pre-applied, fully bonded HDPE membrane consists of multi-layer composite waterproofing material for superior waterproofing performance, including a layer of high-density PE film, self-adhesive polymer layer and a unique particulate layer or anti-sticking film.
pre-applied, fully bonded HDPE membrane 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.
pre-applied, fully bonded HDPE membrane is designed so as to bond fully and permanently with poured concrete against it after placing and tying reinforcement. Zhixin pre-applied, fully bonded HDPE membrane (sand/mineral finish) is supplied in multiple width of 1m, 2m to suit various site conditions.

• Waterproofing of all below grade concrete structures
• Protection of concrete foundations in contaminated and aggressive ground conditions
• Waterproofing of cut and cover tunnels for MRT, Subway, Metro
• Prevents coal gas, marsh gas, methane leakage in underground layers

• Forms a unique integral seal to concrete poured against it. This prevents lateral water migration and waterproofing performance is unaffected by ground settlement beneath slabs.
• Fully-bonded watertight selvedge laps and detailing.
• Provides complete barrier to water, moisture and gas.
• physically isolates the structure from the surrounding ground.
• Zero permeance to moisture.
• Solar reflective, being white in colour thereby reduce temperature gain.
• Very easy and efficient to install, does not require primer or fillet.
• Easy to install on permanent formwork – allowing efficient use of confined sites.
• Self protecting – reinforcement can start immediately after installation.
• Unaffected by wet conditions – cannot activate prematurely.
• Being HDPE, highly chemically resistant, effective in all types of soils and waters – protects structure from chlorides, sulphates and aggressive ground conditions.
