The Natural Solution for Sealing, Absorption, and Protection
What Is it?
Sodium bentonite is a naturally occurring clay formed from volcanic ash. Known for its exceptional swelling and sealing properties, it can absorb large amounts of water and expand up to 15 times its dry volume. Because of this, it’s one of the most versatile industrial and environmental materials available today.

When hydrated, sodium bentonite forms a thick, gel-like barrier that’s completely impermeable to liquids. This makes it an excellent choice for sealing ponds, landfills, foundations, and drilling sites.
Main Uses and Applications of Bentonite
1. Pond and Lagoon Sealing
One of the most popular applications of sodium bentonite is pond sealing. When applied correctly, it prevents water loss by creating a natural waterproof layer. It’s a safer and more cost-effective alternative to plastic or concrete liners, making it ideal for farmers, ranchers, and landscapers.
2. Environmental Protection
Sodium bentonite is widely used in waste containment systems, such as landfills and hazardous waste sites. It stops contaminants from leaking into groundwater, helping meet environmental regulations and ensuring long-term protection.
3. Drilling and Construction
In the oil and gas industry, sodium bentonite acts as a drilling mud additive, lubricating drill bits and stabilizing boreholes. In construction, it’s used for waterproofing foundations, tunnels, and retaining walls.
4. Cat Litter and Industrial Absorbents
Because of its natural absorbent qualities, sodium bentonite is also used in clumping cat litter and various spill-control products. It effectively traps moisture and odors, offering both practicality and sustainability.
Advantages of Using Bentonite
Natural and Eco-Friendly
Sodium bentonite is 100% natural and non-toxic. It provides an eco-friendly alternative to synthetic liners and chemical sealants.
Cost-Effective
Compared to other sealing materials, bentonite is affordable, easy to apply, and requires minimal maintenance.
Long-Lasting Performance
Once installed, a bentonite barrier remains effective for decades. Its self-healing ability—expanding to fill small cracks—ensures lasting protection and performance.
