Pond Boss Forums POND CONSTRUCTION Soil questions Another leaking pond question - sandstone bedrock

Welcome aboard-- glad you found us-- you will love this place.
Fractured sandstone will not hold water. It will look good but will usually leak.
You are sure on the right path--get some bentonite and put it out like you are planning.
If you are not treating a very big area put as much bentonite or clay out as you can afford.
8 pounds per foot is not any more work to put out than 2 pounds.

I have filled in holes with everything sacrete, bentonite, pond seal. The roots may continue to be a problem but before you get the heave equipment out try the patch.

Thanks for posting---Send pictures ---let us know how it is going.
