CUSTOMER EXPERIENCE

Trusted by Customers Across the U.S.

★★★★★ Product, service and pricing were excellent! I bought a pallet of Bentonite from Diego at Lonestar GTC Minerals and highly recommend checking with them for prices and product when planning out a job. Thanks Diego!Thomas F.Thomas F. ★★★★★ I have had 4 other pond builders out to a location in the hill country of desired 1ac pond. All 4 were ready to start escavation without researching soil content, collection potential, or if a well would be needed to supplement water supply. Rick came out several times and brought with him an experienced excavation operator. He took soil samples which he tested, and lasered elevations. His bid was reasonable and in line with others. But after his research we decided that this project was not a good idea. He saved me from a bad experience. But if I was going to proceed he would have been my only choice to proceed with out of the 5 pond contractors that were interviewed.jerry H.jerry H. ★★★★★ 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. Art and Ricardo are profesional friendly folks. Highly recommended!peter S.peter S. ★★★★★ Extremely professional and very easy to work with.

Our pond is holding water the way it is supposed to! I highly recommend Lonestar as your go to supplier!!Karla T.Karla T. ★★★★★ Arthur Mendez and Ricardo Arzac are super individuals. They are so easy to talk to and are willing to take the time to listen to your problems. Both are extremely knowledgeable. I met Ricardo when I picked up a load of bentonite in Bulverde. I know he was busy, but he took the time to study some pictures I had and offer several possibilities to approach my issue. Talk to them once and you will be amazed. You can't go wrong!!Richmond E.Richmond E.js_loader

MATERIAL OVERVIEW

What is Sodium Bentonite?

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.
