Self-adhesive Polymer-Modified Bitumen Root-Resistant Waterproofing Membrane

Applicable Standards：GB/T 35468-2017、GB 23441-2009

Product Introduction

Self-adhesive polymer-modified bitumen rootresistant waterproofing membranes are reinforced self-adhesive membranes manufactured using a selfadhesive polymer-modified bitumen base composed of high-quality modified bitumen, rubber modifiers, special tackifiers, and root-resistant additives.

Self-adhesive waterproofing membranes (PY type) are rollable sheet waterproofing membranes manufactured using filament polyester felt as the base material, with a polyethylene film or release film as the top surface coating and a silicone release film as the bottom surface coating.

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、Guarantees for green roofs and landscaped parking garage roofs.

5、It has excellent elongation and is highly adaptable to expansion or cracking in the substrate.
