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. ★★★★★ Lonestar and Rick, Alex and Adan did an excellent job on my pond. They are the experts in pond construction, bentonite application and re-working older ponds. Adan did a great job surveying my pond and making sure everything met my expectations—he is very talented and a very hard worker. They have an extensive list of references and photos from their past projects. They were very helpful every step of the way with explanations and photos of what they were doing on my project. I highly recommend Lonestar. Thank you.Bernard J. ★★★★★ So I got screwed over by my 1st “pond expert”- terrible, can give name/info if needed . After great expense I finally did my research and consulted with several pond engineers and reputable businesses. I was advised My rocky landscape and poor soil would only hold water with an amazing bentonite seal or a thick liner with added protection. I consulted with all companies and received bids/estimates. I’m sure both would have worked but ultimately I did not want a rubber liner and all of the issues that go with it. Rick and his crew did the job “sculpting” my 1.5 acre lake as needed. They laid bentonite in blanket form, I ordered more than they recommended. They covered with 12 inches of soil, corrected the slopes etc. my pond is holding perfect, looks amazing. I am 100% satisfied with the service they have provided. Rick has become a friend and follows up frequently. Do yourself a favor and don’t go with anyone less. Im happy to discuss personally if u desire. This has worked for me.James W. ★★★★★ Ric was extremely helpful and arranged 90,000 lbs of product transported by polite and on time trucking. We undoubtedly would recommend Ric and his team for your project!Debra C. ★★★★★ Very very knowledgeable and thankful for all the help on our tank in marble fallsRyan D. ★★★★★ Lonestar GTC materials was great to work with.

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.
