Pre-Applied HDPE Waterproofing Membrane
Model SP-BH-005 · our reference
Pre-applied HDPE membrane: 28 MPa tensile, 71 m hydrostatic head
Overview
SP-BH-005 is a pre-applied high-density polyethylene (HDPE) waterproofing membrane built as a composite of thick HDPE film, pressure-sensitive adhesive and a weather-resistant protective coating. It uses 80 mm dual adhesive seams and is release-liner free, forming an integral bond that blocks water, moisture and gas and prevents lateral water migration beneath the slab. Published typical properties include 28 MPa tensile strength, 500% elongation, 1,000 N puncture resistance, 71 m hydrostatic-head resistance and low-temperature flexibility to –29 °C, tested to ASTM methods.
