Pre-Laid Self-Adhesive Waterproof Membrane

Product Description

Yuhong Self-Adhesive waterproof membrane adopts high-density polyethylene (HDPE) as the main waterproof layer, which is composed of self-adhesive layer, protective layer (for environmental change), and isolated layer. The self-adhesive layer and protective layer have self-healing function. This waterproof membrane reserves a *0 mm wide self-adhesive overlap edge on the long side. After its reaction with liquid state concrete mortar, a seamless combination between the waterproof layer and concrete structure is achieved, which improves the reliability of the waterproof system. Yuhong HDPE waterproof membrane has found a wide scope of applications, and is widely applied in underground projects.

Features of HDPE Self-adhesive Waterproof Membrane:
1. New wet bonding technique: After moisture curing reaction between cement slurry and high polymer, the membrane and the structural layer are firmly bonded, improving the reliability of the waterproof layer.
2. The waterproof membrane is not bonded with the substrate, so the sedimentation and deformation of the substrate will not affect the waterproof performance.
3. Excellent shock resistance and puncture resistance: Can withstand the working load and the attack of the reinforcement cage, eliminating the need for special protections.
4. Strong self-healing function: Unique self-healing capacity for slight construction damage.
5. Outstanding chemical resistance: Good resistibility towards the alkali water from the concrete, home scrap has no effect on it.
6. Wet construction, remove the need for leveling layer, the construction is not limited by the condition of weather.
7. Minimal surface treatment: Doesn't need oil or heat to dry the wet substrate, with no volatile substance.
8. Have no need for cement mortar protective course.
9. Cold construction, need no cementing agent, safe and environment-friendly.

Application Scope:
Our self-adhesive waterproof membrane is suitable for various kinds of underground cave depots, tunnels, subways, and other municipal waterproof projects.
