Pond Seal

This revolutionary method is a new way to stop ponds, spillways, dikes, dams, and other leakages. A small, rock-like “nugget” made from sodium bentonite clay and aggregate limestone sinks to the bottom of the pond.

• Seal the leaks without draining your pond
• Clay particles expand when wet and create a solid layer for leak protection.
• It is ideal for sealing around intake pipes, muskrat holes, and cuts.
• All earthen ingredients are eco-friendly and will not alter water chemistry.
• For a 3/4″ thick coverage, apply five to 10 pounds per square foot.
