We have an old pond on our property that we cleaned up last spring. Even though we used a layer of clay there's one sandy spot that is leaking. Can we use polymer while it's dry?
Yes, using the stuff that TJ has, incorporate it in the top 6" of the soil. How big of an area is it?
Fill from an outside water source, (well, surface run off, etc. ) don't rely on ground water to fill it. Ground water coming in through that area will push it out and the pond won't seal.
Where in Indiana?
