The roof is often exposed to the outside, and the wind and the sun are prone to water leakage, so the waterproofing of the roof is critical. There are many steps of roof waterproofing and leakage repair, so how to construct roof waterproofing and leak-proofing ? Let's understand together with the editor.
How to construct roof waterproof leakage repair
1. First make preparations
Before we fill the leaks on the roof, we must first make corresponding preparations. It is necessary to carefully check the drawings of the roof waterproofing project, determine all the structural manufacturing and construction according to the specific circumstances, to avoid leaving defects and lead to later rework.
2. Ensure the quality of waterproof materials
During construction, the quality of the waterproof material must also be checked to see if it has quality certification documents or quality inspection reports, etc., to ensure that it is a qualified product.
3. Pay attention to the roof drainage slope
In roof construction, the drainage slope of the roof should be considered, and the appropriate slope should be selected according to the material. Usually the drainage slope of the flat roof is 2% to 3%, and the longitudinal slope of the gutter and eaves should not be less than 1%, etc., according to the actual situation.
4. Construction in order
When we are waterproofing and leaking, we must carry out the construction in the correct order, such as building first, then installing equipment and pipes. After these are completed, the construction will be carried out in sequence.
5. Pay attention to the seam of the flat layer
Water leak repair must pay attention to the seam treatment, which is also a key part of the waterproof project. If it is not done well, there will be water leakage. Sealing materials should be embedded when waterproofing and leak repairing. Note that the flat layer should not be greater than six meters, and the asphalt mortar should not be greater than four meters.
What should be paid attention to
1. Before the construction of waterproof leakage repair, remember to remove the dust, sand and other debris on the base surface. If there are debris or unevenness on the surface, it will also affect the later construction.
2. When coating the waterproof layer, you must first check the dryness of the surface of the base layer. The surface should be suitable for drying. It should not be too wet or too dry. After standing for about 3-4 h, open it again to check the leveling layer and waterproof. The roll material can be constructed without a watermark.
3. If it is a large-area coating film construction, additional enhancement treatment should be done first to the water drop, gutter and other places. The thickness of the coating waterproof layer must also meet the requirements, and cracks, blisters and other phenomena must not occur.
