What is the separation between the roof waterproof protective layer and the waterproof layer?
That is, at home and home boundaries to break off. Or can not achieve the effect of waterproof
It is necessary to set the isolation layer to prevent damage to the waterproof layer
The meaning of the protective layer and the isolation layer is not the same, figured out the role and meaning of nature know how to set up. 1, the protective layer of the waterproof layer contains a two-tier meaning. First, if there are other waterproof layer above the construction layer, due to the construction process may cause damage to damage to water, so need to do protective layer; Second, the roof is the function of the master or planting, the activities of personnel may cause damage to water , Need to do protective layer. 2, the role of the isolation layer is also divided into two kinds. First, to prevent the adverse effects of the two kinds of materials (incompatible), with the isolation layer for the interface, such as PVC coil and polystyrene foam insulation board, because the plasticizer in the membrane will migrate , The direct contact with the benzene plate will produce melt damage; Second, the coil surface of the rigid layer, may be due to thermal expansion and contraction deformation affect the waterproof layer, in the rigid layer of the larger part of the deformation, Too large and damage the waterproof layer, then need to set the isolation layer. There is a geotextile isolation layer between the waterproofing membrane and the pebble press material. 3, not all of the waterproof layer and the protective layer between the need for isolation layer. When the cement mortar is used as the protective layer, the cement mortar may be directly applied to the waterproof surface. When the flexible protective material (heat reflective coating, etc.) or the insulation layer is used, the isolation layer is not required.
