★★★★★ Great company! Professional quality work at a flat price! Highly recommend!Donnie B. ★★★★★ Very professional group to work with. Everyone communicates well with you as a client and with each other. They also took photos along with texting updates which was helpful for documentation.Would highly recommend them.Gary R. ★★★★★ 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. ★★★★★ I needed some Bentonite for a small project. I had trouble locating what I needed until I called Lonestar. They started working with me on Saturday morning and getting me all the information I needed for a load on Monday. They helped me get the amount of material I needed and made the process very easy. Super nice staff that helped me with payment and Rick got me loaded up. Great folksAll around. Highly recommend. Give them a ring and let them get you fixed up!Jason D. ★★★★★ Did a great job in applying Bentonite to our pond. From the start Rick was extremely helpful in setting up or project.

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. ★★★★★ 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.

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.
