Generally, if the roof leaks, we must first find the approximate waterproof and damaged position.
Common roof leakage and seepage are basically the roots of walls and pipes, and the other is to check from the highest point to the lowest point of the roof to see if there are cracks and whether the original waterproof layer or insulation layer is aging.
So how can we repair the roof leakage? There are the following steps:
Use special instruments to detect the leakage position of the roof.
Focus on inspection is the root of all parts. Such as that root of the wall, the root of the outlet pipe, etc. If cracks appear in these parts, the waterproof layer will be exposed. Then it will basically leak.
Eradicate the damaged part
The waterproof layer inside the damaged part needs to be exposed. Generally speaking, the roof adopts polymer modified asphalt waterproofing membrane. We will clean the damaged part of the coil.
Clean the shelter position of the roof.
Prepare tools such as broom, dustpan, scraper, etc., clean up the leaking parts and cement, concrete and other sundries in the last step, and keep the parts that need waterproofing clean and dry.
Waterproof the leaking parts.
Waterproof treatment will be carried out through the following procedures.
Wetting of base course: before painting, if the base course is dry, it needs to be wetted with water to ensure the adhesion strength of the coating film;
Large-scale construction: according to the scope of waterproof coating? Do the first coating construction, from the wall to the ground;
Brush thickness: don't brush too thick film for the first time, the film thickness is about 0.5mm;
Post-coating treatment: after coating, ensure the air circulation in the waterproof construction site, take rain-proof measures, and carefully check after operation, especially in wall joints, corners and places where water is easy to accumulate.
Roof waterproof test
After the water leakage construction is completed, it must be tested. After 24 hours, check the results of the closed water experiment, and the difference between the measured water level and the water level at discharge shall not exceed 5px. At the same time, go downstairs and carefully check whether there is leakage.
