: waterproof construction is the construction and home decoration two links of the play. It is understood that up to 46.5% of netizens think that the construction and home decoration process is the most headache is the problem of leakage of housing. Building waterproofing is related to building safety, long-term leakage will damage the building foundation, reduce building life. Building waterproofing is related to people's livelihood, leakage is difficult to solve, causing neighborhood problems, building waterproofing is related to building energy conservation, many doors and windows, external walls leakage, erosion of insulation materials, so that its thermal conductivity changes, reduce energy conservation; Building waterproof quality but often cause "house water" tragedy, how to improve the quality of building waterproofing, to solve leakage disease? How can the performance of waterproof products be well developed? This is worthy of developers and waterproof industry to think together and trade-offs, to find a solution to the problem.
currently 65% of new houses in China within one to two years will appear in varying degrees of leakage, leakage accounted for 65% of real estate quality complaints, ranked first. Sixty-five percent of building waterproofing projects need to be refurbished after 6-8 years, and building leakage has become the second largest construction problem outside the structure, long plaguing developers and owners.
reports show that 80% of China's buildings there is leakage, why so many new properties will appear leakage phenomenon? Through the investigation of the cause of leakage of buildings at home and abroad, the authorities found that the main cause of leakage is caused by improper construction operation. The results of the survey of the French Western Waterproof Company show that about 85% of the leakage caused by construction accidents, the british survey results caused by the leakage of water leakage also reached 70%, China's sample survey results are 48%. This means that improper construction is the main cause of leakage in construction projects. Even if the use of qualified waterproof materials and reasonable waterproof design, due to the construction process is not serious, poor construction quality, will still cause waterproof quality accidents. Therefore, ensuring the quality of construction is the key to improve the quality of waterproofing projects.
Waterproof industry has a saying "three points of materials, seven points of construction", materials only 30%, construction accounted for 70%, seven points of construction is controlled by people, often people are the most unstable factors, even if the material is good, construction is not good or a link out of the problem, leading to the failure of the entire system. And now the real estate development cycle is constantly shortened, many construction enterprises in the rush time did not follow the specifications to construction, so that waterproof operation has loopholes or the subsequent process to destroy the waterproof layer done in the early stage.
't finish talking about people, let's talk about material. Now the main control of housing prices according to local conditions, waterproof is no exception. Real estate development is very regional, but in recent years, many well-known real estate enterprises in the south into the north, the waterproof experience of the south transplanted to the north, will certainly be water and soil. Due to the rainy south, waterproof materials are mostly water-resistant materials, such as glass fiber tire, polyester tire modified asphalt coil or water-resistant adhesive adhesive bonding polymer coil. And the cold in the north, especially in snowy areas, some waterproof materials can not withstand the cycle changes of low temperature freezing expansion and contraction, premature aging fracture. Therefore, these areas should choose SBS modified asphalt coils or welded seam polymer coils. Secondly, different parts of the building, the requirements of waterproof materials are not the same, but also according to local conditions, according to the construction of materials.
because the roof waterproof layer exposed, sun and rain, wind and rain, so choose high pull strength, large elongation, anti-aging good waterproof materials. Wall leakage is because the wall is now too thin, mostly light masonry, there are a large number of internal and external seams, and then doors and windows Therefore, the wall waterproof can not use coils, can only use
paint
, and external decoration materials combined. Windowalso have sealing paste for the installation seams.
water-resistant layer is because of years of immersion in water or very humid soil, waterproof material must be water-resistant. The waterproof layer of the soleplate is thick and has a certain resistance to stabbing.
the toilet bath waterproof can not choose the coil, the coating is the most suitable, the paint and cement-based acrylate coating as the most suitable, can be firmly pasted on the tile.
addition, the choice of waterproof materials now also considers the need for building functions. For example, some roof planting flowers, green environment, because the plant root puncture force is very strong, waterproof layer in addition to corrosion and immersion, but also have anti-piercing capacity. In this case, polyethylene soil film (welding seams), PVC coils (welding seams), lead-tin alloy coils, and root-resistant modified asphalt coils should be used.
leakage is seriously affecting the quality of consumer housing, should cause the industry and related departments to pay attention to. Strengthening industry self-discipline and introducing relevant industrial policies are an extremely important part of promoting waterproofing of buildings and home installations.
