★★★★★ Fast, friendly service. 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. ★★★★★ 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.

Professional service with great communicationmike E. ★★★★★ Very professional group to work with. Everyone communicates well with you as a client and with each other. They also took photos along with texting updates which was helpful for documentation.Would highly recommend them.Gary R. ★★★★★ 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.Casey M. ★★★★★ Great company!

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.
