I suggest you call Rick.jake S. ★★★★★ We hired Lone Star 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.

Having rented a trailer to haul the pallet of calcium bentonite, quick turn around was important to me to avoid additional rental charges for the trailer. I had a special request to put a portion of the load in my SUV, which they did without delay or incident. The sales transactions prior to pickup were also completed smoothly and coordination was superb. The entire experience exceeded my expectations.MG L. ★★★★★ Lonestar did an outstanding job on our 45,000 pounds of Bentonite. Turn around time, price, and communication is umnmatched.

Pond leak reviewRepair guidanceMaterial + service supportLarge-project experience
Sodium bentonite is a naturally occurring swelling clay rich in montmorillonite. When hydrated and properly confined, it expands into pores and small pathways, helping create a low-permeability barrier.
That behavior makes bentonite useful far beyond pond sealing. Lonestar supplies mineral products for water containment, drilling, treatment and industrial applications.
Pond SealingLow-permeability liners for ponds, reservoirs and lagoons.
DrillingMineral products for drilling-fluid applications.
Water TreatmentClay blends for treatment and filtration processes.
Industrial UsesFoundry, construction and other mineral applications.
