FAQ

Large area ground concrete cushion seam Why is the separation of joints generally concrete

First, the rigid waterproof layer in a large area of ??construction, by the external force, temperature, humidity changes, structural layer deformation and other factors prone to cracking, leading to leakage, the design should consider the deformation of the waterproof layer to take the necessary Structural or structural measures to avoid and mitigate the cracking of the waterproofing layer to achieve the desired waterproofing effect.

What is the difference between leveling and cushion?

Cushion is generally used in the ground floor of the building, leveling layer is generally used in the floor or roof. According to the above analysis, I believe that we use the quota, where the floor, roof construction, it should be used to find the level of the fixed sub-head, because there is no so-called concept of the cushion, leveling layer thickness is not what Specific provisions can also be used at the same time different layers of leveling, but must be carried out in accordance with the design requirements, so as not to exceed the load;
