Dry pond, Low water level

Fix it with Bentonite pond sealer

Low-level water and dried ponds are a common problem. The common solutions are expensive and complicate to apply but, Bentonite Pond Sealer is cost-efficient and easy to apply

How Bentonite Pond Sealer works?

Lonestar Bentonite Pond Sealant is a natural mineral that can fix any pond leak.

When you apply it on water deposits like ponds or lakes, it will deposit itself at the bottom, inside the soil pores and cracks, creating a very efficient, safe, and long-lasting seal.

The working principle of our Bentonite sealant is base on the natural property of Bentonite to absorb water and expand itself up to 10 times.

Lonestar Pond Sealer’s effectiveness is due to the calculation of the mix-mesh powder and the quantity of product that each type of soil requires. The Lonestar special formula has been developed over 50 years of fieldwork.

Bentonite Sealer is easy to apply in either dry or wet ponds (ponds that can’t be drain), is a 100% natural earth sealer, and is safe for fish, plants, stock, and swimming.

Peter Stavros

We hired Lonestar Bentonite to work on a stock pond We have at our property In Millet, Tx.

The price was competitive, service was great, but most important, the pond holds water now. Art and Ricardo are professional friendly folks. Highly recommended!

Inigo Arzac

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+
