For slanted roof waterproofing, the structure itself is watertight due to its waterproof capability, and the waterproof treatment at the easy-to-leak detail node and the slope control of the sink water are the key to the construction technology.
First of all, we analyzed the reasons for the leakage of inclined roofs. We believe that there are two main reasons:
One is that concrete roofs are prone to cracks. The fine stone concrete waterproof layer has little flexibility and is extremely sensitive to uneven settlement of the foundation, minor deformation of the components, vibration and temperature difference of the house, etc., and can easily cause roof cracking and leakage.
The second is the four major factors affecting the waterproof layer design, construction, raw material quality and project management:
1) Inclined roofs should pay special attention to detailed node design. If the detailed waterproofing scheme is not properly designed, it can easily cause roof leakage;
2) If the waterproof construction of the roof does not strictly follow the operating procedures and design requirements, the waterproof measures at the local places are improper, resulting in poor quality of the leveling layer and detailed nodes, the thickness of the waterproof layer is not up to the standard requirements, and the construction of the isolation layer and the protective layer is not standardized. Leakage is inevitable;
3) Material properties of raw materials are also one of the important factors that affect the waterproof effect. The poor material quality and mix ratio of cement and aggregates, and the poor quality of waterproof materials all lead to roof leakage.
4) Management measures such as improper roofing procedures and product protection, maintenance and water storage inspections are not carried out in accordance with the relevant requirements, and the waterproof quality of roofing cannot be guaranteed.
Through practical summarization, the article concludes that for slanted roof waterproofing, the self-waterproofing ability of the structure itself is the basis of waterproofing, and the waterproof treatment at the easily leaking details node and the slope control of the sinking water are the key to the construction technology during the construction process. It should focus on these two tasks.
