★★★★★ Professional advice on how to seal our pond. Product worked great.Highly recommended.Manuel C. ★★★★★ Working with Lonestar was a pleasure from the start to the finish of the project. Ricardo (Rick) came out to walk the area and discuss the best option, and provided a detailed estimate within a couple days of initial contact. Next was meeting Joseph and his crew that did the excavation and application of the Bentonite. The process moved really quickly considering the work involved, and the entire team was extremely personable and professional. Overall I was very pleased with the entire experience and would recommend Lonestar to any potential customer without hesitation.Chris P. ★★★★★ We have being providing Lone Star GTC freight services for over a year. Diego in charge of logistics is a pleasure to deal with and payment on our services has always being on time. This review is not about their product but about their professionalism and business ethics. Good honest folks that still can do business on a handshake.Trustar L. ★★★★★ We ordered 180,000 Lbs of sodium Bentonite from Lonestar for a project at our property in Washington state.The whole team at Lonestar were professional, friendly and knowledgeable. One of the trucks was delayed yet the communication was always there. Highly recommended.Isabel M. ★★★★★ 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. ★★★★★ 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. ★★★★★ Fast response and great turnkey service. We needed several truckloads of bentonite for sealing at our construction site. Not only did they arrange prompt delivery, but they executed the trenching and application. Art from their team was very helpful in ensuring everything was conducted without a hitch. A+Inigo A. ★★★★★ 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. ★★★★★ Great company! Professional quality work at a flat price! Highly recommend!Donnie B. ★★★★★ We had a wonderful experience working with LoneStar Minerals. Footbridge Foundation is a foster-based animal rescue, and we provide cat litter to all of our foster homes as well as the cats receiving care in our clinic.We go through litter incredibly quickly, and it can be a significant expense for a smaller nonprofit.When we recently ran out, LoneStar Minerals graciously stepped in and donated an incredible 5,000 pounds of bentonite cat litter to help us continue caring for the cats in our rescue.David and Arturo were both incredibly kind, knowledgeable, and helpful throughout the process. They took the time to answer our questions and make sure we had exactly what we needed.We’re incredibly grateful for their generosity and support of our mission. If you’re looking for bentonite or other mineral products, we highly recommend LoneStar Minerals.They’re an honest, knowledgeable company and wonderful people to work with.Footbridge Foundation Animal R.

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.
