Agiculture lime or Lime Stone Dust Question for base for above Ground Question

[Ilovepools4545]

Hi used Agricultural lime or Lime Stone Dust for above ground pool pasted and compacted and wetted as I compacted it.

After installing the pool the lime stone dust as turned to soup. I am very frustrated because it was recommended this and now I can literately put my foot in it like a puddle of water. I am guessing perhaps the water is not draining out of my perimeter the opposite water is draining out and taking the base material way. Under the Base is partial clay, limestone driveway gravel, then limestone dust. have not seen any base material at my end of my drains so I think water is flooding in and just messing it all up.

Any thoughts on why this is happening, when this was suppose to be a great base?

I would appreciate anyone input on why this stuff had turned to soup?


Thank you

We used aglime and it has been excellent. I suspect the problem is water, not the base you used. Make the water drain away from the pool.

In your previous post with the picture of the are where you put the pool you knew that you have water run-off issues and were leaning towards putting down a concrete slab because of it.

Was the crushed stone properly and fully compacted in lifts no greater than 2-4 inches at a time?

Did you put any sort of curtain drain to remove the water from behind your retaining wall? It wouldn't really matter what kind of fill you put behind that wall if there is no way for the water to get out from behind the wall you will turn your fill into quicksand. The clay layer you have under the fill while it can be very stable to build on it is also pretty much "waterproof" and it won't let the water drain down further into the earth.

Crushed stone is a great base and is really the only good choice if you are forced to fill an area under a pool rather than dig it down to level.

Thanks for staying with me and answering my question.. I did not go with the concrete because I thought it would eventually fall of level and I would be stuck with a tilted slab. Instead ofa curtain down but the I have design this to allow water to drain out one bottom side, in addition I have two top has drain catch to catch the surface water. To built up to level with rip rap, then 52 drive gravel, and finished with limestone dust that was wetted and compacted every 2 inches.

I am having a hard time to understand limestone dust is used, I can't see how anyone can keep this dust protected from rain water back. Do you put anything over your limestone and can it handle any water such as normal rain water or does it need to be covered with river rock or something else. thanks for your help. David
