Sealing a pond with bentonite clay is the most effective way for making a pond able to retain water. You can fix the leaking pond with bentonite in many ways like the sprinkle method, blanket method and mix blanket method. The simplest of all is the sprinkle method.

You just have to sprinkle this bentonite clay in the leaking area by hand or by using broadcast spreader. For this method you have to use granular bentonite. You have to use 5 pounds of this bentonite clay for each square foot. Don’t forget to wear a face/dust mask while doing this.

Instructions

The amount of bentonite clay that is required to seal a pond depends upon the porosity of pond soil. Porosity is more when high seepage of water occurs.
Bentonite is a natural substance. It is non toxic to fish.
First remove all the debris from the pond while you add the bentonite clay in the pond. Using the blanket method:

  • Do not leave any blank space.
  • If you don’t want to disturb the bentonite layer then add the water carefully.
  • You have to maintain a good depth of soil layer.
  • Don’t perform this method if the weather is too hot.
