1, construction environment
In order to effectively ensure the smooth progress of construction and the quality of coiled material paving, the roof should be waterproof in sunny days, and the construction temperature should be kept at +50℃~+350℃, because the related polymer modified asphalt and polymer waterproof coiled material cannot be constructed below negative temperature, and the coiled material can be paved by hot melting method above-100℃, which is very suitable for use under negative temperature conditions. Avoid working in the open air in high atmospheric humidity and windy weather, otherwise corresponding technical treatment measures should be taken.
Step 2 Prepare for work
Before roofing waterproof construction, the construction unit shall organize relevant technical personnel to review the roofing engineering drawings, master the detailed structure and related technical requirements in the construction drawings, and prepare the roofing engineering construction scheme or technical measures according to the actual situation of the project. This can avoid the defects left after construction and cause rework. At the same time, the project will be carried out in a planned way according to the construction organization, so as to prevent the omission, confusion and inversion in the work process from affecting the quality of the project, thus bringing unnecessary losses.
3, material quality
The quality of waterproof materials directly affects the quality of waterproof engineering, so it is particularly important to choose suitable and qualified waterproof materials when roofing waterproof. The quality of waterproof materials must conform to the provisions of relevant standards and be inspected by quality inspection departments. The appearance of coiled material waterproof layer should be straight, and there should be no distortion and fold.
4. Protective layer setting
The setting of protective layer should comply with the provisions of this process, and an isolation layer should be set between rigid protective layer and waterproof layer. The setting of frame joints on the surface of protective layer shall meet the national standards and design requirements. Block protective layer should be laid flat, uniform and dense, and the design of frame joints should be correct.
In the process of roof waterproofing, construction workers should pay considerable attention to waterproof measures in one step, regardless of related preparations or operation process, and should not be careless. Because the waterproof work of the roof is often closely related to the whole house, improper operation will generally affect the service life of the house and has a great relationship with family life. As for the concrete operation process of roof waterproofing, Bian Xiao has a detailed introduction on it. You might as well learn it, which will also help to increase our decoration knowledge.
