Why do new houses leak?

First investigate the cause of the leakage at the most serious location and analyze the specific cause of the leakage. It may be that the waterproof layer has not been properly treated.

1. The exterior wall is leaking. Then you must find the property management company to solve the problem, because it is very troublesome to repair leaks in the exterior walls

2. Bathrooms, kitchens, and balconies are leaking, which means the waterproofing is not done well, so you need to remove the floor tiles or the bathroom caisson. Level it again to make it waterproof, and then lay the tiles. When laying the tiles, try to be careful not to scrape off the waterproof layer. Also, you need to pay attention to the position of the waterproof interface between the ground and the wall. Try to brush upwards, don't just brush the floor.

3. If the water pipe is leaking, you need to find out where the water pipe is broken. Find out the completed drawing of your original water and electricity laying, compare it to find out the direction of the water pipe, then check the leaking location, and remove the small area of ??floor tiles. Then repair the water pipes and test the water pressure. If there are no problems, you can re-pave the bricks. (Note that it is best to have extra floor tiles. If not, it is recommended to make them larger, otherwise it will be ugly to only repair one or two tiles.)

In short, according to the actual cause of water leakage, it is due to waterproofing problems. , or the problem of water pipe seepage, analyze the specific problems in detail, and then determine the repair plan. Do not do it blindly.
