Pre applied HDPE fully bonded waterproof membrane(sand finish)
Description
Membrane consists of multi-layer composite waterproofing material for superior waterproofing performance, including a layer of thick HDPE film, self-adhesive polymer layer and a unique particulate layer.
It can be installed on uniform and regular concrete blinding, compacted sand-stone cushion for waterproofing of below ground surfaces and is also used for waterproofing of confined surfaces or blind side waterproofing. Product is designed to bond fully and permanently with poured concrete against it after placing and lying reinforcement.
Features
1. Forms permanent bond to concrete poured against it, preventing water from seeping into the gap between waterproofing membrane and the structure
2. Not affected by the displacement of the basal layer/ ground settlement beneath slabs
3. Membrane is self-protecting. It can be trafficked immediately after application and does not require the use of protective layer
4. Simple and quick to install, requiring no priming or fillets
5. Unaffected by wet conditions
6. Fully-adhered watertight laps and detailing
7. Excellent bonding even under long-term water immersion
8.Membrane can be applied at -4ºC and above
Sand layer makes it possible to construct and work on membrane after applied without protective layer
Application
1. Waterproofing below ground concrete structures
2. Protection of concrete foundations against aggressive ground contaminants
3.Prevents methane leakage in underground layers
4. Post-applied(without sand) waterproofing system for walls and tunnels projects.
