FAQ

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.

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;

Do you need a cushion on the ground floor?

In addition to wood also buy wooden side, used as the main beam, beam and pillars. The ground is also recommended to raise, raise the place also to beam and pillars The number of boards to be based on your design to determine the ground practice, roof practices will affect the number of wood

And then paste the membrane, and then in the coil to wear 20 thick 1: 3 cement mortar, and finally pouring reinforced concrete floor. The outer surface of the wall first wip 20mm thick 1: 3 cement mortar, cold base oil, and then paste the membrane, the membrane should be stitched paste, adjacent coil lap width of not less than 100mm. The top of the coil should be higher than the maximum water level of about 500mm, the outer side of the brick wall.
