★★★★★ We had a great experience with Lone Star. From the first to the last, they were extremely professional. Ricardo patiently walked us through every step of the process and answered all of our questions thoroughly. Alex was very communicative and managed his crew very well.The crew were efficient and considerate of our property. The skill level of the tractor work was beyond compare with anything we have experienced previously. Adan is an absolute master Tractor operator! This is the third time we have had our pond worked on by different companies, and this was far and away the best experience. No comparison really between the other two companies and Lone Star. I cannot recommend them enough! This is our first (And last!) Time to use the sodium bentonite, and we are expecting excellent results. The pond is beautiful and perfectly shaped. Now we just need rain!Catherine R. ★★★★★ Lonestar did an outstanding job on our 45,000 pounds of Bentonite. Turn around time, price, and communication is umnmatched. We will absolutely be using Lonestar again.Thank you LonestarJohn S. ★★★★★ 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. ★★★★★ They were extremely helpful with my leaking pond issues and went the extra mile to get me what I needed. Pond is looking greatForrest W. ★★★★★ My experience with Lone Star GTC Minerals was outstanding. Rick offered top-notch customer service, explaining all the pond details I never knew. Plus, their pricing is extremely competitive. I highly recommend them!SemperApeStrong ★★★★★ Lonestar GTC materials was great to work with. I had bentonite delivered for my pond. They communicated every step, very good pricing and friendly. I highly recommend them. Even a few week after they delivered they helped me out when they didn’t have to. If you need bentonite these are the right people.Byron S. ★★★★★ Purchased 90,000 pounds of pond sealant bentonite. We applied to our pond as directed and achieved great results! Good service, friendly staff and highly recommended to everyone.Joaquin L. ★★★★★ I called in with a question and was fortunate to speak with a gentleman named Rick. He was very helpful and it was evident that he has the experience to answer any question asked with respect to their products. He went above and beyond in helping me and had a tremendous amount of patience. If you're sealing a pond and need sodium bentonite... I suggest you call Rick.jake S. ★★★★★ We had a wonderful experience working with LoneStar Minerals. Footbridge Foundation is a foster-based animal rescue, and we provide cat litter to all of our foster homes as well as the cats receiving care in our clinic.We go through litter incredibly quickly, and it can be a significant expense for a smaller nonprofit.When we recently ran out, LoneStar Minerals graciously stepped in and donated an incredible 5,000 pounds of bentonite cat litter to help us continue caring for the cats in our rescue.David and Arturo were both incredibly kind, knowledgeable, and helpful throughout the process. They took the time to answer our questions and make sure we had exactly what we needed.We’re incredibly grateful for their generosity and support of our mission. If you’re looking for bentonite or other mineral products, we highly recommend LoneStar Minerals.They’re an honest, knowledgeable company and wonderful people to work with.Footbridge Foundation Animal R. ★★★★★ Exceeded expectations.

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.
