Thermoplastic Polyolefin (TPO) Root-Resistant Waterproofing Membrane

Applicable Standards:GB/T 35468-2017、GB 27789-2011

Product Introduction

This product is a rollable sheet-type waterproofing membrane made from high-quality thermoplastic polyolefin (TPO) resin granules using advanced manufacturing processes.

Product Features

　　1、Special formulation technology; no plasticizers added; features high flexibility and does not become brittle due to plasticizer migration, ensuring longlasting waterproof performance.

　　2、Excellent flexibility at both high and low temperatures: It remains flexible at -40°C and retains high mechanical strength at higher temperatures.

　　3、Resistant to corrosion from acids, alkalis, salts, animal and vegetable oils, and lubricants; resistant to the growth of microorganisms such as algae and mold.

　　4、High resistance to heat aging and good dimensional stability.

　　5、Light colors, primarily white, with a smooth surface; they offer good energy-saving performance and are stain-resistant.

　　6、The overlaps are joined using hot-air welding, which creates a high-strength seal.

　　7、Root Puncture Resistance: Its dense molecular structure and exceptionally strong seam strength provide excellent physical resistance to root penetration.

Key Performance Indicators

Recommended Level 1 Waterproofing Design Plan

Scope of Application

　　Suitable for green roofs, underground ceiling slabs, and areas where root penetration must be prevented.

Construction Methods

　　Substrate Preparation → Installation of Standard Waterproofing Layer → Installation of RootResistant Waterproofing Layer → Hot-Air Welding of Overlaps → Treatment of Detail Junctions → Quality Inspection and Acceptance → Installation of Protective Layer / Installation of Siphon Drainage System

Storage and Transportation

　　1、Products should be stored separately by type, specification, and production date. Storage areas should be dry and well-ventilated, protected from direct sunlight and rain, and must not come into contact with chemicals that may react with them.

　　2、The shelf life is 1 year from the date of manufacture.
