Natural way to seal leaking ponds, dikes, dams, spillways, etc. Sodium bentonite.

  • Seals leaks without draining the pond
  • Clay particles swell when wet, creating a solid layer of leak protection
  • Great for sealing around intake pipes, muskrat holes, cuts and tears in liners
  • Eco-friendly - all earthen ingredients, will not alter water chemistry
  • Apply at two to five pounds per square foot for a 3/4" thick coverage or ten pounds per square foot for 11/2" thick coverage
