Waterproofing membrane brand, Zhengzhou Oukai waterproof (certified), waterproofing membrane

 Waterproofing of underground engineering design criteria "underground waterproof engineering technical specifications" of the underground water engineering structures made special provisions Henan waterproofing membrane, provides as follows: (1) waterproof design of underground works should follow the "prevention, anti-row combination, the principle of local conditions, comprehensive management ". (2) water projects should be designed to follow the "anti-row combination," "positive side fortification" principle, and a "multi-channel fortification", "composite waterproof", "node seal" and other measures. Underground waterproof layer is the long-standing soaking water in a moist environment and water infiltration, and often there is a certain water pressure, waterproof layer buried in the ground with a permanent, non-replacement of necessary long-term durability. Steel roof waterproof construction methods and technology 1, sub-grid settings, and construction joints. Sub-grid should be set on the support side seam metal roof, the turning point of steel roofing, waterproofing layer and the prominent roof junction, and should align with the roof seams, waterproof layer due to the influence of the temperature difference, the drying shrinkage of concrete structural deformation waterproof layer cracks factors, concentrated in sub-grid joints, in order to avoid cracking of the board. Dividing joint set spacing should not be too large, when more than 6 meters, should set up a "v" shape in the central dividing joint waterproofing membrane plant, sub-lattice seam depth should be waterproof layer thickness throughout. When dividing joint doubles exhaust tract, joints may be appropriate to widen, and set the vent outlet when the roof with petroleum, asphalt, linoleum as a waterproof layer, sub-grid joints should be added to 200 mm to 300 mm wide linoleum, asphalt glue stick unilateral point, dividing joint embedded fill ointment. 2, roof leveling layer construction. Find slope roof with architectural and structural approach to find the combination of slope. 3, the construction of roof isolation layer. Zhengzhou local conditions in the construction waterproofing membrane from each other, the surface of this layer two cloth three oil waterproofing membrane made between leveling layer and a rigid layer, both played a role in the isolation layer waterproofing membrane, without being sun and rain, both to prevent aging ointment, waterproof underway. 4, the construction steel mesh and fine aggregate concrete rigid waterproof layer. In concrete waterproofing layer, should be equipped with two-way cold drawn steel mesh, and the sub-grid disconnect joints, stiffness and waterproof layer to enhance the integrity of the plate, steel mesh in the waterproof layer should be arranged as far as possible on the side site. The thickness of the protective layer steel mesh of not less than 10 mm.
