Bentonite Pond Liner is a great alternative to polymer liners. You can obtain the same benefits plus it is environmentally friendly, natural and non-toxic. Aditionally, it is puncture and tear free and suitable for cattle, livestock, irrigation and wildlife.
Well applied, bentonite pond liner can last for decades without any major maintenance.
Count on a full pond when you most need it.
Sodium bentonite is a natural clay that swells up to 12 times its size. The bentonite is applied to the bottom of the pond and swells at contact with water, therefore creating a layer of compacted clay soil that will help hold water inside the pond. Unlike rubber or plastic liners, bentonite can fill any gap, slit or crevice, sometimes around a tree root or a rock. One of its biggest advantages? No puncture risk. Sodium bentonite keeps your pond as close as possible to a natural environment. Being a 100% natural clay, you add to the ground a component that will blend perfectly into the pond’s ecology and give you an excellent result for a very low cost and a very long time.

To apply the liner only some simple construction equipment is required, the kind that can generally be found at most farms and ranches. Professional application is highly recommended, or professional guidance if you choose to DIY.
There are 2 main methods for applying bentonite clay as a pond liner. It will depend on the condition of your soil and your pond to choose the best one for your particular needs. For both methods, start by cleaning the pond site as much as possible. Remember we need to compact the bentonite layer we will apply, so remove debris or any other materials that can get in the way of the compaction process.
It tends to be the most effective bentonite application method. Start by removing about 6-8 inches of soil and depositing them by the edges of the pond or lake. Add the layer of bentonite, attempting to create a layer as smooth and even as possible. Drop back in the soil that was removed from the area, and proceed to compact the soil to become an even layer on top of the bentonite layer, “trapping” the bentonite between the soil of the pond and the soil that was removed in the first step. Slowly fill the pond or lake, in order to avoid disturbing the recently created layer of bentonite. Allow 3-5 days for the bentonite to activate and naturally create the waterproof seal.
This method doesn’t require removing soil from the bottom of the pond. Just till or disk the bottom of the pond about 8-12 inches deep. Deposit the bentonite into the tilled soil and mix it into the ground using a similar process (can be raking too) to mix the bentonite into the layer of soil that was tilled. The goal is to obtain a soil-bentonite mix that is as even as possible throughout the bottom of the pond. Compact the mixed soil-bentonite layer and slowly let the water flow into the pond, trying to disturb the recently created layer as minimum as possible. Allow 3-5 days for the bentonite to activate and naturally create the seal that will prevent water seepage.
The amount of bentonite pond sealer varies according to the type of soil of the site of the pond. For very porous soils that are made mostly of rock and gravel, it is usually recommended to use between 5 and 6 lbs per square foot of surface, while for a soil with some clay in its composition it is between 1 and 2 pounds per square foot. Keep in mind that when we refer to “surface” or “area” we mean the area of the bottom of the pond, which is a volumetric surface. Many people calculate the area as if it were a flat surface, consequently obtaining an incorrect amount of required bentonite pond liner.
The present table offers a reference, depending on the volumetric surface of the area of your pond and the type of soil at the pond’s location.
Lonestar Minerals is a bentonite wholesaler. Over time, it has developed its own “formula” for pond liner, using sodium bentonite as the only ingredient. Our Bentonite Pond Liner Mix Mesh is unique and has been developed using our 50+ years of experience in the field. We are involved in mining our bentonite to milling and delivering a selected type and quality bentonite for your industry and application.
The mix of bentonite particles and granular bentonite allows us to take advantage of the properties of both grain sizes, helping reduce the amount of bentonite required per square foot* (*compared to other sources of bentonite clay for ponds).

Is bentonite better than passive pond liners?
Every pond liner has it’s advantages and disadvantages and, of course, there are several schools out there. We believe that passive pond liners are a good option for garden ponds (maybe two or three thousand square feet), but when it comes to farm ponds, ranch ponds or artificial lakes, bentonite is less prone to puncturing or degradation. In our experience the initial investment is quite similar. Still, bentonite has the upper hand in the long term, with fewer maintenance costs and creating a natural pond ecosystem and not just a water retention tank.
Can I apply the bentonite by myself?
When purchasing the bentonite with us, we are pleased to guide you through the process of applying the bentonite yourself if you have the equipment and the willingness to do so. If it is not possible to do the application yourself for any reason, we are also able to take our team to your property to do the application process for you.
Does the pond have to be empty to be lined with bentonite?
We recommend applying the bentonite to a dry pond. It can be applied to a pond with water (wet application), but that introduces several more variables into the equation, and it may not be as effective as applying it to a dry pond.
What are the other uses of sodium bentonite clay?
Sodium bentonite is used in many different industries. Some examples are drilling mud for construction or oil industries, pond liner and pond sealer for farms, ranches, golf courses and other venues, groundwater barrier for treated water, binding agent for green sand molds in foundry, cat litter for the pets industry, among others.
