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.
