Turn around time, price, and communication is umnmatched. We will absolutely be using Lonestar again.Thank you LonestarJohn S. ★★★★★ Ricardo and the entire gang are top shelf! They definitely know their stuff and their customer service is second to none. I highly recommend them!!Scott W. ★★★★★ 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.

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.
