HDPE-TBP Pre-laid Waterproof Membrane

Tired of waterproof liner peeling, bubbling or leaking after concrete pouring in subway and tunnel projects? Our HDPE-TBP Pre-laid Waterproof Membrane is a high-performance type of durable membranes, integrated with HDPE substrate, self-adhesive layer and anti-stick sand coating. It forms permanent bonded integration with cast-in-place concrete, and can cooperate with different geomembrane to build multi-layer anti-seepage systems as a stable waterproof membrane for underground infrastructure.   We supply customizable rolls with 1.2/1.5/1.7mm thickness, 1–2m width and minimum 20m length, fully complying with international pre-laid waterproof standards. This waterproof membrane reaches 16MPa tensile strength, 400% break elongation, over 400N nail tear strength and 350N puncture resistance. It stays crack-free at -35℃ and maintains zero seepage under 0.3MPa water pressure for 2 hours. Its bonding force between HDPE sheet and adhesive is 3 times stronger than ordinary geomembrane, with ex…
