HDPE polymer self-adhesive film waterproof membrane adopts high-density polyethylene as base material, compounded with special self-adhesive layer and release film. Adopting pre-laid reverse-bonding technology, the membrane is pre-laid on bedding layer, and post-poured concrete bonds tightly with adhesive layer, eliminating water channeling between waterproof layer and structural layer. It is a dedicated waterproof material for underground projects.

1. Substrate Treatment: Make bedding surface flat, remove sharp debris and stones. No standing water is required; construction is allowed on damp base.
2. Pre-lay Membrane: Lay the membrane with sand-adhesive side towards concrete structure. Spread on bedding layer following layout lines and align membrane laps.
3. Lap Joint Treatment: Remove release film for long-side and short-side laps, bond self-adhesive layers together. Apply reinforcement layers at corners and internal/external angles.
4. Membrane Fixing: Fix and seal membrane ends and laps with pressure strips to prevent displacement.
5. Finished-product Protection: Prevent puncture by sharp objects after laying. Proceed with steel bar binding and concrete pouring timely.
6. Concrete Pouring: Pour post-poured concrete directly on membrane. Concrete will bond tightly with adhesive layer to achieve pre-laid reverse-bonding effect.
Note: For pre-laid application only. Not for exposed use. Hot-melt construction is forbidden.
