Q:When the cushion is used, the thickness of the protective layer is not less than ()

Q:Is foam concrete suitable for use as a cushion?
And then through the foaming machine pumping system for cast-in-place construction or mold forming, the formation of natural conservation with a large number of closed pores of the new lightweight insulation materials.
Q:Can the cushion on the prefabricated board floor be dug?
Prefabricated board floor layer of cement layer is not called the cushion, should be called leveling layer, this layer can be removed, but be careful not to damage the prefabricated plate.
Q:Why do the basics of the cushion waterproofing
Base cushion waterproofing is not contact with the soil (Ying water) to prevent water into the cushion, but in the cushion and the base of the bottom of the contact, in fact, is the basis of the bottom of the waterproof.

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:Foam concrete for the roof cushion generally do much bulk ah
Foam concrete density grade is generally 300-1800kg / m3, commonly used foam concrete density grade 300-1200 kg / m3,
Q:The top floor made waterproof playing cushion layer of how to do
2. repair the cracks well. After the cracks to be repaired are dry, start waterproofing.
Q:Is it possible to make a waterproof layer
1, to do after the dry do, or prone to the phenomenon of wall skin off.
Q:Can the floor tiles be removed from the cement mats on the prefabricated board floor?
Cement cushion as a leveling layer on the floor, not designed to the structure of the load-bearing, the general can be dug, the cushion is generally 3 to 5 cm, chisel in addition to unloading the floor of the heavy objects, chisel in addition to the use of strong vibration Machine or penetrating machine is too large, with a small hammer small chisel, along the horizontal plane horizontal chisel, stripping cement cushion.
