★★★★★ 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. ★★★★★ 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. ★★★★★ Very nice people to do business with. They showed when we made an appointment and have exactly what we need and provided help and advice for us. We will be back for sure!Tyler S. ★★★★★ 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. ★★★★★ Lonestar did a FANTASTIC job on my pond sealing. The application of material was very deliberate and reshaping of the pond will add a lot of surface area. Would highly recommend them and will be using them on my next pond!!!Hat 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. ★★★★★ 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. ★★★★★ 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. ★★★★★ We purchased 3 truckloads of sodium bentonite from Lonestar, service was superb, price competitive, and most important the material quality was great! Our pond is holding water the way it is supposed to! I highly recommend Lonestar as your go to supplier!!Karla T. ★★★★★ 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.

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.
