Q:Roof waterproof mattress should play the number of centimeters appropriate
Roof leaking of the construction program:   1. Need to remove the previous waterproof, such as paint, coil, etc., if it is to do the mortar waterproof can not be eradicated.
Q:What is the waterproof layer and the waterproof cushion in the tile roof?
Waterproof layer: set in the tile or metal sheet below, from the waterproof, moisture-proof structure of the layer. The waterproof cushion plays an important role in the tile surface, because the "tile" itself can not be counted as a waterproof material, only tile and waterproof cushion combination to form a waterproof fortification.
Q:Is foam concrete suitable for use as a cushion?
Inappropriate. Bubble concrete is a new type of energy-saving and environmentally friendly building materials, which are widely used in wall materials, but there are still some defects, such as low strength, cracking, water absorption, as the cushion of its strength is not enough standard.

The outer wall of the basement wall should be tampered with the soil with poor permeability.
Q:Why do the basics of the cushion waterproofing
The general basis of the foundation, the bar base is not necessary to do, like a raft in the basement, it is necessary to prevent the water from dipping into the basement (so the basement design may have to do anti-floating calculations). Assuming (just suppose) the raft can easily turn over, then we do waterproof (like roof) directly on it, not waterproof on the cushion.
Q:The cushion is usually in the housing which parts
There was no other place in the house below
