Pe Pp Moisture Proof Layer Roll On Foundation Waterproofing For Underground Garage Planting Roof

Pe Pp Moisture‑proof Layer For Underground Garage Planting Roof

Product Introduction

Aluminum-core root-resistant PE-PP composite waterproof membrane is a polymer root-resistant waterproof sheet. Modified polyethylene serves as the main waterproof layer, with embedded aluminum foil core as the key root-barrier layer. High-strength polypropylene non-woven fabric is laminated on both sides through integrated hot-press forming process. The inner aluminum foil core effectively blocks penetration from plant roots. The mesh pores of polypropylene non-woven fabric realize mechanical interlocking with cement mortar for cold wet-laid installation. Combining waterproofing, root resistance, corrosion resistance and anti-aging performance, it solves the defect of ordinary PE-PP membranes without root-resistance. It is an integrated waterproof & root-barrier material specially designed for green roofs and planted decks.

Product Features

1.Excellent root-penetration resistance: Built-in aluminum foil core effectively stops plant root piercing. Realizes integrated waterproofing and root-barrier without separate root-resistant layer.

2.Reliable wet-laid bonding, no water channeling: Double-sided polypropylene non-woven fabric interlocks integrally with cement mortar. Cold flame-free wet-laid construction is available on damp substrates, avoiding hollowing and hidden water channeling risks.

3.Superior impermeability: Composite structure of modified polyethylene and aluminum core features dense texture, high water-pressure resistance and good moisture-barrier performance.

4.Corrosion & aging resistance: Resists acid-alkali soil and groundwater erosion. With anti-aging additives, it maintains stable long-term performance under soil cover.

5.Good mechanical performance: High tensile strength and toughness, great puncture resistance. Tolerates minor base settlement and deformation without cracking.

6.Eco-friendly: Non-toxic and pollution-free, no harmful substance leaching, suitable for green projects and water tanks.

7.Easy installation compatible with conventional processes: Flexible cutting, simple lap joint and convenient detail treatment at corners and pipe roots. Same construction method as standard PE-PP membrane to lower site difficulty.

Scope of Application

1.Planted roofs, roof gardens, underground garage green decks for integrated waterproof and root-barrier purpose.

2.Municipal green decks and sponge-city projects.

3.Basement top slabs, landscape pools with anti-root requirements.

4.Civil air-defense projects and covered roof waterproofing.

5.Waterproof & root-resistant systems for landscape and residential greening projects.
