What should I do if the exterior wall of the commercial house is seriously leaking

Leaks in external walls are more difficult to deal with. The first thing that needs to be done is to find the cause of the water leak. Sometimes a wall is just a crack at work.

The choice of material is secondary. If it is a crack, it is recommended to plug it directly with glass glue. Dry waterproof materials should not be used.

There is a transparent liquid waterproof material imported from South Korea (forgot the name), which is brushed directly on the cement to change the watertightness of the cement.

After finding the cause of the external wall leakage, you can take certain measures against it, for this type of external wall water leakage, the main thing is to repair the mortar layer, the surface cracks, the hollow drum layer and the water leakage micropores, so as to restore the waterproof protection function of the cement mortar layer.

In the leakage of the external wall, if the gap on the surface of the wall is wide, the gap should be wetted by sprinkling water, and the inorganic waterproof plugging material should be used to fill the gap, if the gap is narrow, the polyurethane waterproof coating can be used to paint the gap, and the thickness should be controlled between millimeters during the painting process.

For the leakage of the exterior wall of the house, many people feel that they do not know how to start, the leakage of the exterior wall of the house is because of the particularity and high-altitude crime and other factors that make people very headache, especially because of the improper construction of the decorative bricks on the exterior wall of the building, the wall leakage is easy to cause the boundary mortar of the decorative bricks is not full to form a void. ButWhat to do if the exterior wall of the building is leaking

1.The first thing to do when discovering the leakage of the exterior wall of the house is to find the cause of the leakage, which can be analyzed from the materials selected in the construction of the house, so many modern residences are made of ordinary concrete perforated brick materials, and after the investigation and use of recent years, it is found that the exterior walls with ordinary concrete perforated brick materials almost all have external wall cracking and water leakage.

2.The reason for the leakage of the exterior wall window sill is more complicated, it may be the roof or the exterior wall somewhere water seeps in, and then seeps down along the wall mortar layer, and then seeps in from the window sill, so to solve the problem is to deal with it from the outside, but unless the outside is redone, it is not easy to find the leakage point, the developer will not give you this, basically no operation, unless the whole building is leaking up and down!

Water leakage treatment method for exterior wall of house

1.After finding the cause of the external wall leakage, you can take certain measures against it, for this type of external wall leakage, the main thing is to repair the mortar layer of the external wall, the surface cracks, the hollow drum layer and the leakage micropores, in this way to restore.

The waterproof protection function of the composite cement mortar layer.

2.In the leakage of the exterior wall, if the gap on the surface of the wall is wide, the gap should be wetted by sprinkling water first, and then the inorganic waterproof plugging material should be used to fill the gap. The specific method is to chisel the hollow drum part of the cement mortar layer, and then use the polymer cement mortar to repair and level, wherein the polymer, cement mortar should be modeled like a hidden layer plastering, and the thickness is to repair and smooth the wall as the standard.

3.If the gap is narrow, polyurethane waterproof coating can be used to paint the gap, and its thickness should be controlled between millimeters during the painting process, and for the width of the gap, it is based on whether the inorganic waterproof plugging material can be filled.

For the cause of the leakage of the external wall of the building, we understand the correct way to deal with it after we understand it. The above is what to do if the external wall of the building is leaking and how to deal with the leakage introduced to you today, and this is the end of it.

Water seepage on the exterior wall of the house will not only affect the quality of the whole house, but also cause mold on the walls and furniture, etc., which will affect people's mood. So how to deal with water leakage on the exterior wall of the house? Whose responsibility does it belong to?

1. Who is responsible for the leakage of the exterior wall of the house.

If it is within the warranty period, it is the responsibility of the developer. Generally, the warranty period for waterproof projects such as exterior walls and roofs is 5 years, and the developer will repair them free of charge if there is a problem; When the warranty period expires, if there is water leakage on the exterior wall of the house, you can apply to the property for housing maintenance** withdrawal and maintenance, and the property has relevant obligations such as formulation, approval, and inspection.

Second, what to do if the exterior wall of the house leaks.

1. First find the location of the external wall leakage, and mainly repair the mortar layer, cracks, hollow drum layer and leakage holes of the external wall. Use a shovel to chisel the position of the hollow drum of the cement mortar layer, and then use polymer and cement mortar to repair and flatten, when repairing, polymer and cement mortar should pay attention to layering during construction, and wipe it evenly, and the thickness can be leveled with the wall repair as standard.

2. Check the leaking gaps of the exterior wall, if the gaps are wide, it is recommended to sprinkle water on the gaps to wet them first, and then use inorganic waterproof plugging products to fill the gaps; If the gap is narrow, it is recommended to choose polyurethane waterproof coating to fill the gap. Note that the thickness of the waterproof of the exterior wall of the house should be within, and the gap of the inorganic waterproof plugging material can be directly filled, which belongs to a wider gap, and the description of the plugging material can not be filled is a narrow gap.

Conclusion of the article: Who is responsible for the leakage of the exterior wall of the house and how to deal with it is introduced here, I hope it will be helpful to you. In general, the developer is responsible for the maintenance period and water leakage problems, and the property has the obligation to coordinate and notify.

Water leakage treatment method for building exterior wall: fill with caulk, spray waterproofing agent, and apply waterproof paint.

The caulk has strong adhesion, small shrinkage, strong color firmness, anti-crack flexibility, good decorative texture, pressure resistance, wear resistance, and mildew resistance. However, after using it for a period of time, it is easy to become dirty and black, the paste strength is low, and the powder is easy to fall off.

The waterproofing agent varies with the construction season, and the composite retarder and other components have the function of reducing the heat of concrete hydration and reducing the temperature difference cracks. Moreover, the waterproofing agent can deeply penetrate into the concrete, which has the functions of waterproofing, anti-corrosion, dust-proof, anti-wear, protecting concrete and the internal steel bars of concrete, and prolonging the service life of concrete.

The waterproof film formed by the waterproof paint after curing has a certain extensibility, elastoplasticity, crack resistance, impermeability and weather resistance, which can play a waterproof, impermeable and protective role. The criterion of passing is that we can clearly see that there is a uniform layer of crystals on the wall.

Causes of water leakage on the exterior wall of the building:

With the arrival of the rainy season, the problem of water leakage on the wall is gradually increasing, if there is a water leakage problem on our wall, we must find out the specific cause of the water leakage, in order to solve the problem of water leakage from the root.

Problems with the insulation layer of the wall cause rainwater to leak into the insulation layer, and then seep into the wall, and on the wall that seeps into the interior from the exterior wall, resulting in putty falling off, mold, peeling and other phenomena on the surface of the interior wall.

Cracks appear on the wall surface of the exterior wall, and the cracks on the wall may be cracked in many places or the cracks are relatively large, which leads to the rainy season, the rainwater will slowly seep into the wall through the cracks, and with the increase of rainfall, it will return to the wall, causing problems such as wall leakage.
