★★★★★ Great place. Art was wonderful. The storm blue a branch into pond liner. I got sodium bentonite from Lonestar GLC minerals. Two days out, pond stopped leaking! Thank you, Lonestar!!Sandy C. ★★★★★ Purchased 90k pounds ( Two truckloads) of Bentonite from Lonestar. The sales team and logistics folks were friendly, knowledgeable and professional. Highly recommended. Carla was great help.Elizabeth C. ★★★★★ 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. ★★★★★ The staff here are knowledgeable and responsive.

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.
