Building waterproofing engineering has a great role in human life. Since ancient times, waterproofing and water control has been a major livelihood issue. With the advancement of technology and people's awareness of household waterproofing, building waterproofing engineering is also step by step. Rise to a new height. How to do the roof waterproofing project ? Next, let's take a look at the related content of the decoration home network Xiaobian!
First, roofing membrane waterproof
The waterproof membrane is mainly used for building walls, roofs, tunnels, highways, landfills, etc., and it can be used as a foundation for the construction of flexible building materials that can resist curling and groundwater leakage. There is no leakage connection between the building and it is the first barrier to waterproofing the entire project, which plays a vital role in the whole project.
The bitumen waterproofing membrane is a rollable sheet-like waterproof material which is formed by impregnating asphalt on a base tire (such as base paper or fiber fabric) and then spreading a powdery or sheet-like insulating material on the surface.
Second, the roof coating film waterproof
Waterproof coating refers to the application of water-repellent liquid paint on the screed of roofing or underground buildings. Commonly used waterproof coatings are asphalt based, chemical by-products and synthetic resins. Roofing film waterproofing can be divided into three categories according to performance:
Flexible waterproof roof: all kinds of waterproof membranes, waterproof coatings, sealing materials, etc. Flexible high-elastic waterproof coating is a double-combination, propylene-based polymer modified cement-based waterproof coating composed of high-grade cement with high polymer and selected additives and liquid polymer additives, powder and After the additives are mixed, a chemical reaction occurs to form a tough elastic waterproof membrane. The membrane has good adhesion to concrete and mortar, and can form a tight and firm permanent bond with it, preventing water from penetrating.
Rigid waterproof roof: structural self-waterproof concrete, waterproof mortar and so on. The rigid waterproof layer can directly paste the exterior wall finishes such as strip bricks and paper bricks, or directly apply the putty powder as the exterior wall finish. It has strong adhesion to concrete, masonry and other substrates, stable volume, prevention of cracking, strong impermeability of the coating, and can be used for waterproofing on the water surface. It can be directly applied on the wet base.
Composite waterproof roof: flexible waterproof and rigid waterproof combination. Composite waterproofing is a concept proposed by modern building waterproofing. It combines flexible waterproofing and rigid waterproofing to make the waterproofing project more adhesive, stable, environmentally friendly and convenient. It is especially suitable for the construction of modern building waterproofing engineering.
