What is the best way to solve the water leakage in the house?

1, when water leaks along the bottom of the frame beam, it is necessary to remove the decorative layer at the crack of the external wall, scrape off the mortar in the crack on the top surface of the brick wall, rinse it off, wedge it with iron sheets, then fill it with 1: 2.5 cement mortar, recess it into the wall 10mm, fill it with flexible waterproof sealant, and then fill the decorative surface of the external wall.

2. If there is water leakage on the external wall of the building, it can be directly removed by internal painting to find out the leaking brick joints. The parts where the brick joints are not dense are filled with mortar, then washed clean and filled with 1: 2.5 cement mortar.

3. When there is water seepage in a large area, but there is no obvious crack on the exterior decorative surface, the exterior decorative surface should be scrubbed clean. After drying, the component A and component B of the cationic chloroprene polymer emulsion are mixed and stirred evenly according to the ratio of 1: 1, and then 42.5 ordinary portland cement is added according to the water-cement ratio of 0.4, and the cement slurry is stirred evenly. Treating brick joints by pointing with polymer cement slurry.

What should I do if the house leaks? 1. The leaking exterior wall of the house is leaking. Then we must find a property to solve it, because it is very troublesome to repair the leakage of the external wall.

2. The leaking bathroom, kitchen and balcony of the house are leaking, that is, the waterproofing is not done well. Then the floor tiles or caissons in the bathroom should be removed, leveled and waterproof again, and then bricked. Try to be careful not to scrape off the waterproof layer when sticking bricks. There is also the need to pay attention to the waterproof interface position between the ground and the wall, and try to brush it up instead of just brushing the ground.

3. If the leaking water pipe of the house leaks, it is necessary to find out where the water pipe is broken, find out the completion drawing of the original water and electricity laying, find out the direction of the water pipe by comparison, then find out the leaking position, dismantle the floor tiles in a small area, and then repair the water pipe again. Hydrostatic test, if there is no problem, you can stick bricks again. (Note that the more extra floor tiles, the better. If there is no suggestion, just look at it and make it bigger, otherwise it will be ugly if you only fix one or two. )

In short, according to the actual cause of water leakage, whether it is waterproof or water pipe seepage, the specific problem is analyzed in detail, and then the repair plan is determined. Don't do it blindly.

4. In case of water leakage in the leaking bathroom of the house, it is necessary to clean up the grassroots before making the waterproof layer. One of three methods can be used to waterproof the board surface (cement mortar leveling layer mixed with waterproof agent, modified asphalt waterproof coiled material and polyurethane waterproof coating). After the waterproof layer is completed, the surface construction shall be carried out after the irrigation test and inspection are qualified.

5. Cement mortar leveling layer mixed with waterproof agent can be used as a simple tool for direct bricklayer; Modified asphalt waterproofing membrane can be divided into wet paving and hot paving. Wet paving is easy to operate and can be arranged by masons, while hot paving requires gas tank spray guns to arrange professional waterproof workers. The construction methods of polyurethane waterproof coating are roller coating and brush coating, and the scope is small. The surface construction belongs to the type of bricklayer, and the main materials are cement, yellow sand and surface materials.
