    Product Technical Requirements

    ◆ The surface of the waterproof membrane should be free of bubbles, scars, cracks, adhesion and holes.

    ◆ The top surface of the N-type waterproof membrane is embossed into a grid pattern to enhance the bonding strength between the waterproof membrane and the concrete. The specifications of the grid pattern are: embossing height 0.1±0.02mm, 25~30 pieces/cm2.

    ◆ L-type waterproof membrane should be double-sided hot-melt composite non-woven fabric, the width of the non-woven fabric not composite at the lap joint is not more than 80 mm.

    Product Features

    Due to the saturation of the chlorinated polyethylene molecular structure and the introduction of chlorine atoms, the main chain is not easily broken under the action of oxygen, ozone, sunlight, moisture and heat. Therefore, chlorinated polyethylene waterproof membrane has excellent
    aging resistance, ozone resistance, oil resistance, high strength, high elongation, long service life, light weight, easy construction and maintenance.

    Application Scope

    Suitable for waterproofing projects of railway bridges and other types of building facilities.
