What is the material on the insulation layer on the waterproofing membrane?
3, the isolation layer before the use of paper gray or low-grade mortar, due to the construction of rigid layer, the pile of ash is easy to enter the concrete, so no. Low-grade mortar construction of the transport car on the waterproof layer of damage, and anti-slip performance is not ideal, so less used. Now generally use dry cloth linoleum together, but also useful thick plastic film and other materials.
2, waterproof layer on the other construction layer construction, it is possible to pierce the waterproof layer, the appropriate protection Is necessary, the isolation layer can also play a protective role.
The isolation layer of the roof waterproof layer is generally set between the waterproof layer and the above rigid protective layer, and he has two roles. 1, the surface of the rigid layer (usually 40mm thick fine stone concrete) will have thermal expansion and contraction deformation, if the waterproof layer and the rigid layer is very good, rigid layer deformation will affect the deformation of the waterproof layer, so there may be waterproof Layer to produce a direct cracking or long-term fatigue damage, so the two tectonic layers should be set with a sliding function of the isolation layer;
