★★★★★ 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. ★★★★★ I am a resident of Illinois and I contacted this company and they gave me excellent advice on how to appropriately apply bentonite to my existing pond that is leaking. It was all without purchasing anything from them. Above and beyond for customer service!Dan H. ★★★★★ Simply put, a class act !! Rick took the time to educate me without it being all about the sale. Breath of fresh air when someone in this day and age says "I will call you right back" and actually does. Will recommend this outfit without hesitation .Haywire RanchAdam B. ★★★★★ Arturo and Ricardo are exceptional people that provide a great service. They were thorough and explaining how to apply it looking forward to doing further business.Noon B. ★★★★★ 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. ★★★★★ 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 90k pounds ( Two truckloads) of Bentonite from Lonestar. The sales team and logistics folks were friendly, knowledgeable and professional. Highly recommended. Carla was great help.Elizabeth C. ★★★★★ 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. ★★★★★ What a pleasure to meet Rick, thanks so much for the helpSteven W. ★★★★★ 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.

Need Help With a Leaking Pond?
If you are not sure whether bentonite, another treatment method, or a full repair service is the right next step, our team can review the project and recommend a practical path forward.
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.
