Elastomer-Modified Asphalt Composite Copper-Backed Root-Resistant Waterproofing Membrane

Applicable Standards：GB/T 35468-2017；Q/YZQ-004-2026

Prouduct Introduction

　　This roll-formable sheet waterproofing membrane is manufactured using a copper-reinforced base composite of continuous-filament polyester felt as the substrate, with SBS-modified asphalt—enhanced with imported chemical root-barrier agents (from Bische-Hofmann, Austria, and Lanxess, Germany)— as the coating material, and a polyethylene film as the separating layer on the surface.

Product Features

　　1、It offers both waterproofing and root-barrier functions, and its performance surpasses that of similar products.

　　2、Made with imported chemical root barriers that do not migrate or leach out, it effectively prevents roots from penetrating the waterproofing layer over the long term without affecting plant growth.

　　3、Excellent resistance to corrosion and mold.

4、Ensuring the integrity of green roofs and landscaped parking garage roofs.
