         1、 Roof waterproof engineering is one of the components of building waterproof engineering, generally refers to the roof waterproof construction, but also includes the roof insulation engineering. It is composed of roof leveling layer, air barrier layer, thermal insulation layer, waterproof layer, protective layer and surface layer. The quality of its construction will directly affect the service life of the building.




2. The roof can be divided into flat roof, sloping roof and special-shaped roof according to its form; it can be divided into non accessible roof and accessible roof according to its use function; it can be divided into thermal insulation roof and non thermal insulation roof according to its heat insulation function.


Thirdly, the waterproof engineering of roof can be divided into rigid waterproof roof and flexible waterproof roof according to the different properties of waterproof materials.

1) it is forbidden to carry out waterproof construction and thermal insulation construction in rainy days.
2) the leveling layer of the membrane waterproof layer shall meet the quality requirements and reach the specified drying degree.
    3) In the roof corner, gutter, gutter, roof ridge, coil lap, end and other node parts, it is necessary to carefully pave, compact, close firmly, meet the design requirements and roof waterproof engineering technical specifications and other relevant provisions. Of course, if spraying rapid setting rubber asphalt waterproof coating and other products are used, the coil lap joint, end and other node parts will not exist, and the roof turning Corner, gutter, gutter, ridge and other parts should be strengthened with additional layer.

4) the waterproof layer shall be protected when laying the insulation layer.


The following are matters needing attention in the construction of waterproof coiled materials, such as spraying liquid rubber coatings can be ignored.
1) avoid excessive tension and wrinkling during the paving of waterproof coiled materials. Exhaust air between the base course and the coiled materials should be sufficient. After exhausting air to both sides of the horizontal direction, use rollers to flatten and paste.

2) the overlapping width and paving of waterproof coiled materials shall be straight, and the construction shall be carried out in strict accordance with the marking lines marked on the base course. Jiangsu Xinda waterproof and plugging
