Sodium bentonite is a natural sealant used for sealing stock and recreational ponds, dairy and sewage lagoons, and city landfills. It is also effective as a hole plug and for controlling dust on highways.
In Actual Field Tests water seepage has been reduced by 94%.
Sodium bentonite is one of the “most effective low-cost methods” of treating porous soils. Sodium bentonite swells 15-18 times its mass when wetted, then forms a strong water and chemical-proof seal. This makes it an ideal, inexpensive, permanent, and easy-to-install liner. Sodium bentonite is environmentally safe because it contains no chemicals, additives, or toxins.
The United States EPA has ruled that all landfills and waste disposal sites must be lined to prevent the leaching of hazardous chemicals into the existing groundwater to protect the environment. Also, liners are required as a seal for toxic waste lagoons and abandoned water and oil wells.
Our product is listed on the Texas Register under “Natural Resources.” and is approved by the Railroad Commission of Texas, Oil and Gas Division as a plugging material in seismic and cathodic protection core holes as specified in Statewide rules #99 and #100. Sodium bentonite is approved by county extension and soil conservation services.
Bentonite minerals
All bentonites will contain other minerals: Aluminum Oxide, Potassium Oxide, and Magnesium Oxide, and a percentage of sand and silt. It is the process of removing the sand and silt from the bentonite that will produce a higher-quality product.
Key to Using Bentonite to Seal a Pond
Use a high-quality sodium bentonite
Apply the product properly
Use the recommended amount based on your soil type and square footage of area being treated.
