★★★★★ Ricardo was great! From the time I started talking with him until the time that they were completed with the project was around a few weeks. Our pond was only about a quarter acre, but meeting timeliness and responsiveness in this day and age is hard to find and brings a lot of value to the customer. They did a great job getting everything cleaned up after they were completed with the project. Now we are just waiting for some rain so we can get our pond filled. If I ever need another pond to be sealed, or if I decide to increase the size of this pond, I will be calling these guys again. I would recommend them to anyone who need a pond sealed. Thanks, Ricardo, and thanks to your team!Chad R. ★★★★★ Did a great job in applying Bentonite to our pond. From the start Rick was extremely helpful in setting up or project. Everything went exactly to plan and we are very happy with the result!Steven P. ★★★★★ Rick over at Lonestar Minerals provided us with 2500 lbs of bentonite clay to seal a concrete dam that was leaking. We mixed a combination of Damit pond sealer/bentonite and has slowed the leak to merely a seep.Stan L. ★★★★★ Had a great friendly experience with Ricardo while sharing my situation with him he as well shared, his professionalism expertise on the matter regarding my septic tank.Henry B. ★★★★★ 30 Super Sacks! Great product. Great service. Great delivery.Patrick W. ★★★★★ Amazing service!! I wouldn’t go to anyone else!Maria M. ★★★★★ Extremely professional and very easy to work with. They provided us with a great product in a very timely manner. I highly recommend working with lone star materials!amy S. ★★★★★ 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. ★★★★★ 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. ★★★★★ Great company! Professional quality work at a flat price! Highly recommend!Donnie B.

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.
