Who will repair the water leakage on the roof of Li Nan 12 Lianhuachi, Fengtai District?
If the roof leaks locally, it can be repaired locally, and the maintenance scheme is slotting. The validity period of the local maintenance area is about 20 years, and there is no guarantee that other areas will leak water. Of course, some roofs can also be grouted to deal with slight leakage. Grouting is cheap, simple in construction and short in validity, depending on personal choice.
If it is a large area of leakage, it is recommended to do overall waterproofing. Each company's construction scheme and technology are also different. But there are three general schemes:
1, ensure that there is no floating ash on the surface, spread waterproof coiled material, and make water stop on the non-public roof. The price is lower, the validity period is about 3-5 years, and the warranty period is 1 year.
2. The surface is waterproof for three times, and the non-public roof is made of water stop. The price is moderate, and a protective layer can be added. The validity period is about 15, with a five-year warranty.
3, artificial broken floor layer, repair the grass-roots, restore the roof additional layer and waterproof, the price is higher, the validity period is about 30 years, and the warranty period is 5 years.
This is the standard solution. In fact, every company will customize the solution according to the on-site situation. Besides, don't listen to 10 warranty and 20-year warranty. These are slogans and useless. The state stipulates that the warranty period of housing construction projects is 5 years.
Guerrillas will be cheaper, but the quality and after-sales cannot be guaranteed. Of course, there will be some good teachers in the guerrillas, but it is still recommended to find a company to do it. The choice of company depends on the establishment period, construction case, owner, maintenance plan and service contract. At present, many companies will provide free on-site survey services and issue scheme quotation contracts. You can ask someone to visit them first, then observe their proposal quotation contract, and then decide whether to cooperate with them.
