Q:Is it possible to make a waterproof layer
2, waterproof layer: In order to prevent the rain into the roof, groundwater into the wall, basement and underground structures, indoor water into the floor and walls and other materials layer.
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:What is the difference between leveling and cushion?
Cushion, the base material is not divided into materials at the same time, the design will be described. Material is the same concrete, the greater than 20CM calculated basis, less than, equal to 20CM calculated cushion. Leveling layer refers to the original structure due to the existence of uneven or slope and the laying of the base layer, is conducive to laying the surface layer or waterproof, insulation layer. The role is to play a leveling, looking for a slope or enhanced function.
Q:Foam concrete for the roof cushion generally do much bulk ah
First help you correct it, foam concrete used in the roof should be the role of thermal insulation, not as a cushion.
Q:The roof cushion is waterproof on the slope roof
When the moisture generated by the ice dam into the external walls of the gap, the walls and insulation layer will become damp, which is the ideal environment for the breeding of mold.
Q:When the cushion is used, the thickness of the protective layer is not less than ()
Master roof: the general use of 40 thick C20 reinforced fine stone concrete protection.
Q:Can the floor tiles be removed from the cement mats on the prefabricated board floor?
Cushion generally no steel mesh, even if there can be removed, it is used to inhibit the cushion cement mortar layer cracking.
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:Is foam concrete suitable for use as a cushion?
The foamed concrete is a foaming system through a foaming machine that allows the foaming agent to be fully mechanically foamed and the foam is mixed evenly with the slurry.
Q:How to build a fine stone concrete cushion?
Reduce ground cracking, plus steel mesh. Reinforced mesh, should be placed in the middle of the concrete, because the protective layer of concrete thick Fang generally only 5CM thickness, so the middle is the best.
