Description
A 1.5 mm nominal thermoplastic membrane reinforced with a 90 g/m² polyester reinforcing scrim, integrally bonded to an XP Technology Core. Polymer technology provides performance in a wide range of ground contaminates, including high-salinity conditions.
The barrier performance starts with a thermoplastic membrane with welded seams, providing a monolithic watertight barrier layer. The thermoplastic membrane is reinforced with a polyester reinforcing scrim and is produced with DuPont’s Elvaloy-KEE® (Keytone Ethylene Ester), a solid phase high molecular weight ethylene interpolymer.
Features and benefits:
- Does not experience phase separation and migrate out; thus the membrane properties are maintained for long term performance.
- Provides chemical resistance properties.
- The XP Technology Core layer is integrally bonded to the Elvaloy-KEE® thermoplastic membrane.
- The XP layer is designed to activate with water to swell and form a positive seal. Thereby, at any unforeseen puncture or installation defect, the XP layer reacts at the breach, self-sealing to stop the water ingress.
- Welded thermoplastic membrane composite with reactive, self-sealing XP technology feature.
- The membrane can be continued under the floor slab and up onto a horizontal deck to provide a continuous, uniform waterproofing system.
- Can be used to waterproof structures under continuous or intermittent hydrostatic pressure.
