When using bentonite as a pond liner, there are 2 factors that are key to achieving the desired sealing effect. The first is the amount of bentonite to be used per square foot. A common mistake is to use too little bentonite, therefore not achieving the desired waterproof effect. The rates usually vary between 2 and 6 pounds per square foot, depending on the type of soil of the area where the pond is located. You can get a better idea of the amount of bentonite required to line your pond using our online bentonite calculator.
The second factor is the process or method used for applying bentonite to the pond area. While it isn’t a complicated process, the steps must be done correctly in order to ensure the bentonite creates a watertight seal throughout the whole area of the pond.

There are several good reasons for using bentonite to line a pond instead of the traditional EPDM or HDPE liners. Due to the nature of the bentonite, you can rest assured it will not add chemicals to your land, therefore not affecting the ph of the water or the soil. It is ideal and safe for ponds that will contain fish and plants or that going to be used for swimming.
Resistance is another good reason. Bentonite, in it’s powdered form, it is not susceptible to tears or punctures, and it will tend to seal again small holes that may be created in the bottom of the pond or lake., Does it have a downside? Yes, it does. Bentonite swells at contact with water. When bentonite loses humidity, it reduces its size and becomes vulnerable to erosion. Therefore it is not recommended for seasonal ponds, ponds that aren’t full all year round.
Now let’s talk about the cost of lining a pond with bentonite. Bentonite itself is an inexpensive material that costs only a few cents per pound. As mentioned before, the application rate is usually between 2 and 6 lbs per square foot, so, depending on the size of your pond and the type of soil it has, your investment can go from a few dollars to several thousand. However, the investment is usually comparable, if not lower, than a traditional rubber liner, especially when we start talking about ponds that are 1/2 acre and larger.
