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".

3)Key Features of ceiling roof material
- Q: How to ensure the waterproof quality of the underground shear wall (retaining wall)?
- 2, when the basement depth is large, it is impossible to dig a place in time, you can use the reverse construction method, that is, dig a certain depth, then finished a section of retaining wall, to be a certain strength, and then open Dig, do the next retaining wall, and in this order until the construction to the specified design depth.
- 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: Waterproof mortar expensive or dry mortar expensive
- Waterproof mortar more expensive. Because waterproof mortar compared to dry mortar, to add another waterproofing agent, emulsifier and other substances. Waterproof mortar regardless of the cost or transport are more cost-effective.
- Q: What material waterproofing can be mixed with cement sand
- Construction can be made with the waterproofing agent and cement made of waterproof mortar. The ratio of cement to sand is 2: 3, and the amount of waterproofing agent is 1% of the cement.
- Q: Hello, roof with SBS waterproof material bulk density is how much?
- As the SBS coil finished with pure asphalt is not the same, the coil includes a variety of surface material weight. The following is the different types and different thickness of the SBS coil unit area weight, due to the need to lap and pave the reinforcement layer, calculate the load in the following unit area weight, the general multiplied by 1.2 coefficient.
- 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: Roof leakage, what materials do the best waterproof
- hird, for some of the city building cover the construction of red tiles leakage, as long as the removal of tiles on the grass, moss or dust after the replacement of tiles, leak-proof effect is the same. For flat roofs, the roof of the obvious cracks, with the tool will be cracked into a "V" or "U" shape, filling the caulking ointment, filled with cracks and above the use of waterproof wrap around the package. To strengthen the leak-proof effect, you can also shop a layer of waterproofing membrane. 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.
- Q: I would like to ask how to do in the warm water above,
- 1, I think the flexible mortar, waterproof paint better, because these materials in the construction process, not to warm the temperature caused too much impact, if the shop waterproofing membrane is too heavy, may affect the warm heat. 2, generally in the floor before the warmth, first do a waterproof, paved to warm to do once.
- Q: Why should the use of high pressure perfusion waterproof plugging method
- High pressure grouting construction principle: is a special high-pressure grouting waterproof material through the high-pressure infusion equipment into the concrete crack structure extended until all the cracks (including the naked eye is difficult to meet) filled with water (water) with the cross-linking reaction, Release a large number of carbon dioxide gas, resulting in secondary pressure, high pressure and secondary pressure will be pressed into the elastomer and filled with all the gaps, to stop the purpose of leakage, it can be said that the best performance of plugging material,
- Q: Rigid (concrete) waterproof roofing shop SBS coil can brush a layer of waterproof paint before?
- Second, the completion of the construction of the membrane and the acceptance of qualified, should do the protection of finished products, it is recommended to use cement mortar to do protective layer, construction should pay attention to the surface should be smooth pressure, and set the surface sub-grid, 1 m2. If the use of block material to do the protective layer, the sub-grid area should not be greater than 100 square meters, sub-grid width should not be less than 20mm; if the use of fine stone concrete protective layer, the sub-grid area should not be greater than 36 square meters. Note: Regardless of which protective layer is used, a separation layer should be provided between the waterproofing layer and the protective layer.
