With the continuous development of China's construction industry, waterproof materials and construction methods are also constantly improving and innovating in the building waterproof industry.
In recent years, various building waterproof enterprises have also introduced their own ideas and waterproof systems in terms of material production and construction methods for building waterproof.
Zhongtong Waterproof Co., Ltd. is launched in combination with years of production and construction experience “ Good self energy effect, maintenance free waterproof system ” , providing protection for buildings. The system Aiming at the problem of building leakage and the problems in the process of traditional sheet material and waterproof construction, the new technology is sublimated in technology, formation Water tight, maintenance free and low cost Complete new concept of building waterproof.
• As we have done waterproof engineering for many years, we all know that new buildings often leak water within two or three years. The waterproof layer of the building often needs maintenance. Even if the first level waterproof is adopted, there will be water leakage.
• So is there a waterproof method that can avoid such problems and ensure that the building will not leak for a long time? Zhongtong waterproof "good self energy effect, maintenance free waterproof system" is such a kind, Water tight for at least 30 years Waterproof system.
What is the new construction method What about the "maintenance free waterproof system with good self performance"? Zhongtong waterproof "good self energy effect, maintenance free waterproof system" ， Generally, spraying (scraping) is adopted Uncured rubber asphalt Waterproof coating ， Paste One It is a composite waterproof construction technology composed of elastomer modified asphalt coiled material, self-adhesive polymer modified asphalt coiled material and polymer sheet.
Why is this construction process called “ Good self performance, maintenance free ” What about? “ Self energy ” It means that the system can realize self repair of waterproof layer when the structural layer changes or external damage occurs within a certain range. “ Good effect ” Just yes coating Matching with coiled material, combined with the advantages of coating and sheet's own physical properties, to achieve close bonding with the building structure without gaps, this combined waterproof achieves 1 1>2 Waterproof effect.
“ New construction method ” It is machined, spray The construction method can greatly avoid the influence of human factors on the performance of waterproof layer during construction. Greatly improve the construction efficiency, give play to the material performance, and save the construction cost. This system is self-healing and adaptive to avoid repairing the waterproof layer again after construction.
You can see clearly through the pictures
The bottom layer is a non curing rubber asphalt waterproof coating with high adhesion, high extensibility and creep self-healing properties, and the surface layer is polymer modified asphalt Waterproof roll It has high degree, high toughness, tear resistance and crack resistance, and has strong applicability to base course expansion and cracking deformation in practical application. It can be seen that the secret of this system is to realize the close connection between the base course and materials, and between materials without gaps, eliminate the water channeling layer, and form a whole waterproof layer and the building.
After undertaking the project, Zhongtong Waterproof decided to adopt “ Good self energy effect, maintenance free waterproof system ” Non curing rubber asphalt waterproof coating and SBS Modified asphalt waterproof coiled material.
Non curing rubber asphalt waterproof coating It is a waterproof coating made of rubber and asphalt as the main components, adding additives, and maintaining a sticky paste within the service life. This kind of coating can seal the cracks in the base course, adapt to the complex construction working surface, and will not solidify for a long time after contacting with the air, with strong self-healing ability and adhesiveness. It can solve the fracture of the waterproof layer caused by the crack of the base layer and the stress transfer to the waterproof layer. The creep material enables it to well seal the pores and cracks of the base layer, solve the problem of water channeling of the waterproof layer, greatly improve the reliability of waterproof, and also solve the compatibility problem when the existing waterproof coiled materials and waterproof coatings are used together.
Non curing coatings can effectively self repair damaged parts. When the waterproof layer is punctured by external force, the damage point will not expand, and water channeling will not occur at the bottom of the waterproof layer. Moreover, the creep property of the material will heal slightly, which improves the reliability of the waterproof layer and reduces the project maintenance cost.
