Tengpeng Waterstop Co., Ltd’s bentonite waterstop combines sodium bentonite clay with a butyl rubber or EPDM carrier, creating a hydrophilic sealing strip for construction joints. The product achieves water absorption of 300 percent or more by weight, swelling to form a durable, watertight seal in tunnels, basements, and reservoirs. Its design ensures controlled expansion, preserving structural integrity even under continuous water exposure.
The use of butyl rubber as a carrier distinguishes this waterstop from traditional clay-based options, providing enhanced durability and resistance to washout during expansion. Sodium bentonite is the standard material for such applications, with typical industry specifications requiring a minimum water absorption of 200 percent. The addition of rubber improves compression sealing and self-healing capabilities, critical for joints with limited movement.
This waterstop is widely used in infrastructure projects such as dams, water tanks, and sewage treatment plants, where reliable waterproofing is essential. The supplier highlights its cost-effectiveness and ease of installation, with rolls designed for quick deployment in construction and expansion joints. Buyers should confirm compatibility with their concrete structures and project requirements.
