Product Description:

1) Introduction of  breathable membrane for pitched roof

  1.    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

  2.    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.

  3.    Breather membrane may also serve as an air barrier if it is sealed carefully at seams.

  4.    Breathable Membrane have good "water resistance", good "water vapor permeability", and good "air barrier properties".

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
Second, if the roof is only the original did not do waterproof, only need to remove the leaky parts of 2 ~ 3cm deep after cleaning, you use asphalt irrigation, and now there is finished asphalt coating, such as sunny day when the treatment will basically not Leaked out. If there is a waterproof layer is too much trouble, to be around a range of waterproof tick, re-do waterproof, do when the attention and the original waterproof junction to do reinforcement layer. There are many ways to deal with leak detection, or to find some professional leak-proof companies to deal with this problem.
Q:Slope roof drains do not need to be waterproof
The overall rigid waterproof layer is often due to these small structural nodes handled properly, resulting in the failure of the entire roof waterproof.
Q:Waterproof material water leakage construction should pay attention to what
2, wall treatment · Wall treatment to do about 300mm high waterproof coating, to prevent water infiltration wall back tide. · Bathroom between the wall and the ground (plane and elevation) brushing height should be greater than 100mm. · The height of the shower room in the bathroom is not less than 1800mm. · If there is a bathtub, the height of the wall adjacent to the bathtub should be 300mm higher than that of the bathtub. · Waterproof height of tub is not less than 800mm. · The height of the squat should be more than 900mm. For the transformation of the toilet wall and self-built light wall, the proposed height of the waterproof to do the top.
Q:Finished house bathroom waterproof household acceptance should be how to accept?
2: waterproof layer should be extended from the ground to the wall, 250mm above the ground. Bathroom wall waterproof layer height of not less than 1800mm.
Q:Eastern rainbow waterproof how to do
Do not know where you use, waterproof as if a lot of materials. I know there are coiled, painted.
Q:How do you make waterproofing in the kitchen and bathroom?
Fatty acid cement mortar waterproofing agent; integrated current domestic and foreign new waterproof material of the latest technology, in the original polymer cement mortar waterproofing agent developed on the basis of raw materials imported from Germany, the higher fatty acid materials, by more than 20 kinds of raw materials by the special complex Chemical reaction of water-based emulsion, a new type of fatty acid cement mortar waterproofing agent.
Q:Bathroom first leveling or do waterproof, what is the difference
2. Grass-roots waterproof, materials, local conditions, with particular attention to the wall and root and other vulnerable parts of the leakage, should do some special waterproof, plugging treatment. Stir the waterproof material, the first layer of the coating should be waterproof material scraper evenly coated on the base surface, the thickness of 0.6mm or more, to be uniform, the first wall after the operation, from the inside out of the operation , Can not have local deposition, leaving no bubbles, strong bonding. Ground waterproof layer should be painted out of the bathroom door outside the 300 wide, should be higher than the ground 200, shower wall waterproof layer should be higher than the ground 1800mm. The next brushing direction is perpendicular to the last time. The last time the film semi-curing, throwing coarse sand particles, easy to combine with the cement mortar in the future. To be dry after a few days to do closed water test, observe no leakage side good.
Q:Can Henkel have water against him?
In order to ensure the quality of the proposed do not add water, the general finished materials are proportional, emulsion and powder, in strict proportion.
Q:Find the construction steps for waterproof coatings
3, note (1) rain weather and five wind above the weather shall not be construction. (2) coating waterproof layer shall not have bottom leakage, cracking, holes and other defects and peeling, bubbling, carcassing and wrinkle phenomenon. Coating waterproof layer and the base should be bonded between the solid, no hollowing, trachoma, delamination and so on. (3) the coating site should be continuous, solid, shall not appear Alice, hollowing parts. (4) rigid protective layer before the completion of any personnel shall not enter the construction site, so as not to damage the waterproof layer; coating of the overlapping parts should be care by the staff. (5) roof should be used lime soil, clay or sub-clay for backfill, thickness 50 cm, backfill shall not contain stones, gravel, ash and organic matter. Artificial compaction of each layer 25 cm, mechanical compaction of each layer 30 cm, rammed to prevent damage to the waterproof layer.
