Pond Boss Forums POND CONSTRUCTION Soil questions Sealing Alternatives - DB 110- DB200- ESS-13

I recently used db200 as an additive to my ponds. The builder did not compact the soil well enough so I pulled out the rip rap and relaid the clay. My clay or clayey soil is okay for ponds so I decided to add the db200 as an extra help.

Since the builder had already laid rip rap over the entire pond bottom and banks, we removed as much as possible but felt going with a 2 layer approach would work best.

The fishing pond is 1 acre so I put down a layer of db200 (four 40 lbs pails) which is on the high end of application but I do not want or did not want to have to do this again. We added layers of clay about a foot and rolled the layers then added 2 more pails of db200 and rolled again. I did this to the swimming pond and the forage ponds. Nothing but a liner is 100% but so far the ponds are doing well. The total cost for the db200 was $3000 but I used that to seal the fishing pond, swimming pond, forage pond and 2 frog ponds, about 2.25 acres total.

I did use a sheepsfoot and flatshell roller which is critical to sealing.

My ponds sit on top of the hill so very little watershed. Ponds rely on well water so I wanted to minimized lose if possible. So far very pleased with results.
