Product Description
Wet‑laid Self‑adhesive Waterproof Membrane Basement Slab Basement Side Wall Underground Garage
Product Advantages
Can be constructed on damp substrates. Installation is allowed when there is no standing water on the base, no need to wait for the substrate to be fully dry, shortening the construction cycle.
Full adhesion by cement slurry wet‑laying delivers excellent anti‑water‑channeling performance, making leak points easy to locate and repair.
Cold installation without open flame eliminates fire risks. Suitable for fire‑prohibited working areas, environmentally friendly and pollution‑free.
Good flexibility to accommodate minor cracking and deformation of the substrate. Self‑adhesive sealing at overlap edges ensures tight joints.
Resistant to acid and alkali corrosion with outstanding water penetration resistance, providing stable overall waterproofing and damp‑proofing performance.

Application Scope
Suitable for waterproofing and damp‑proofing of basement slabs, basement side walls, underground garages and civil air‑defense projects; indoor restrooms, kitchens and balconies; auxiliary waterproofing for non‑exposed roofs, pools, utility tunnels and tunnels; renovation and leak‑repair projects for old buildings. Not for exposed use. A protective layer must be applied upon completion.
Construction Method
Substrate treatment: Remove debris and dust from the base surface. Ensure the surface is flat, damp and free of standing water.
Prepare cement slurry: Mix cement with water to obtain well‑proportioned cement slurry without lumps.
Apply cement slurry: Scrape and spread cement slurry evenly over the substrate surface.
Lay the membrane: Peel off the release film, lay the membrane onto the cement slurry, roll to expel air and achieve tight bonding between membrane and slurry.
Overlap treatment: Remove release film from membrane overlap edges, press firmly for self‑adhesive overlapping. Keep overlap width compliant with specifications.
Edge sealing: Carry out proper sealing treatment for membrane terminal edges.
Curing and protective layer: Install protective layer promptly after cement slurry cures. Long‑term sun exposure of the membrane is prohibited.
