Q:Roof waterproof mattress should play the number of centimeters appropriate
  2. repair the cracks well. After the cracks to be repaired are dry, start waterproofing.
Q:Is the raft cushion waterproofing full of the cushion?
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 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).
Q:Why calculate the amount of time to count a lot of cushion ah
  In the municipal engineering, the bedding layer is a structural layer between the grassroots and the soil foundation. When the soil temperature is bad, the water temperature of the soil is improved and the water stability and frost resistance of the pavement structure are improved. Diffusible load to reduce soil deformation.
Q:Basement floor mattress dry to what degree can do coil waterproof?
First, the basement moisture treatment structure is usually: first in the basement wall outer surface wiping 20mm thick 1: 2 waterproof mortar, basement walls should be used cement mortar masonry, gray seam must be full; and in the basement floor and the first Floor floor is divided into two walls of the level of moisture-proof layer. The outer wall of the basement wall should be tampered with the soil with poor permeability.
Q:What is the difference between leveling and cushion?
Commonly used materials are, cement mortar leveling layer, fine stone concrete leveling layer, asphalt mortar leveling layer and so on. Leveling layer and the difference between the cushion, which is a very easy to confuse the two engineering concepts.
Q:How to build a fine stone concrete cushion?
The cushion is primarily responsible for the load coming from the surface and passes the load evenly to the structural or base.
Q:Foam concrete for the roof cushion generally do much bulk ah
in recent years, the density of 160kg / m3 ultra-light foam concrete is also used in construction projects.
Q:Do you need a cushion on the ground floor?
As well as the time to build a wooden building with concrete pier, from the ground or contact the ground to do a good job preserving.
Q:Why do the basics of the cushion waterproofing
Raft foundation do not do waterproof mainly depends on the design of the groundwater level considerations, calculated if the floor itself to meet the requirements, you can not do, and not rigid to do
Q:What is the relationship between the cushion and the ring beam?
Ring beam is reinforced concrete. Is to increase the overall wall and overall stiffness, improve the side resistance performance, according to the earthquake or masonry specifications set. There may be in the ground wall, there may be in the underground wall.
