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:Foam concrete for the roof cushion generally do much bulk ah

Q:Basement floor mattress dry to what degree can do coil waterproof?

Third, the membrane waterproof in the construction should first do the basement floor of the waterproof, and then the membrane along the basement floor continuous paste to the outer surface of the wall. Basement floor waterproofing first in the foundation pouring C10 concrete cushion, the thickness of about 100mm. 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.

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.

Q:What is the difference between leveling and cushion?

Building floor cushion is the structure layer below the grass-roots level. Cushion as the name suggests is the structure of the liner layer, mainly plays the role of the back cover. Cushion should be noted with the basic distinction. It is easy to confuse the two engineering concepts.

Q:The top floor made waterproof playing cushion layer of how to do

Roof waterproofing can not use a single waterproof material, must be rigid and flexible combination of construction, flexible waterproof stretch is good, a little bit of settlement or deformation will not damage the waterproof layer. Rigid waterproof (ie mortar waterproofing agent) waterproof at the same time, can play a protective role, waterproof layer is not easy to be destroyed.

Q:Maintenance time of the cushion on the roof of the building

Concrete watering maintenance time: the use of Portland cement, ordinary Portland cement or slag Portland cement mixed with concrete, not less than 7d;

Q:Basement cushion waterproof

Third, the membrane waterproof in the construction should first do the basement floor of the waterproof, and then the membrane along the basement floor continuous paste to the outer surface of the wall. Basement floor waterproofing first in the foundation pouring C10 concrete cushion, the thickness of about 100mm. 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.

Q:Can the floor tiles be removed from the cement mats on the prefabricated board floor?

Prefabricated board surface is best to do some cement mortar cushion, can prevent the decoration of the water generated to the downstairs.
