4. The basic color of the coating film is white, and various colors can be painted on the surface of the coating film, and various colors can also be made according to user requirements to achieve waterproof decorative effect.
5. The anti-leakage sealant can be made by adding rubber powder, sand is added to make the anti-slip layer, and light hollow fillers can also be added to make the thermal insulation coating.
6. It is easy to use and maintain, saves labor, saves time, saves money and is safe.
1, the importance of waterproof technology
The quality of waterproofing projects will directly affect the length of service life of buildings and structures, affecting the normal production. For a long time, due to many reasons such as design, material selection, construction, settlement, and deformation, the waterproof project is very serious. Leakage problems such as roofing, toilets, exterior panel panels, and basement leaks have become common problems in the quality of waterproofing projects. These quality problems lightly caused the roof and the cornices to be exfoliated. The heavy groundwork could cause flooding of underground projects, and even the settlement of buildings could be deformed to form dangerous buildings, endangering people's lives. In addition, the cost of waterproof construction projects generally accounts for about 15% of the total cost of a single-story industrial plant. Normally, half of the maintenance costs for buildings are used for leakage maintenance. Therefore, waterproof construction must be standardized, standardized, and scientific, and quality must be ensured. Exert capital investment results.
2, the main cause of leakage problems
(1) Material properties and quality
The quality of waterproof construction depends mainly on the performance and quality of the waterproof material. The traditional waterproof layer method mainly uses petroleum asphalt or mastic resin to bond paper-grade tire bitumen felt, which is generally a two-layer, three-oil and five-layer practice. This material has low temperature brittle fracture, high temperature flow, low tensile strength, easy cracking, aging and other issues. Due to the short life span, it is generally about 5 years, and even some of them leaked during the year. Therefore, the performance and quality of the material itself is an important cause of leakage.
(2) Construction quality
Poor construction quality is another important cause of leakage. For example: due to uneven grass-roots level, so that the waterproof layer of water, long-term moisture to make the paper mold rotten;
The improper selection of materials, such as the marking of petroleum asphalt is not used according to the requirements of the specification, the formulation of mastic is not allowed or even unmatched, resulting in low temperature brittleness and high temperature flow.
The lack of detail work is the main cause of leakage during operation. In particular, it is not appropriate for waterproof structures such as drain outlets, parapet walls, cornices, telescopic rakes, pipe roots, and plate joints, and the rigidity of aerated concrete roof panels is insufficient. Collapse of water and other factors;
Failure to pay attention to finished product protection and destroy the waterproof layer is another cause of water leakage.
Rigid waterproof roof with low anti-seepage mark causes water seepage.
(3) Problems of settlement and deformation
Uneven roof stress or building settlement, structural deformation, or earthquake disaster, tearing the roof of the waterproof layer caused by leakage.
(4) Design issues
Poor design is also a factor that causes leakage. If the slope of the roof is too small, the drainage is poor and the waterproof structure is leaking.
