Pre-applied Self-adhesive Waterproof Membrane-Self-adhesive Waterproof Membrane-HUAGUANG SINORGCHEM WATERPROOF MATERIALS LIMITED BY SHARE LED.

PRODUCT OVERVIEW

The pre coated polyester self-adhesive waterproofing membrane with asphalt based polyester waterproofing membrane as the main material (add functional additives), both sides are coated with a layer of self-adhesive, self-adhesive waterproofing membrane and attached coated silicon film can be stripped and made as the isolation material.

PRODUCT FEATURES

1. cold construction: do not use naked flame, no adhesive, energy saving, environmental protection, low carbon, economy;

2. high tensile strength, elongation, resistance to puncture, corrosion resistance;

3. coil and after pouring concrete bonding as one, even in the long-term immersion of water is also inseparable, completely eliminate the channeling water, may be more robust waterproof performance;

4. waterproof coil and the base are not bonded, construction is not affected by the grass-roots and environmental humidity;

5. wide coil material construction, less loss, construction more convenient.

To adapt to the scope of

The utility model is suitable for waterproof of the basement side wall of the floor of the station and the construction method of the exterior prevention and the inner lining method of the underground construction and the open excavation method; the waterproof of the non exposed roof project is particularly suitable for waterproof engineering which can not be used by naked fire.
