Polyethylene Propylene (PP/PE) Composite Membrane

Product Overview

A multi-layer high-polymer composite waterproofing membrane. It is manufactured by laminating a core film of dense polyethylene (PE) between two layers of high-strength polypropylene (PP) non-woven fleece. Produced on a fully automated continuous extrusion laminating line, it forms a composite rolling material with excellent waterproofing and breathability.

Key Benefits

• Mechanical Reinforcement: High tensile strength and mechanical resistance due to multi-layer reinforcement.
• Breathable Protection: Excellent waterproofing combined with good vapor permeability (breathable membrane).
• Wet Application: Can be applied directly on damp or wet substrates using cement-based adhesive, reducing the construction period.
• Potable Water Safe: Non-toxic, odorless, and perfectly safe for potable water reservoirs.
• Durability: Good low-temperature flexibility and long service life with thermal aging stability.

Installation Method

Bonded to the substrate using a polymer cement mortar (prepared with cement, water, and specialized polymer dry powder adhesive). Clean the substrate, apply the prepared mortar evenly, roll out the membrane, and press firmly using a steel trowel or scraper to squeeze out air bubbles. Overlaps are sealed with specialized sealing tapes.
