Product Description

Non-asphalt Hdpe Self-adhesive Waterproof Membrane

Core Advantages of Sand‑surface HDPE Pre‑laid Waterproof Membrane

1. Stable and durable dual-sided structure: The backing layer improves the membrane’s tensile resistance, tear resistance and deformation resistance, reducing construction damage. The sand-surface self-adhesive layer strengthens occlusion with concrete and enhances the overall dimensional stability of the membrane.

2. Complete prevention of water channeling and leakage: Adopting pre-laid reverse bonding technology, the sand surface achieves physical occlusion and tight bonding with post-poured concrete, integrating the waterproof layer with the building structure and thoroughly solving hidden problems of interlayer water channeling and hollowing leakage.

3. Excellent damage resistance: The HDPE base material features excellent toughness, high puncture resistance, tensile and tear resistance. It can resist extrusion and puncture caused by steel bars and gravel during construction, adapting to complex underground construction environments.

4. Safe and convenient construction: Full cold construction without open flame and hot melting. It can be constructed directly on damp substrates, ensuring high construction safety for operation in confined underground spaces.

5. Corrosion resistance and long service life: Made of non-asphalt material, it resists acid, alkali, groundwater and soil corrosion without aging and material migration, maintaining stable long-term waterproof performance in underground environments.

6. Engineering cost saving: No additional cement mortar protective layer is required, which simplifies construction procedures, greatly shortens the construction period and effectively reduces the overall project cost.

Construction Process

Substrate treatment: Clean sharp stones and sundries on the base surface, keep the surface flat. Damp surface is acceptable, but standing water is forbidden.
Directional laying: Place the membrane with the backing side down against the base and the sand surface upward facing the concrete, lay flat along the elastic line and align the lap edges.
Lap sealing: Tear off the release film at the lap joints and compact the bonding edges. Apply waterproof reinforcement layers at internal and external corners and detailed nodes.
Edge fixing: Compact and seal the membrane ends and lap edges with pressure strips to prevent displacement, blistering and warping.
Finished product protection: Avoid sharp object impact and puncture. Complete steel bar binding in time to prevent long-term exposure and damage of the membrane.
Concrete pouring: Pour concrete directly on the sand surface of the membrane. The sand surface interlocks and solidifies with concrete to form an integral waterproof structure without water channeling.

Application Scope

Building underground works: basement slabs, underground garages, underground side walls.
Rail transit works: subways, tunnels and underground caverns.
Municipal underground works: utility tunnels, underground passages and structures.
Civil air defense underground projects.
