Planting Roof Pe Pp Composite Polyethylene Waterproofing Membrane Roll 50 M / 100 M
Planting Roof Pe Pp Composite Waterproof Membrane
Product Description
Copper-core root-resistant PE-PP composite waterproof membrane is an integrated hot-pressed polymer sheet. Modified polyethylene acts as the main waterproof layer, with embedded copper foil core as physical root-barrier layer. High-strength polypropylene non-woven fabric is laminated on both sides. The copper foil core provides physical barrier against plant root piercing. The mesh-structured PP non-woven fabric achieves mechanical interlocking with cement mortar for cold wet-laid construction. It integrates waterproofing and root-resistance. Compared with aluminum-core version, copper foil features better anti-corrosion performance and longer service life. It serves as all-in-one waterproof & root-barrier material for high-grade green roof projects without extra root barrier layer.

Product Advantages
1. Superior physical root-penetration resistance: Built-in copper foil core blocks plant roots physically. It outperforms aluminum-core material, suitable for planting deep-root vegetation.
2. Excellent corrosion resistance: Copper foil resists soil acid-alkali and underground microbial corrosion, avoiding rust damage during long-term buried service.
3. Cold wet-laid installation, no water channeling: Double-sided PP non-woven fabric bonds integrally with cement mortar. Flame-free construction is available on damp substrates to prevent delamination, water channeling and hollowing.
4. High impermeability & vapor resistance: Dense composite structure of PE and copper foil withstands high water pressure with reliable waterproof and moisture-barrier performance.
5. Good mechanical property: High tensile strength, tear resistance and puncture resistance. Tolerates minor foundation settlement and avoids cracking under backfill.
6. Long-term anti-aging performance: Formulated with anti-aging additives. Low performance degradation under soil cover to meet long-life waterproof requirements.
7. Eco-friendly: Non-toxic and pollution-free, no harmful substance leaching for landscape pools and green decks.
8. Convenient construction: Same working procedure as standard PE-PP membrane. Easy cutting and flexible detail handling for corners, pipe roots and deformation joints.
Scope of Application
1. High-grade planted roofs and roof gardens with deep-root plants.
2. Green decks of underground garage and planting platforms requiring durable root-barrier waterproofing.
3. Sponge-city projects, municipal green decks and landscape soil-covered waterproof-root-barrier systems.
4. Planted roofs in areas with corrosive soil conditions.
5. Anti-seepage and root-resistance for landscape pools and artificial lakes.
6. Soil-covered non-exposed waterproofing for civil air-defense slabs and building roofs.
