Product Description
Self adhesive HDPE Membrane
Self adhesive HDPE Membrane 302 (SDHM302)are unique composite sheets comprised of a thick HDPE film, pressure sensitive adhesive strip and weather resistant protective quartz sands. is specially designed for underground engineering construction, it can bind the later cast concrete form a firm structure. It takes the specially-made high density thermoplastic polyethylene (HDPE) film as waterproof base material, on one side of HDPE film we cover with macromolecule self-adhesive film and on the exposed surface of composite adhesive phase we apply weather-resistant protecting layer and insulating layer. There is 75mm wide composite adhesive band for overlapping joint along longitudinal direction of the sheet material .

Advantage
1.PRE-APPLIED ENGINEERING
Pre-applied engineering for underground and tunnel engineering. After the waterproof layer is completed, the impact resistance of the steel-filled concrete without the protective layer is directly tied.
2.LOW BASE REQUIRMENTS
The base surface requirement is low, the construction period is saved, the base layer is not required to be leveled, and the wet base surface can be constructed; no need for the bottom layer and the base layer treatment, and it is not affected by the weather, which can save the construction period and reduce the construction cost.
3.SIMPLE CONSTRUCTION
The construction is simple and quick, the work method is flexible and diverse, and the wide-width membrane can be produced according to actual needs, achieving less overlap, quick construction, low consumption and low cost.
4．EMPTY PAVING
Construction can be selected according to the site conditions of the construction, such as empty paving, mechanical fixing, etc. The construction method is more flexible and the waterproof effect is better.
5.LOW TEMPERATURE FLEXIBILITY
Low temperature flexibility, throwing under low temperature conditions can maintain good flexibility.
6.EXCELLENT WATERPROOF PERFORMANCE
Excellent waterproof performance, has the advantages of the polymer waterproof membrane and the self-adhesive membrane.
Features:
Hot Weldable: Tight joint, leakage risk free;
High elongation break: Super adaptation to any structure ,breaking risk free;
Stick back : Excellent bonding performance, application as easy as pie;
Pre-application :Be part of the building foundation, no leakage risk, no maintenance needed;
ISO&CE authorized: Reliable quality, keep your project safe and sound;
Thorogh Pre-engineered system: Make detail treatment perfect& easy.
Application Pictures：
It can be widely used in underground projects such as basement, subway, tunnel, etc. It is especially suitable for waterproof projects with special environment and wet areas.

Procedures:
1.Clean the base layer. If there are sharp protrusions, it should be treated flat. If there is water obviously, the base layer is
allowed to be wet. Apply the cemntious Crystal Capillar coating on the pillar .

2. Spread the membrane. Make the membrane particles facing up, they are laid on the base layer. When laying adjacent membrane, attention should be paid to the alignment of the overlapping edges to avoid deviations affecting the overlap.
3.Membrane overlap. For long-side lap joint, uncover the separator on the side of the membrane and directly crush it. For short-edge lap joint, it is recommended to use double-sided self-adhesive tape for lap joint.
4. Cheacking if any damage or leaking areas and repair them. Slice the perimeter of damaged areas till 80mm larger, using the strong adhesive tape to amend it , with roller to press it evenly to shape it leaking free .
