The DYWI® Seal waterproofing system is a needle-punched non-woven impregnated membrane. The membrane structure comprises water absorbing and water swelling polymers. An optional one-side polyethylene film on top of the needle-punched non-woven membrane and the self-healing properties of the DYWI® Seal waterproofing system ensure optimum performance for various water sealing applications.
Bentonite mats, also referred to as geosynthetic clay liners (GCL’s), are barriers used for various sealing and waterproofing applications. DYWI® Seal bentonite mats are a composite consisting of two layers of geotextiles filled with sodium bentonite.
The application range of DYWI® Seal bentonite mats comprises waterproofing, gas sealing, and usage as a vapor barrier.
