Bitumen Self Adhesive Waterproofing Membrane Installable On Damp Substrate FOR Side Wall Roof Slab

Self-adhesive Bitumen Waterproof Membrane Installable On Damp Substrate

Product Introduction

2.0 mm Polymer‑core Double‑sided Self‑adhesive Waterproof Membrane adopts polymer sheet as intermediate core layer, covered with self‑adhesive polymer glue on both sides and protected by release film. It is a cold‑applied self‑adhesive waterproof material. Both sides feature self‑adhesive performance. One side bonds firmly to concrete base, while the other side reacts and bonds with post‑cast concrete, forming tight integration between waterproof layer and structural concrete to prevent water channeling. No hot‑melt torch is required during construction. It is widely used for basement slab, side wall and roof slab. 2.0 mm grade is mainly for pre‑applied and wet‑laid installation. It can be used alone or combined with non‑curing rubber‑bitumen coating for composite waterproof system.

Technical Indexes

Product Features

1. Double‑sided self‑adhesive for pre‑applied anti‑adhesion construction Dual‑side adhesive coating. When pre‑laid on cushion layer, it bonds mechanically with post‑cast concrete and avoids water channeling under waterproof layer.
2. Cold‑applied construction without open‑fire operation Torch‑free installation eliminates fire risk on site, safer for confined underground spaces.
3. High‑strength polymer core with good puncture resistance Robust polymer core delivers excellent tear‑resistance and puncture‑resistance against damage from steel bars and gravel during construction.
4. High tolerance for damp substrate Construction allowed on damp base surface with no standing water. Complete drying of substrate is not required, well‑adapted to underground site conditions.
5. Reliable lap bonding with high peel resistance Laps are joined by self‑adhesive glue for tight sealing and high peel strength, reducing joint‑leakage risks.
6. Good resistance to water and underground medium corrosion Polymer core resists long‑term water immersion and corrosion from soil and underground salt water, maintaining stable performance under buried condition.
7. Simple installation for shorter construction period Hot‑melt procedure is eliminated. Easy operation lowers technical requirement for workers and speeds‑up project progress.

Note: This membrane is not suitable for direct‑exposed application. Protective layer is mandatory for exposed positions.

Application Scope

1. Basement slabs, raft foundations and bearing platforms for pre‑applied waterproofing on cushion layer.
2. Underground garage roof slabs and basement exterior walls.
3. Subways, utility tunnels, civil‑defense projects and other underground structures.
4. Non‑exposed roofs, terraces and water tanks.
5. Renovation projects and confined‑space waterproofing where open‑fire work is forbidden.
