Building roof waterproof construction is an important link of the whole construction engineering project construction, if the waterproof technology is not mature, improper application of waterproof measures, will cause the roof leakage, affect the service life of the building, therefore, must to do a good job of waterproof.

1. Waterproof construction measures for coated waterproof roof

Coating, waterproof construction technology is to coating above the base of the roofing waterproof coating, after curing will be in the form of basic level surface with a certain thickness of elastic coating whole, thus to achieve the effect of waterproof. Because this waterproof construction measure is simple and feasible, and has certain economy, it is widely used in roof waterproof.

Basically, the roof of a building can adopt roll coating method, but for small areas such as floor drain, it is necessary to apply paint brush. It is necessary to ensure the uniformity and prevent the appearance of stoma. Prior to the last brush, non-woven cloth should be laid at the exhaust port and other positions for sealing and waterproof measures.

2. Waterproof construction measures for rigid roof

A rigid roof is a waterproof roof made of concrete. For this roof, in the process of waterproof construction, the quality of waterproof material must be guaranteed, which is the most important. Normally, when construction is often choose Φ Φ 4 ~ 6 mm, spacing is 200 mm two-way steel mesh is applied to the concrete of the waterproof layer. At the same time, it is also necessary to disconnect the position of the separation joint of steel mesh pieces to improve the rigidity of the waterproof layer.

In order to guarantee the effect of the rigid waterproof roof, at the end of the construction of the need for regular maintenance and operation, to avoid because of the lack of concrete affect the roofing seepage resistance, serious when will appear the roof leaks.

Despite the rigid waterproof roof its construction cost is low, operation process is relatively simple, but its for the roof at the grass-roots level of strain and temperature change adaptability is bad, affect the effect of the play, therefore, in the process of construction in the future, must carry on the technological innovation, from the two aspects to improve.

3.  Construction measures for waterproofing roof of roll materials

The different coils are fixed on the roof by the corresponding construction technology to achieve the waterproof effect, that is, the waterproof roof of the coils. This waterproof roof is also used for a long time in building construction.

To give full play to its good waterproof effect, the construction must be done in all the details of the handling work. For example, to make plate side seam, roof and impinges mouth connection position and the processing of roof corner location, where is the location of the drainage concentration, if mishandled, sealing is not strong, is easy to be a long time of the leakage phenomenon.
