★★★★★ 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. ★★★★★ 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. ★★★★★ Ricardo and the entire gang are top shelf! They definitely know their stuff and their customer service is second to none. I highly recommend them!!Scott 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. ★★★★★ With great hope that sodium bentonite will repair my leaky earthen dam, I reached out to Lonestar GTC Minerals. Their Customer Service, primarily Diego M., was extraordinary! He efficiently and professionally walked me through what I should/should not expect, purchasing options, material pricing and freight. He even PROACTIVELY checked the shipping status and reached out to me when he saw an erroneous entry in the freight tracking....said he would handle any problems if needed....who does that these days? Wonderful! If you are looking for SB, Lonestar GTC Materials is the place to buy.Danielle B. ★★★★★ Lonestar Minerals provide excellent service and results for us. They sealed a leaking seasonal pond that now holds and is beautiful increasing the value of our property dramatically. Ric was great to work with, very responsive, and went out of his way to help us.Stephen J. ★★★★★ 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. ★★★★★ Lonestar Minerals really has some high quality bentonite product! Really glad I went with them, their product solved my pond leak!Jose C. ★★★★★ We got our pond sealed by Lonestar Minerals. The price was competitive, the team professional and the work swift. Our pond is holding water the way is supposed to. Thanks Team Lonestar.Fernando T. ★★★★★ Ric and Alex did a great job applying bentonite to our pond. Their pricing was favorable, communication excellent and performance thorough, timely and punctual. They were transparent in their bidding and possible add-ons if hammering was required. It was and their surcharge was very reasonable. Their operator was very professional and an expert on the machinery. Highly recommend them for any pond improvements anyone may require.George 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.
