Effective Bentonite Pond Sealer For large ponds | Lonestar
The working principle of bentonite pond sealer is simple. Sodium bentonite absorbs water, expands, and creates a muddy gel that fills holes, pores, and cracks in the soil. In ponds with water, you can sprinkle the sealant over the water surface, it will sink to the bottom and create the muddy gel layer on top of the pond floor.
