High-Density Polyethylene Pre-Applied Membrane (HDPE)
High-Density Polyethylene Pre-Applied Membrane (HDPE - Betoflex HPS) is a fully bonded pre-applied waterproofing membrane engineered with a tough HDPE carrier sheet, pressure-sensitive adhesive layer, and weather-resistant protective coating that forms a permanent mechanical bond to poured concrete.
Product Overview
This product range offers advanced material performance and long-term durability. Formulated to meet high standards of protection and reliability under various site conditions. High-Density Polyethylene Pre-Applied Membrane (HDPE - Betoflex HPS) is a fully bonded pre-applied waterproofing membrane engineered with a tough HDPE carrier sheet, pressure-sensitive adhesive layer, and weather-resistant protective coating that forms a permanent mechanical bond to poured concrete.
Best-fit Applications
- • Pre-applied waterproofing under foundation raft slabs and thick concrete mat footings
- • Blindside waterproofing for shotcrete, diaphragm walls, and contiguous pile walls
- • Underground basement infrastructure, railway tunnels, and deep substructures
- • Protection against methane, radon, and hazardous soil gas ingress
Technical Benefits
- • Forms an active mechanical bond to wet concrete, eliminating lateral water migration
- • Unaffected by ground movement, moisture, or aggressive soil chemicals and salts
- • Provides robust methane, radon, and soil gas barrier performance
- • Can be walked on directly after placement prior to concrete pouring
