Product Overview
Multi-Layer Composite Waterproofing Solution
Polyethylene Polypropylene (PP/PE) composite membrane is a high-polymer waterproofing material designed for professional anti-seepage projects. Its unique multi-layer structure, featuring a dense PE core film laminated between high-strength non-woven PP fleece, provides both professional-grade watertightness and superior bonding capabilities.
Perfect for bathrooms, basements, and large scale infrastructure, this membrane is favored for its wet-base compatibility and ability to bond directly with cement-based mortars. As a specialist manufacturer, Tianyuan supports full OEM customization, providing tailored thicknesses, roll weights, and colors for global building material distributors and contractors.

Installation Guide
Base Preparation
Clean the surface. Ensure it is firm and free from dust, oil stains, and standing water.
Adhesive Mixing
Prepare the polymer cement mortar or dry powder adhesive according to project requirements.
Uniform Coating
Apply the adhesive evenly to fill small holes and rough areas on the base course.
Laying Membrane
Pre-pave the PP membrane straight and flat, ensuring no wrinkles or air pockets.
Compaction
Press the membrane firmly to achieve full bonding with the adhesive layer and substrate.
Sealing Joints
Treat overlaps carefully with specialized sealing tapes or adhesive paste to prevent leaks.
