Rain rainbow waterproof case: how to deal with roof leakage

Choose a regular waterproof coating, and ask a regular construction team to come to the door for maintenance. The following steps should be followed:

1. The roof leaks first.

Find the leakage point from there, mainly from the top to the bottom of the roof (because water flows to the bottom). The first thing is to see whether there are cracks in the roof, whether the original waterproof layer is aging, and whether there are bubbles in the original SBS waterproof coiled material. If there are bubbles, it proves that water has entered the bottom of the waterproof layer, so it leaks. And whether the eaves gutter on the roof is blocked. In rural areas, there are still a large number of tile houses. When the roof leaks due to broken tiles, as long as

Precast slabs are mostly used in rural roofs, and the place where water leakage usually occurs is the contact between slabs. Therefore, the simple and economical repair method for the roof leakage of rural bungalows is to lay a layer of asphalt joint on the roof, but this method is not durable. A more durable method is to coat the roof with a left waterproof layer or latex.

2. Check whether there are multiple water leakage points or cracks.

If there is a large area of water leakage or multiple water leakage points on the roof, professionals should first check whether there are cracks. After the cracks are treated according to the previous scheme, the whole roof should be laid with waterproof coiled material. If you want to enhance the waterproof effect, you can lay insulation boards. Because the height of the insulation board is more than 20 cm, it can achieve the dual effects of protecting the waterproof layer and thermal insulation. Families who don't want to use insulation boards can consider using steel wire mesh concrete (the technical term is called steel wire mesh fine stone concrete), and the leakage prevention effect is also very good. There are cracks and water seepage on the wall, so professional construction teams generally use hanging baskets, and maintenance personnel will carry out external wall construction. The treatment method is: large cracks can be plugged, small cracks can be filled with glass glue, and external wall waterproofing agent can be used when repairing, which can be sprayed several times. Because the cracks in the external wall need to be repaired at high altitude, the public must ask a professional construction team to deal with them to prevent safety accidents from being released. In addition, the public should also pay attention to the fact that the roof must be dry before waterproof and leak-proof construction, because the water on the roof will not evaporate, and the new waterproof layer will be jacked up, and the waterproof effect will be invalid immediately. Therefore, it is not suitable for construction in rainy days, so we can only wait for the sun to dry the water before construction.

Make waterproof cosmetics

Secondly, if the roof is not waterproof, you only need to remove the leaking part 2~3cm deep and clean it. You can pour it with asphalt. Now there is a finished asphalt coating. If it is treated in sunny days, it will basically not leak. If there is a waterproof layer, it will be more troublesome. Need to remove the surrounding waterproof, waterproof again. When doing this, pay attention to the strengthening layer at the joint with the original waterproof. There are many ways to deal with leakage, so we should find some professional anti-leakage companies to deal with this problem. The roof leakage of a city building is inseparable from the quality of the building. Generally, the roof leakage of buildings is due to the weak foundation and floor problems, which are problems that developers need to solve. Therefore, the roof of the building in the city leaks, and we have to find a property management company to deal with it.

4. When the roofs of some red-tiled buildings in urban areas are leaking, as long as the grass, moss or dust are removed and then the tiles are replaced, the leakage prevention effect is the same. For a flat roof, if there are obvious cracks in the roof, tenon the cracks into a "V" or "U" shape with tools, fill them up with caulking ointment, and then wrap them with waterproof coiled material above and around the cracks. If you want to strengthen the leak-proof effect, you can also lay another layer of waterproof coiled material.
