WATERPROOFING MEMBRANE MANUFACTURER
Construction method and precautions of sbs bitumen waterproof membrane
The construction method of sbs bitumen waterproof membrane: Before construction of sbs bitumen waterproof membrane, the defects of the base layer should be cleaned up, and the moisture content of the base layer should not exceed 9%. The special base oil should be painted and fully dried before construction. The specific project construction and detailed structure should be carried out in accordance with the waterproof design, acceptance standards and construction specifications of the project.
1. The base should be dry, level, clean, free of dust, debris, oil, and moss. If there are holes, holes, 2. The cracks should be filled with cement mortar, and the protruding parts should be flattened.
3. For sbs bitumen waterproof membrane, apply the base treatment agent against the wind.

5. Lay the coiled material, exhaust and compact.
6. Paste the lap joints.
