Can anyone tell me if there’s anything I can add to my pond bottom take make it harder? It’s currently just muck that you sink 6-12” into with every step (see attached pic). The pond builder packed a 2” solid layer on bentonite down, then packed 12” of native soil (consistency of powder) on top of the bentonite. So far, the pond edge, submerged and not, has claimed a boot and a croc, the crock still in the mud beneath the water. Would adding gravel, or pea gravel, to it compromise the bentonite layer if it just sinks through the mud, or…. ?
