What should I do if the surface leaks for four days? Generally, the owners who live on the top floor will encounter the situation of water leakage on the roof, it is inevitable that there will be a headache, and the water leakage on the sky is also a relatively common situation, and most of the owners have not returned some countermeasures for the water leakage on the roof, so today I will specially support a few tricks for you to solve the problem of water leakage on the roof, let's take a look. 1. The first thing to find the leakage of the roof is to find the leak, and the main way to find the leak is to find the leak from the high to the low part of the roof. The first thing is to see whether there are cracks on the roof, whether the original waterproof layer has aged, and whether there are bubbles in the original SBS waterproof membrane on the roof. And whether the gutter on the sky has been blocked.
2. When the owner begins to decorate the house, he must first do scientific construction, select qualified materials, avoid the hidden danger of water leakage at the joints and edges, and avoid destroying the original waterproof layer.
3. Pour concrete pier abutment on the roof, and pre-embed expansion bolts on the pier abutment. The position of the pier should be on the top of the structural wall, and it is strictly forbidden to pour directly on the floor slab (it is easy to overload, causing deformation and leakage of the floor slab). The size of the pier is determined according to the size of the local wind load, after the wind resistance calculation, and the drainage hole should be reserved on the pier to ensure the smooth drainage of the roof.
4. For some buildings covered with red tiles when the roof leaks, as long as the grass, moss or dust on the tiles are removed and the tiles are replaced, the leak-proof effect is the same. For flat roofs, if there are obvious cracks on the roof, you can use tools to open the cracks into a "V" or "U" shape, fill them with caulking ointment, and wrap them with waterproof membrane above and around the cracks after filling. If it is to strengthen the leak-proof effect, you can also lay another layer of waterproof membrane.
In order to be able to adapt to the deformation of the rigid waterproof roof, the top of the wall or beam is first leveled with cement mortar, and after two layers of linoleum are dry-laid, talcum powder is sandwiched in the middle, and then a prefabricated board is shelved. The end joints between the top of the roof panels and between the parapets should be filled with elastic material, and if it is a cast-in-place roof panel, a sliding support can be made at the supporting support.
