Waterproof and breathable membrane roof engineering construction plan. Waterproof and breathable membrane (slope roof membrane) is suitable for various slope roof systems with and without purlins. It is laid on the insulation layer of the slope roof and combined with various roof tiles and metal plates. When used in combination with other materials, it can be used for roof waterproofing with level III and level II waterproofing.
.The waterproof and breathable membrane should be reliably fixed to the base layer. The overlap between membranes, the surrounding areas between the membrane and the structural base, and the detailed nodes must be tightly sealed and firmly fixed.
.The waterproof and breathable membrane used for roofing should be constructed under environmental conditions of ~℃. It should not be constructed in rainy days, snowy days and windy weather of level 5 and above. If it rains or is windy during construction, temporary fixing measures should be taken.
.If there are open flames or high-temperature operations at the construction site, effective protective measures must be taken for the waterproof and breathable membrane. Direct contact between open flames, welding operations or high-temperature objects and the waterproof and breathable membrane must be strictly prohibited.
.Waterproof and breathable membranes are divided into loose laying method and flat laying method according to the position relationship between the membrane and the water strip. When the lower layer of the drainage strip is not easy to be nailed (such as concrete or cement) and the flatness is difficult to ensure, the loose laying method should be used
That is, the waterproof and breathable membrane is laid between the tile hanging strips and the drainage strip. When the lower layer of the drainage strip is easy to be nailed (such as a wooden structure
), the tiling method is adopted, that is, the waterproof and breathable membrane is laid under the drainage strip
