Substrate Preparation
Ensure the surface is firm and clean. Minor surface irregularities are acceptable as the cement adhesive will fill them.

Product Overview
Cement-Bonded Composite Waterproofing for Every Surface
PP/PE (Polyethylene Polypropylene) composite waterproof membrane is a multi-layer high-polymer system that bonds directly to substrates using cement-based adhesive.
Five Engineering Advantages of PP/PE Composite
- Polymer Fiber-Reinforced Adhesion — The non-woven surface forms a full mechanical bond with polymer cement, creating a monolithic system.
- Cavity-Filling & Channel-Sealing — The adhesive fills substrate irregularities, preventing water from channeling beneath the membrane.
- Full Adhesion on Damp Substrates — The cement hydration process allows bonding even on damp concrete, accelerating construction.
- Direct Finish Compatibility — The fiber surface accepts tiles directly, eliminating the need for bonding primers.
- Root Penetration Resistance — High puncture resistance provides an effective barrier against plant roots for green roofs.

Installation Guide
Adhesive Mixing
Prepare polymer cement waterproof adhesive. Mix thoroughly to a uniform consistency suitable for trowel application.
Membrane Laying
Lay the PP/PE membrane smoothly onto the wet adhesive. Maintain a minimum 100mm side overlap.
Compaction & Air Removal
Press the membrane firmly using a rubber roller, working from the center outward to expel trapped air.
