AI Technical Summary
The existing roof waterproofing structure has poor weather resistance, is prone to leakage at the joints, the insulation layer is prone to water accumulation and expansion, and the junction of the waterproofing layer and the parapet wall is not fixed, resulting in a high risk of water seepage.
The lower waterproof layer is embedded in the groove of the parapet wall, and the upper waterproof layer covers the parapet wall coping. The waterproof membrane and waterproof coating are combined to form a composite waterproof structure. The vent pipe is pre-embedded in the insulation layer. The structural layer is made of high-strength concrete, the insulation layer is made of a combination of extruded polystyrene board and rock wool board, the protective layer is made of fine stone concrete, and the surface layer is made of EPDM plastic.
It significantly reduces the risk of leakage, extends the service life of waterproofing, improves the durability of the insulation layer, enhances the reliability of waterproofing, prevents thermal bridging, and improves the overall stability and aesthetics of the roof.
