When you mix bentonite pond sealant with water, it will expand and create a low permeability gel. The mixture sits over the pond soil, sealing gaps and holes. In dry ponds, you can mix it with the pond soil to create a high effective pond liner with outstanding self-repair capabilities.
Applying the pond sealant on a new or drained pond is like installing a pond liner.
The process begins with cleaning the pond surface, then you have to evenly spread the bentonite using a tractor that can lift more than 3000 LB (a super sack). Once the pond is covered, mix and compact the bentonite with the pond soil. Finally, fill it slowly to give bentonite the time to expand and create the waterproof seal.
This process is called Blanked method and will ensure that your pond will hold water for a long time.
To Apply pond sealant on a pond with water, you have to sprinkle the water surface with a layer of bentonite and let it sink.
Bentonite granules will sink and filter into the soil gaps and cracks while expanding and creating the seal.
Depending on the size of the pond, you will require a small boat to reach the center or use a pneumatic trailer to spread the sealer.
For isolated leaks, there are also several ways to apply bentonite as a pond sealer.
When the leak is easily identified and the water is flowing through it, a bentonite slurry is applied. The idea is for the slurry to flow through the leak leaving the sealant in the gap, which will swell inside said gap until a seal is created and the flow of water stops altogether.
When the leak is identified but there’s no water flow towards or through it, the sealant can be applied using pressure tools, basically “firing” the bentonite or a bentonite slurry to the affected area, getting the bentonite to sit in the required leaking area to prevent water seepage.
The critical factor when it comes to the amount of bentonite required to seal a pond or an area of the pond is the type of soil. The more porous the soil is, the more bentonite per square foot is required. If you use less than the recommended amount of bentonite, it is possible that will affect the efficiency of the seal. Usual application rates go from 2 to 5 lbs per square foot.
To the right (or below) you can find a REFERENCE TABLE, based on a maximum depth of 8 ft and a general purpose pond, indicating the amount of bentonite required per square foot.
The other factor is area of the pond. To approximate the area you can follow the formula (W + (2 x DP )) x (L + (2 x DP)) where W is width, L is Length and DP the deepest point.

Across all aspects of our products, we have formed a great relationship with Lonestar Bentonite and their dedication to our business is obvious. We appreciate their attention to detail and their creative approach to meet our niche
Fast response and great turnkey service. We needed several truckloads of bentonite for sealing at our construction site. Not only did they arrange prompt delivery, but they executed the trenching and application. Art from their team was very helpful in ensuring everything was conducted without a hitch. A+
The product appears to function as announced for my pond. The results where very very pleasing. Quick service along with great customer service and they followed through with a timely delivery.
Amazing service!! I wouldn’t go to anyone else!
Purchased 12,000 lbs of a bentonite blend for our water treatment unit. Product performed better than the other blend we were buying and saved over 25%. Will do more business with them!
Used 2 lbs per sq/fr of Lone Star’s Premium sodium bentonite on our 1/2 acre pond. They explained how to apply the product and we got great results. Our pond holds water now. Definitely recommended!
Great experience working with Arturo, Ricardo and the team at Lone Star GTC. After thoroughly researching various products and receiving bids from multiple contractors for the re-construction and improvement of two existing livestock ponds that did not hold water, we trusted Lone Star to handle the process from start to finish using their preferred team of sub-contractors. The bentonite product that Lone Star sells is very high quality. It has a fine, baby-powder like consistency. When mixed with the aggregate & clay that was already on site, the result was a water-proof barrier that will last for decades. Whether purchasing the bentonite product for a DIY project or contracting Lone Star for larger pond/lake projects, you can trust them to deliver excellent service and exceed expectations. 5 STARS for quality, service and value.
Professional advice on how to seal our pond. Product worked great. Highly recommended.
My business is simple. I design ponds. Lonestar has been my main supplier of bentonite for the past 7 years. They are honest, hard-working, and have never let me nor any of my clients down. With pleasure, I sure do recommend them!
