New 2021 Bentonite Calculator

Online Bentonite Calculator

To seal a pond with bentonite you need to know your pond width and length, deepest point, and the type of soil. With that information, our new online bentonite calculator will tell you how much bentonite do you need.

However, if your pond has a single leaking point and is very clear where is it, you will not need to seal the whole pond, it is recommended but not if the leak is not too big.

Contact our experts if you have any concerns, they can help you figure out the amount of bentonite that your pond would require.
