1) Introduction of ceiling roof material

Breathable Membrane is a water resistant membrane but with high vapour permeability, use as diffusion open roofing felts under pitched roof tile or vapour permeable barrier housewraps on timber frame walls
Breather membrane functions as a weather-resistant barrier, preventing rain from getting into the roof or wall assembly while allowing water vapor to pass to the exterior.
Breather membrane may also serve as an air barrier if it is sealed carefully at seams.
Breathable Membrane have good "water resistance", good "water vapor permeability", and good "air barrier properties".

Q: Bathroom first leveling or do waterproof, what is the difference: 5. backfill rough flat mortar leveling, and its slope and do waterproof with the grassroots level and grass-roots waterproof, not tired. But pay special attention to this layer of closed water test (for most of the lack of toilet in the ground) is more important. 6. The surface layer and the adhesive layer, requires the slope has been done to slope or squatting, wall tiles to cover the tiles, reduce water into the wall.

Q: What decoration materials, light and water, and the wall, the perfect combination of glass: Second, cover the surrounding surface With the tape or the US profile of paper to cover the surface of the interface surface, according to the width of the gap to keep the gap width, width uniformity to ensure that the sealing of the work lines neat and perfect;

Q: What material is used for waterproofing of tarpaulin: Regardless of the construction or finished products are toxic, due to organic materials, it will form a separation layer, partition structure of poor wear resistance, must be a protective layer of solid, not hollowing, but requires the base surface moisture content of less than 8% overlap requirements No interface to form a seamless body thickness control easy to control the local thickness difficult to control

Q: Roof membrane waterproof construction process, what should be noted that?: Foundation treatment to find leveling to pay attention Five to: 1 slope accurate, smooth drainage 2 surface is flat 3 strong 4 clean 5 dry

Q: Hello, roof with SBS waterproof material bulk density is how much?: Similar to styrene-butadiene rubber, SBS can be in contact with water, weak acid, alkali, etc., with excellent tensile strength, surface friction coefficient, low temperature performance, excellent electrical properties, good processing properties, as the current consumption of the largest thermoplastic Elastomer.

Q: There is no formaldehyde in the finished putty: The current status of the market to buy regular manufacturers out of semi-finished products putty and formaldehyde has nothing to do, because the status quo countries also hit the product containing formaldehyde in the building materials, the current market traffic is relatively large for the water putty, putty powder which is natural mineral powder And water-based glue synthesis, because the product life long-term pollution-free, so that is impossible to contain formaldehyde, but engineering putty is usually on-site modulation, and in order to increase the adhesion of putty powder inside the addition of a large number of construction glue (Containing formaldehyde).

Q: What should you pay attention to before the construction of the basement waterproofing membrane?: 2, the mold of the nail set: in accordance with the pre-scheduled area along the painted bottom line nail with polyethylene film wrapped wood mold. Mold to be flat, with the basic nail implementation, to prevent leakage material.

Q: Why should the use of high pressure perfusion waterproof plugging method: Due to uneven settlement of buildings and other factors, resulting in deformation of the building structure cracking, leakage phenomenon, for the repair of this situation, you can use a new foreign plugging construction technology - high pressure grouting waterproof repair technology.

Q: Villa roof leakage what general reasons, what materials to remedy: ??Note: Before the waterproofing and draining construction, the roof must be dry, because the roof of the water does not evaporate, the new waterproof layer will rise, the waterproof effect immediately invalid. Therefore, rainy days should not be construction, to wait until the sun will dry the water before construction.

Q: What is the difference between finished mortar and cement mortar?: Finished mortar and cement mortar difference: Cement mortar is the synthesis of three main materials, cement, sand and water, and mixed mortar is the synthesis of four major materials, cement, sand, lime and water.
