Is there a requirement for waterproofing in the kitchens of new high rise buildings?

Need. 1. The waterproof treatment of the kitchen is also important, because the kitchen is equipped with base cabinets and hanging cabinets, not only to pay attention to the waterproofing in the kitchen, but also to prevent water from leaking outward.

2. Clean up the construction site and sprinkle water to make it fully moist but there must be no water.

3. The variety, brand and mix ratio of waterproof materials must meet the provisions of relevant standards of environmental protection standards. The product has a certificate of conformity.

4. The basic layer of the waterproof layer shall not be uneven, loose, hollow, sanding and cracking. The moisture content is less than 10%. The ground waterproof layer of the kitchen and toilet with floor drain is upturned from the contact with the wall body around it, not less than 25 cm above the ground, no flooding, no water accumulation, and no leakage in the 24-hour closed water test.

5. The waterproof layer is firmly pasted, without slippage, skid, blistering and wrinkles. Floor drains, squatting pits, drainage outlets, etc. should be kept unblocked, and protective measures should be taken during construction.

If you don't make any changes to the kitchen floor during the renovation (of course you will have to provide proof). Then it should be up to the developer to compensate the users downstairs for their losses. According to the "Residential Design Code", kitchens, balconies, bathrooms and roofs should be treated with water.

The downstairs owner can ask the upstairs owner to compensate according to their actual loss, and ask the other party to do waterproof treatment, as for the developer, see if you have waterproof requirements in the purchase contract, if not, then it can only be upstairs and downstairs communication.

The kitchen needs to be waterproofed, and it is also necessary to do a closed water test. As far as kitchen waterproofing is concerned, the efficiency of use is very low but very important. Another source of water in the kitchen is the upper and lower water outlets, and there are several situations that can cause overflow accidents

1. The drain is blocked, resulting in backwater;

2. The inlet pipe is ruptured, resulting in a large amount of water leakage;

3. The water basin is not tightly closed, and the water splashed on the countertop flows continuously through the joints;

After the waterproofing project is completed, seal the door and the drain, fill the bathroom floor with water to reach a certain liquid level height, and make a mark, if the liquid level does not drop significantly within 24 hours, especially the roof of the downstairs house does not leak, the waterproof is qualified. If the acceptance is unqualified, the waterproof project must be redone as a whole and then re-inspected.

For the acceptance of lightweight wall waterproof construction, the water test should be taken, even if the water pipe is sprayed continuously from top to bottom on the wall of the waterproof coating for 3 minutes, and the other side of the wall will be observed after 4 hours, if there is no permeability, it can be considered that the wall waterproof construction acceptance is qualified.
