Product Description

Product Description

Solutions To Water Containment Needs - Bentonite Waterstops
Bentonite waterstop is a kind of hydrophilic water sealing product coming with incomparable durability and higher water absorption no less than 300%. Unlike traditional clay based waterstops, this one utilizes rubber as base material to form a controlled, moisture active sealant - that means the bentonite waterstop will not expand to point losing much of integrity even being washed away by water during continually expansion.

The production and quality control of our waterstop strips strictly adhere to authoritative national and industry standards. They mainly comply with Polymer Waterproof Materials - Part 2: Waterstops (GB/T 18173.2-2014), meeting the requirements in product classification (including water-swelling type, rubber type, etc.), physical and mechanical properties (tensile strength ≥3.5MPa, elongation at break ≥350%, hydrostatic expansion rate ≥200% for water-swelling type, etc.), as well as weather and medium resistance. For composite waterstop strips, they also meet the stability requirements for expansion components specified in Concrete Waterproofing Admixtures (GB 8076-2008). Meanwhile, the products conform to industry-specific standards: water-swelling variants meet the expansion durability and impermeability requirements of Water-Swelling Waterstop Adhesive (JC/T 2037-2010); for water conservancy and municipal scenarios, they comply with the water pressure resistance and tear resistance requirements of Technical Specification for Waterstops in Water Conservancy and Hydropower Projects (SL 325-2022), and the compatibility requirements of Unified Standard for Construction Quality Acceptance of Municipal Engineering (GB 50334-2013). In addition, each batch of products undergoes sampling testing before leaving the factory with an attached quality inspection report; some high-end models have also obtained international certifications such as SGS and CE, and customized products meeting local standards (e.g., EU EN 13967) can be provided on demand, fully ensuring the reliability of engineering waterproofing.
