SJ2-300 pre-applied membrane
SJ2-300 pre-applied, fully bonded HDPE membrane (Plain Finished) is composed of one thick HDPE backing layer, self-adhesive polymer layer, trafficable protective coating layer and the release liner. The unique membranes realize firm bonding to poured concrete so that prevents water ingress or migration.
PRODUCT FEATURES
• 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 HOPE, highly chemically resistant, effective in all types of soils and waters - protects structure from chlorides, sulphates and aggressive ground conditions.
