PP PE Breathable Proof Breathable House Wrap Waterproof Membrane For Wall

Waterproof membrane is a flexible building material product, mainly used for waterproofing and moisture-proofing of building walls, roofs, tunnels, roads and other projects, forming a waterproof barrier through the leak-free connection between the membrane and the base. Its core properties include water resistance, temperature stability, aging resistance and flexibility.

The new waterproof material has strong anti-permeability, simple construction and operation, fast speed, easy to master, etc. It is widely used in waterproofing of roofs of high-end buildings, waterproofing of underground projects, waterproofing of tunnel tops, leakage of landfills, etc., and has a wide range of uses.

Typical application scenarios

1. Roofing projects: SBS/APP modified asphalt membrane (cold/hot areas), TPO (single-layer roofing).

2. Underground projects: self-adhesive membrane (anti-deformation), PVC (corrosion-resistant).

3. Industrial scenarios: root penetration-resistant membrane (roof greening), EPDM (acid and alkali resistance in chemical plants).

Key points for purchase and construction

1. Quality identification:

· Check whether the base (polyester felt is better than composite felt) and the cross section are evenly impregnated.

· Check the test report (such as GB 18242 standard).

2. Construction adaptability:

· Select SBS type in cold areas and APP type in high temperature environments.

· Self-adhesive rolls must ensure that the base layer is flat to avoid hollowing.

3. Environmental protection and standards:

· Avoid using composite tires and recycled materials (listed as restricted products).
