Quadproof Ultra Membrane – Pre-Applied Fully Bonded Waterproofing & Gas Barrier
Quadproof Ultra Membrane is a high-performance, pre-applied waterproofing and gas barrier membrane, designed for basement and below-ground structures. Engineered with a heavy-duty virgin polypropylene geotextile, this fully bonded system integrates with fresh concrete to create a strong mechanical bond—without the need for adhesives, primers, heat, or open flames.
Key Benefits:
✔ Fully Bonded System: Ensures a continuous waterproofing and gas barrier with fresh concrete.
✔ No Adhesives or Open Flames Required: Safe, efficient installation.
✔ Multi-Layer Protection: 14-layer membrane featuring two Ethylene Vinyl Alcohol Co-Polymer (EVOH) layers for superior gas resistance.
✔ Exceptional Gas & VOC Protection: Effectively blocks Methane, Radon, CO₂, Volatile Organic Compounds (VOCs), and Hydrocarbons.
✔ Pre-Applied Installation: Applied before steel reinforcement, either vertically or horizontally, for blindside or under-slab applications.
✔ Prevents Lateral Water Migration: Maintains integral waterproofing and gas control.
✔ Flexible & Easy to Install: Easily folded on-site, supplied single-wound for a lay-flat surface, and includes a taped system for cold-applied installation.
