How to deal with water seepage in the corners of the top floor

1. What are the reasons for water seepage on the wall?

1) The masonry mortar of the masonry is not full, the ash joints are hollow, and the capillary channel forms a siphon effect: the material texture of the interior decoration surface is loose, and it is easy to dissipate the moisture in the capillaries; The thickness of the plastering of the exterior wall veneer is uneven, resulting in the fast and slow water collection, the plastering is prone to cracks and shelling, and the bottom ash of the lattice strip is not dense and there are sand holes, resulting in water seepage on the wall.

2) The connection between the door and the window and the wall is not tightly sealed, the window roof is not set with olecranon and drip line, and the outdoor window sill board is higher than the indoor table. The outdoor window sill plate is not sloped downstream, resulting in water backflow.

3) There is no serious blockage and embedded sealing paste between the rear plug window frame and the wall, or the window frame protective tape is not torn off, resulting in water seepage.

4) Improper blockage of feet, hands, eyes and other holes.

2. How to deal with water seepage on the wall:

1) Find the existing seepage points and external wall cracks on the wall, chisel the external wall plastering layer, the parapet wall cracking plastering layer and the large-scale cracking cracks of the external wall at the interface between the masonry and the structural beam along the crack peak, and use the handheld cutting machine to cut the plastering layer before chiseling, so as to prevent the new hollow drum due to vibration when the plastering layer is chiseled.

2) After chiseling off the plastering layer, clean the base layer, and then spread a layer of steel wire mesh between the masonry and the structural beam to prevent the plastering layer from cracking again.

3) Repair the plastering layer, the plastering layer is repaired in two to three times, and a certain amount of micro-expansion agent is mixed into the repair mortar to reduce the interface cracks of the old and new plastering layers.

4) After the plastering layer is dry, then do the exterior wall paint, and finally wait for the wall paint to dry, and then paint one to two layers of waterproof coating film.

First: Determine where the water is leaking.

If it's a water pipe.

It's useless to make a surface.

If it is general water seepage.

The surface is okay.

Second: your wall is not close to the bathroom.

Kitchen. Or the balcony façade.

If yes, then the waterproofing is not done well.

Thirdly: there is generally a little bit of dampness.

with interface agent. The base film will do.

If severe. It's time to make a waterproof mortar.

Brush twice in a square about 2 kg.

Horizontally and vertically.

If the wall is soaked off.

Shovel off. Redo it.

Perhaps the biggest concern for homeowners living on the top floors is the lack of water seeping through the roof. Most people don't know what to do when they encounter this situation. So,What to do if the roof wall is smiling with a slow corner of water seepage

Why does the roof and corner of the building seep water?

What should I do if there is water seepage in the corner of the roof?- Find the seepage point. Under normal circumstances, the need to find a leak should follow the principle of "high to low". Check the cracked layer in the lower layer, aging impermeable layer, if the waterproofing effect is missed, and if the waterproofing membrane has entered the bubbles.

If there are air bubbles inside the waterproofing membrane, it means that water has penetrated into the waterproofing layer. At this point, the water leakage problem is serious. In addition, it is necessary to verify that the passage of the lower layer is not blocked.

What should I do if there is water seepage in the corner of the roof?- Cut the part that dripped from the ceiling and apply impermeable material to the dripping area. This is more problematic if the roof has been waterproofed beforehand. First, remove the previous waterproofing layer and re-waterproof.

Here, a reinforcing layer needs to be formed between the new and old waterproofing layers. In addition to insulating panels, homeowners can also use concrete.

What should I do if there is water seepage in the corner of the roof?4. If the homeowner is uncomfortable with this, you may need to place insulation on the roof. The insulation board can not only achieve the waterproof effect, but also play the role of thermal insulation.

5. In addition, the treatment method of roof leakage is uneven, and the treatment method is also different. Under normal circumstances, roof leaks should be handled by a professional trap person.

6. If the water seepage is serious and there is no possibility of repairing, just replace it with new tiles.

1. The main reason for leakage is that the roof structure is not reasonable enough, and the wall will leak or mildew after the rain. If you encounter problems during this period, you will need to redo the waterproofing. If no seepage is found, the pipe may have ruptured.

2. The service life of the house is too long, coupled with the lack of maintenance work, resulting in the aging of waterproof materials, and it is normal for the house to seep water.

1. Find the existing seepage point of the roof, locally chisel off the original waterproof layer and leveling layer, find the leakage location and chisel the hollow drum part of the leveling layer, and use a handheld cutting machine to cut the leveling layer before chiseling, so as to prevent the new hollow drum due to vibration when the leveling layer is chiseled. Chang Eyes.

2. After finding the leakage location, clean the balance and use polyurethane to coat the film thickly.

3. Do a irrigation experiment after repair, and the time is about 24 hours.

4. After the irrigation experiment is completed without leakage, the insulation layer and the waterproof protective layer are restored.

1. First of all, the entire roof insulation of the location of your house is lifted, including the insulation layer, so that the entire floor slab is exposed;

2. Then according to the position of the wall of your house and the neighbors on both sides of the adjacent house, build two walls close to the floor slab, and the height of the wall should be higher than (protruding Zhaochi) the entire roof;

3. First of all, make these two walls waterproof to block the leakage of water from the neighbor's house and then pass to your house;

4. Backfill the insulation materials of the floor, and wipe the roof of the building with cement;

5. Redo the waterproofing, including the location of the destroyed neighbor's house. This is a method of completely solving the leakage of the roof, but the amount of work is somewhat large. But if you do this, the leakage problem on the roof will be completely solved.

Even if there is a leak in the future, you can repair the damage and leakage on the roof of your own building, and you don't have to worry about the leakage of other people's houses coming to your house.

The solution to water seepage on the top floor depends on the cause of the water seepage. Here are some possible solutions::

1.Check the roof: If there is damage or cracks in the roof, it needs to be repaired or replaced. This prevents rainwater from seeping into the house.

2.Clean up the drainage: If the drain is clogged or poor, it can cause water to seep in from the roof. Cleaning up the drainage system can solve this problem.

3.Strengthen the waterproofing: Adding or updating the waterproofing layer on the roof can prevent water from seeping into the house.

4.Inspect the skylight and ceiling: if there is damage or cracks in the skylight or Paigo ceiling, it needs to be repaired or replaced.

5.Inspect exterior walls: If there are cracks or damage to exterior walls, it may cause water to seep into the house. Patching up the façade can solve this problem.

6.Install exhaust fans: If there is not enough ventilation on the roof, it can cause dampness and water seepage. Installing an exhaust fan can solve this problem.

The water seepage upstairs depends on the construction of the ground. If there is a large amount of water accumulation on the general blank ground, according to the grade and number of concrete, water seepage will occur in about half an hour; If it is a high-grade ground with waterproofing works, it will not easily seep water.

The basic process of doing backwater treatment downstairs. If there is open water in the leakage area, it must be treated first. If there is no open water, directly remove the wall decoration layer, spray the base treatment agent, use nano silicone waterproof adhesive with instant plugging agent to repair the large cracks in the base layer, hemp honeycomb, and paint the leakage part with high permeability epoxy back water surface waterproof coating, 24 hours after the back water surface waterproof coating initially plays a role, observe a few days if there is no sign of water seepage, you can restore the finishing layer.

As we all know, the use of houses will look old for a long time, and some families will also see water seepage and discoloration of the walls, which directly affects the aesthetics of the house. These kinds of problems must be resolved as soon as possible, otherwise the problem will get worse. So, what about water filtration on the wall?

Water seeps into the walls of the top floor of the houseWhat is the cause of the water leak? Let's take a look.

Water seeps into the walls of the top floor of the houseThe first thing to do is to repair the plaster on the wall. Under normal conditions, the plaster layer is divided into 2-3 repairs. And adding an appropriate amount of micro-expansion agent to the repaired mortar can reduce the cracks at the interface between the old and new plasters.

2. Wait for the coating to dry, then apply the coating to the exterior wall, and then apply one or two layers of waterproof coating, but after the exterior wall paint dries, a waterproof coating should be applied.

3. If there is a large area of cracks in the exterior wall, the gypsum layer must be cut by cutting the wall first before cutting the wall, which can effectively prevent the vibration caused by the gypsum layer during the cutting process. Hollowing phenomenon.

Water seeps into the walls of the top floor of the houseAfter removing the plaster layer, it is important to clean the base layer and then place a layer of steel mesh between the masonry and the structure to prevent the plaster layer from cracking again.

II,Water seeps into the walls of the top floor of the houseWhat is the reason?

1. With the previous explanation on how to filter the walls, I think my friend already has a background. There are many reasons for a filter wall. For example, when building a wall, the cement mortar is not full enough and the gray space is relatively large, which causes the capillary channel to form a siphon.

Secondly, the loose texture of the interior decorative surface material can also lead to water dispersion and leakage. If the thickness of the outer wall surface is uneven, the surface of the wall will peel off easily.

2. If there is a leak around the window, then it means that the open window frame and wall surface of the floor are not sealed into the imperfect cut of cleaning or protecting the window frame.

Water seepage from the roof and wall is one of the more common problems in the house. Water seepage on the roof can lead to structural damage to the house, and water seepage on the walls can affect the comfort of the room. Therefore, it is very important to deal with these issues in a timely manner.

1. Treatment of roof seepage.

1.Check for holes: The first thing you need to do is check the roof for holes. Visually inspect for damage, cracking, or loosening of tiles or roofing materials. If necessary, it will be repaired or replaced in time to ensure that the roof is complete and seamless.

2.Observe the eaves: The eaves are the junction between the roof and the walls, and they are also susceptible to rain. It should be noted that the drainage system of the eaves should ensure that the drainage pipe is unobstructed and not blocked, otherwise it will lead to an increase in water accumulation and aggravate the situation of water seepage.

3.Handling paint: Frequent transitions of waterproof paint printing are also a powerful sanity measure for water leakage.

Choosing a professional waterproofing paint, construction tool, and manner is crucial. The paint must be dry, otherwise water seeps into the wood and builds up moisture, which will only make rot worse, again making cracks more susceptible.

4.Installation of rainwater systems: In houses with steep roofs, rainwater harvesting systems can be installed to channel rainwater from the roof into the drainage system through stormwater pipes.

This not only effectively prevents water seepage from the roof, but also uses rainwater for environmental activities such as home planting.

Second, the treatment of wall water seepage.

1.Check the external wall gaps: Depending on the material of the wall, treat the external wall gaps in different ways.

For example, on cement walls, leak fillers can be used to fill small longitudinal cracks and effectively reduce water infiltration. For other wall slip and buried materials, a joint sealer can be used to fill the wall joints to prevent water from seeping into the room through the wall joints.

2.Fill the cracks in the wall: If there are large cracks found in the wall, they need to be repaired in time. Sealants can be applied to the cracks and then bricks or construction glue can be used to fill the cracks to ensure the integrity and stability of the wall.

3.Installation of rainwater harvesting systems: Similar to the solution to roof water seepage, the problem of wall water seepage can also be solved by installing a rainwater harvesting system. By installing drainage pipes, rainwater from the walls is channeled into the drainage system, reducing the impact on the interior space.

In short, it is very important to deal with the problem of water seepage in the house in a timely manner. With regular inspection and maintenance, the health and integrity of the home can be maintained, the longevity of the home can be increased, and the quality and comfort of the indoor air can be ensured.
