Pond sealing bentonite is a natural sodium bentonite clay used to create waterproof barriers in ponds, lakes, canals, waste pits, lagoons, and earthen water reservoirs. It swells many times its volume when hydrated, forming a low-permeability seal that prevents water seepage.

It is also known as: Pond Sealant Bentonite, Waterproofing Bentonite, Swelling Clay for Sealing Ponds.
