Brief Introduction:

Dongsheng LDPE Waterproofing Membrane adopts Low-density polyethylene (LDPE) 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 70 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. Dongsheng LDPE waterproof membrane has found a wide scope of applications, and is widely applied in underground projects.



Where to use


Basement

Subway

Tunnel

Cave

Other underground public constructions.


 Features of HDPE Waterproofing 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.

10.Non-odor,pollution-free and eco-friendly materials


Application Scope:


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


Transportation and storage

1.Membrane shall be stored in  rolls with paper core inside,placing flatwise and stack  maximum for 5 layers

2.During storage and transporation,membrane shall be placed in dry and well-ventilated places with ambient temperature less than 35℃, prohibit contacting with acid ,alkali, oil,and organic solvent.

3.Shelf life of 1 year under normal transportation and storage condition.



Application:


Surface preparation→ geo textile application→ position setting→ membrane installation → wide edge overlapping → long edge overlapping → inspection & approval→ remove release film → install steel bar → concrete work.
