Sodium Bentonite
Sodium bentonite is a natural sealant and is used for sealing stock and recreational ponds, dairy and sewage lagoons, and city landfills. It is also effective as a hole plug as well as for controlling dust on highways. Sodium bentonite is one of the “most effective low cost methods” of treating porous soils. It is so effective, that the Federal Government and most states require a liner of sodium bentonite or material comparable, to be used to seal toxic waste lagoons and abandoned water and oil wells. It is environmentally safe, because it contains no chemicals, no additives, nothing toxic.
How Does Sodium Bentonite Work?
Sodium bentonite swells 15-18 times its dry size when wetted by water.
Over several years of testing, Sodium bentonite has proven to be one of the most effective sealants on the market. The United States E.P.A. has ruled that all landfills and waste disposal sites must be lined to prevent the leaching of hazardous chemicals into the existing ground water to protect the environment. The fact that sodium bentonite swells many times its mass, then forms a strong water and chemical proof seal makes it an ideal, inexpensive, permanent, and easy to install liner. Sodium bentonite is environmentally friendly and safe to use.
