt that is used to melt ice. The corrosion of common iron comes very quickly( everything is relative but to me 30 years seems to short) because of the salt. That is why many parking houses have collapsed- there is not much wear and tear from vehicles due to low speed but they bring the salt from the roads and it causes accelerated corrosion of the rebar in the concrete. It won't last at all. Concrete has horrible tensile strength. Not a problem if you make the structure to be in compression. Colosseum and Pantheon are still standing. Those are nearly 2000 years old. There are older buildings than that with rebar. Iron rebar. It largely depends on conditions . Reinforced concrete in the salt water could melt away in a decade. A block of reinforced concrete in a heated room with low humidity could lasts hundreds of years. The corrosion of the rebar in the concrete however is inevitable. Initially the high alkanity of concrete protects the rebar from rusting but the carbonation process of the concrete brings down the alkanity of the concrete and eventually it reaches to a treshold at which the rebars starts to corrode quickly. So those 100+ years structures might be ticking time bombs. This is why they are looking for other solutions. Epoxy, galvanizing, fiberglass, stainless steel, sacrifical anode etc etc. They are using more and more stainless steel in critical areas( for example bridge or road deck) than before because of it. Renovating a bridge deck regularly is expensive as hell and stainless steel in critical areas is cost effective in the long run. You won't be alive that long. What do you care? I have seen concrete fence posts , stairways and other structures failed in relatively short time - 20-30 years from construction. The iron in those structures has expanded and spalled the concrete. I myself would not want to deal with this kind of failure so I simply used materials that would not corrode as quickly (or not at all ) as common carbon iron. There are also other positive sides - with stainless steel the concrete cover does not have to be as thick as with carbon iron and compacting the concrete and the overall quality of placing the concrete is not as critical as with carbon iron. Also the quality of the concrete could be not as good as with common iron. As you can see the using of stainless steel allows much much more sloppy workmanship but still the structure will outlast the carbon iron reinforced structure many times. It is more forgiving for guys like me who are not professional builders. I have my doubts. I think you are going to get a lot of sand in your pipe and it will clog, especially if you use the slitted pipe. And how come your solution with cobble does not allow clogging of the pipe? Water will carry particles from the soil and it will eventually clog the pipe and the voids between the cobble. Concrete sand on the other hand works as a natural filter. It will not migrate into the pipe because ( if the slits in the pipe are right size) bigger grains will eventually bridge the holes in the pipe allowing some water through but not more sand anymore. With cobble or gravel they wrap the whole thing( a piple and gravel around it ) into a geotextile to stop clogging the system. Edited on 14-08-2020 11:16

The leach field is more than just a drain though. The bacteria naturally found in soil also breakdown waste. They work best as the water drains through the soil in the leach field. After 20 inches or so, in a normally functioning system installed according to the engineer's design, the water beyond that point is essentially potable. Wells must be dug at least 100 ft from a leach field, however. Anything like a lake or river must also be at least 100 ft away. Sometimes that is expanded to 200 ft, depending on the State, county, and property. The well is always 100 ft minimum distance.

HarveyH55★★★★★ (5197)	So, basically, this whole thing, might get used a few months out of the year. Then basically sit around unused, most of the time. How much lake polluting could you possibly do, in a few months? Even if you went with the classic, traditional hole dug outhouse, you'd still have virtually no impact on the environment. You just aren't going to generate the volume. The environment is very forgiving, the ecosystem adapts. Limestone takes a long time to erode, if there are no chemical agents involve. Rain water takes centuries to make much of an impact. Over-engineering stuff, is often worse, than the simple solution...

Xadoman ★★★★☆ (1035)	Yes it is. You can even pour it and have it cure underwater. The point was that concrete lets water through it. Only if it's badly poured or maintained. All concrete cracks. It is inevitable. It's also weaker than common rebar. It's advantage is that it's light. It is quite a bit stronger in tension than iron. 8 mm diameter fiberglass is approximately the same in tension as 12 mm iron. Nope. The rebar is not exposed to water or air. Deny as much as you want but the reality is that 1 out of 3 bridges in US is structurally deficient mostly because of rust. Nope. Just a shitty pour. Rebar is not exposed to salt water. The type of rebar does not determine the concrete. With Progreso pier the workmanship was quite sloppy and at some places the rebar is even exposed to the sea water. It is still in bussiness unlike the other parallel pier that melt away in a decade and was made with carbon iron. The one on the backround was made 1940 and they used stainless steel aisi 304. The ruins on the front are from the pier that was built in 1969 with common steel rebar and it simply melt away in a decade. Premix starts curing pretty fast, since it's been sitting in the truck on the way to your site. Yes, I was in trouble with smoothing the top at the end because it cured so fast. WRONG. Both buildings have tensile and sheer loads. And use no iron reinforcement . We have many barns here constructed of splitted fieldstone( granite) and those are over 100 years old and stay strong. They have no rebar inside their walls. Those buildings 100+ years old you talk about probably also have no iron in their footings and walls. You can build foundation wall out of concrete and use no iron in at all. It is allowed by the code. The walls simply needs to be thick enough to counteract the lateral pressure of the soil if you want a basement. Yes it does. No it does not. The dam itself has no iron rebar in it. It is an arc that is in copression. The adjacent towers have iron reinforcement but the dam that holds the water does not. NO. YOU DO NOT WRAP PIPE IN Geotex! Ever! I am talking about the whose system - pipe with cobble should be wrapped into the geotextile. The geotextile should be around the cobble and sealed in every direction( wrapped around the cobble). The pipe is inside the coble and should not be wrapped because the cobble is already wrapped with geotextile. That's right. Use round gravel, 1 to 2 inch in size. This will not stop silt( clay fines) from migrating to the voids of the gravel and clog it. Or do you want to say that the silt flows away with the water? Very true! Over engineering often causes expensive failures. Keep It Simple Stupid (KISS). I did not overengineer anything with my composting toilet. Dimensions of the slab and walls are bare minimum.

Without the foundation the wood also rots quite quickly and the whole thing starts to sag. Then you need to rise it , put some stones under the corner etc etc. I needed a solution that would fix all of those problem. Are those simple digged holes even allowed by the code nowadays? I was worried about the lake because the blooming of the algae. There are some whose leach field pipes are very close to the lake. The water has bloomed 2 times in this year. Last time it took 3 weeks for a water to clear up. I suspect most of the problem is caused by the fertilizers that farmers put on their fields and rainwater washes some of it into the lake. Modern chemicals that are drained into the sewage could cause accelerated erosion of the limestone. Some people have reported problems with their septic systems because of the clogging of the leach field.

The type of rebar does not determine the concrete. With Progreso pier the workmanship was quite sloppy and at some places the rebar is even exposed to the sea water. It is still in bussiness unlike the other parallel pier that melt away in a decade and was made with carbon iron. The one on the backround was made 1940 and they used stainless steel aisi 304. The ruins on the front are from the pier that was built in 1969 with common steel rebar and it simply melt away in a decade. Redirection (pivot) fallacy. Spam.

Xadoman ★★★★☆ (1035)	ITN, no rebar in ancient ctructures. No rebar also in the Hoover dam. There are metal pipes from cooling of the blocks but those are not acting as rebar. Every concrete cracks. Without special additives concrete does not stop water. No rebar needed if building a foundation( allowed by code). Concrete has tensile strength. Rubble does not stop fines from migrating into the voids. Sand is better filter than rubble. Dry composting closet is allowed by the code almost everywhere, also in places where septics are not allowed. Dry closet is the "greenest". The cost of the dry closet is peanut compared to properly installed septic system. BTW, I just read that the embedded cooling pipes in the dam got grouted somehow after. I think it was a bad idea. If those pipes are eventually going to rust and expand then they will crack the concrete. If they had let them ungrouted then expanding iron would have a room to expand. So those embedded pipes are going to be the achilleus heal of the Hoover dam. Edited on 17-08-2020 00:40

Xadoman ★★★★☆ (1035)	The Progreso Pier is also the first concrete structure in the world built with nickel-containing stainless steel reinforcement. Despite the relatively poor grade of concrete used, the pier has withstood the harsh marine environment and has been in continuous service for over 70 years without any major repair or routine maintenance activities. On the contrary, a with neighboring pier located just 200 meters to the west of the Progreso Pier is heavily deteriorated with columns and the superstructure almost entirely gone, despite being twenty years younger. The newer pier was built with carbon steel rebar. One of the reasons why this design was selected was to eliminate conventional carbon steel rein-orcing bars (rebar) by using massiveconcrete in the substructure. TheMexican authorities wanted to build this pier having low or no corrosion risk, thus avoiding the severe corrosion problems that had developed inseveral other marine structures in Mexico. This innovative project utilized type 304 stainless steel (SS) (UNSS30400) for girder reinforcement and,in the long term, for corrosion protection. To do so, 220 tons (199,584 kg)of 30-mm-diameter SS, nondeformedbars were used. The pier shows no visible sign of deterioration after 60 years of service even though the structure has received no maintenance during this period of time, according to port authorities. Of the 146 arches, ~100 were visually inspected and few cracks were observed. Only six arches presented 3-mm-wide cracks. A total of 15 arches presented narrow cracks, with crackwidths in the range of 0.1 to 1.0 mm. As the arches were made of massive,nonreinforced concrete, there is norisk of metal corrosion. A detailed inspection of the damage in the near fu-ure was recommended, however. No corrosion stains or corrosion-induced cracks were observed in theentire pier and wharf substructure.Only a few damaged girders at the wharf showed exposed SS bars—probably caused by ship impact—besides the exposed steel observed in girder #9. Low quality porous concrete, nonreinforced arches and harsh environment. But still in business without major overhauls. Pretty good I must say. Makes me feel comfortable with my own little project.

Xadoman ★★★★☆ (1035)	No argument presented. Argument is presented. Major success using first time in history stainless steel rebar!. No major overhauls or even small overhauls needed in 80 years. Still standing despite low quality porous concrete, harsh marine environment , exposed rebar to seawater because of ship impacts etc etc. 20 years younger parallel pier made with carbon steel rebar melt away many decades ago. Considering all this the price of stainless steel is a peanut. Overhauls that are needed with carbon steel on the other hand are very costly. I myself am not going to use carbon steel rebar anymore. Things have changed. Prices have gone down. In Finland( closest I could get it) there are many stainless steel rebar producers, I am going to contact them when I need to pour another project. The main point in conclusion is - carbon steel will not forgive if you make some mistakes during the construction. You need expensive repairs in your life time. Stainless steel however will forgive a lot and most probably you do not have to touch the structure again in your lifetime. Edited on 17-08-2020 23:55

Rust, is oxidation. Iron needs to be exposed to open air (oxygen), or an oxidation agent. The rust forms a protective layer, and needs to be removed, to expose fresh iron, to be oxidized. I remember a few neighborhood driveway pours, where the rebar was rusty, sometimes kind of nasty looking. Sometimes the weather doesn't cooperate around here, takes weeks occasionally, to complete an outdoor project. 20 or more years later, those driveways still appear to be in great shape. We get a whole lot of rain at times, here in Florida.

Xadoman ★★★★☆ (1035)	Harvey, urine consist salt. Every time you pee you throw away approximately a teaspoon of salt. It causes accelerated aging of rebar in concrete. That is why by the code there are higher requirements for the concrete in sewage pits etc. Also, you can look up for the carbonation process and how chlorides from deicing salts or from sea water ( or from urine) will attack rebar in the concrete. Google "concrete cancer" and you see many pictures of spalled concrete and rusted rebar. I have seen many prematurely failed projects here. Spalling concrete from fence postes, outdoor door steps, foundations , walls, suspended slabs etc etc. If I build something then I do not want to deal with it in my lifetime again. This is why I tend to use foolproof materials although those are a little bit costier than common materials. In the big picture the cost of those materials is a peanut. Just imagine a case you need to pour a slab or suspended slab. You need some "chairs" made of plastic or smth to rise the rebar from the ground or from the formworks. This place becomes an achilleus heal for the slab because the bond between the chair and concrete will never be the same as with pure concrete. The concrete cover in this spot is compromised and the rust nest will form which eventually causes spalling of the concrete. Stainless will probably forgive you that for at least a 100 years or more. I will be gone if such failure in the future will emerge. Fiberglass does not rust but it has its own problems. I could not get angles for the corners from the dealer. They only sell straight rebar. It is not possible to bend fiberglass on your own. The producer of the fiberglass has those anges in stock but our dealer here does not want to stockpile those even though I called them and asked about it many times. Although fiberglass is significantly stronger in tension than iron, it is not ductile and has low shear strength. That is why they do not use it in suspended slabs. Also fiberglass will loose its strength quickly in the case of fire. Edited on 18-08-2020 09:26

HarveyH55★★★★★ (5197)	We don't 'pee' table salt (Sodium Chloride). A 'salt' is simply a molecule consisting a metal atom + gas atom. Rust, Iron Oxide is a salt, lot of variations too, 17 oxides of iron, if I remember correctly. Still think you are over doing this. It's a summer home, which you might use a few months out of the year. You never mention how many hundreds of other people would be using it as well. Mostly, I just see this for you, and maybe a couple other adults. I just don't see a significant volume of waste, that would leach in to the lake, generate by a single family dwelling. If it's a rental, 'party house', where there are dozens of people using the facilities, often... It's a big lake, what little contribute, is basically nothing, compared with the fish, and other wildlife. That RV park on the other side of the lake, probably has more people purging their sewage tank, directly in the lake in a day, than you would contribute in 5 years...
