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: A complete set of basement waterproof construction program: Second, the basement of the external walls of water leakage construction preparation 2.1 Technical preparation 2.1.1 Selection of construction methods Waterproof engineering is related to the use of the project an important indicator, it is the construction process of a key project, difficult engineering. The choice of construction methods and programs has a direct impact on the quality of construction. The underground wall of the project SBS waterproofing membrane with hot melt method full construction. 2.1.2 before the start of the project, the first organization of engineering and technical personnel to enter the construction site, to understand the situation, to further understand the characteristics of the project to solve the contradiction between the construction technology and the implementation process. 2.1.3 technology before the end of the construction of waterproofing works by the professional foreman in accordance with the construction drawings and the existing national norms require the actual situation of the project to the construction team in writing to the end. The contents include construction site, construction sequence, construction technology, construction level, node fortification method, enhancement site and practice, project quality standard, guarantee the quality of technical measures. And after the field technical person in charge of the strict implementation of the audit.

Q: Waterproof mortar expensive or dry mortar expensive: Cationic neoprene latex is a polymer modified polymer anti-corrosion system. By the introduction of imported epoxy resin modified latex by adding the domestic neoprene emulsion and polyacrylate, synthetic rubber, various emulsifiers, modified latex and other components of the polymer latex.

Q: How does the finished ventilator manufacturer waterproof?: Rooftop natural ventilator waterproofing measures are mainly two kinds, one is the traditional silicone, adhesive tape waterproof, the other is the structure of water, the national standard Atlas 11CJ33 "ventilation and light skylight" recommended the use of structural waterproof technology.

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: Js waterproof coating without powder can brushing: 5. Coating maintenance: JS cement-based waterproof emulsion coating construction after 24 hours after the end with a damp cloth to cover the coating or spray water to maintain the coating, usually 2-3 days; air humidity, poor ventilation of the local dry The time period may be longer, and vice versa; 6. Check the construction of JS waterproof coating (closed water test): bathroom, pool and other parts in the JS cement-based waterproof emulsion waterproof layer after dry (at least 24 hours in summer, at least 48 hours in winter) stored water for 48 hours to see the water Construction is not qualified. Light wall must do the water test. JS waterproof coating See the amount of: under normal circumstances, the amount of about 0.6-1kg / ㎡, the actual amount from the use, the use of parts, rough surface roughness, environmental factors such as the decision.

Q: There is no formaldehyde in the finished putty: In addition, the addition of redispersible latex powder in the putty powder will make the putty have stronger adhesion and mechanical properties, outstanding water resistance, permeability, as well as excellent alkali resistance, abrasion resistance, and can improve water retention Sex, increase the opening time, enhance the durability.

Q: What should you pay attention to before the construction of the basement waterproofing membrane?: 5, plastic runway laying completed, maintenance and maintenance 7 to 10 days before they can be used normally.

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: Waterproof material water leakage construction should pay attention to what: 3, do the closed water test After the waterproof construction is completed, the water storage test. Will be blocked all the toilet outlet, the door at a pound of about 200mm high barrier, and then poured in the bathroom about 20mm ~ 30mm deep water, and 24 hours after the inspection of the walls and the ground around the leakage phenomenon , Waterproof test is to ensure the quality of the bathroom waterproofing the key, we must do. Such as after 24 hours without leakage as qualified. If you find a leak, you should immediately stop the water storage test, re-waterproof layer to improve the treatment, after passing the water test.
