How to deal with balcony water seepage

Treatment of water seepage from the balcony:

1. Balcony leakage should be found first, mainly from the high of the roof to the low place, because the water flows to the bottom. Look at whether there are cracks in the roof, whether the original waterproof layer has aged off, and whether there are bubbles in the original waterproof membrane of the roof.

There is also whether the gutter on the roof is blocked, in the countryside, there are still a large number of tiled houses, when there is a roof leakage due to tile breakage, just replace the tile, this step is also called "leakage".

2. If the roof is only the original without waterproofing, you only need to clean the leaking part after removing it 2 3cm deep, and then you will use asphalt to water it. If there is a waterproof layer, it is more troublesome, to remove the waterproof within the surrounding area, re-do the waterproofing, and pay attention to the original waterproof junction to do a reinforcing layer.

1. Aluminum alloy window problem: The waterproof sealing level of aluminum alloy window is not enough, and cracks may appear after aging and hardening for a long time. There is no drainage channel in the aluminum alloy window structure cavity, and the rainwater entering the aluminum alloy structure cavity under the action of indoor and outdoor wind difference is not discharged in time by the drainage system, resulting in water pressure leakage along the wall.

2. The problem of the window and the construction team: the joint between the aluminum alloy window and the wall is the part that is easy to leak, and the material is not filled according to the requirements, which will also cause rainwater leakage in the later stage.

1. Check the joints between the window and the wall, remove the original aging or damaged sealing materials, and then treat the base layer clean, smooth and straight. For the large gap between the window and the wall, fill it with styrofoam, and the inner and outer sides, the window frame and the window sash must be filled with glue and sealed.

2. For balconies with serious leakage, waterproofing should be redone, especially the waterproofing of the top surface and wall. It is also possible to add a water baffle above the wall to reduce the impact of rainwater on the infill layer between the window and the wall. When repairing, good sealing materials should be selected, and all leakage points should be carefully sealed.

Leakage caused by poor wall waterproofing: If the bathroom leaks and the wall of the room adjacent to the bathroom is wet, there is no leakage downstairs. In this case, the waterproofing of the bathroom wall is not done well.

Solution: Remove a row of floor tiles and a row of wall tiles near the nearest position of the wall root at the leakage, re-waterproof in this area, and construct in strict accordance with the operating procedures. In particular, be careful not to damage the previous waterproofing layer.

It's best to be able to test the waters. There is no problem in testing the water, and then re-install the bathroom wall tiles and floor tiles.

Leakage caused by not doing a good job of waterproofing the bottom of the bathroom: this situation is more troublesome. Because many bathrooms are sunken toilets.

It is necessary to dig out all the backfills of the sinking pit in the leaking place, and there is a certain working surface to facilitate construction. After the waterproofing of the bottom of the pit is done, there is no problem in testing the water, and you can backfill it again. And use cement mortar to level and remove this range of floor tiles, and then waterproof this part to ensure that there is no problem, and then lay the bricks.

It is the leakage caused by the water supply and drainage pipes: find the source and replace the water supply and drainage pipes. Pressure tests are carried out on the water supply pipes.

After the installation of the drain pipe is completed, you can pour water into it to observe and make sure that there is no problem. Of course, other waterproof layer damage caused by the repair of water pipes must also be repaired.

It is recommended that you can find Chengdu Anhongteng Cleaning Co., Ltd., our company has been managed and cooperated by Sichuan Waterproof and Thermal Insulation Engineering Company "Sichuan Regional Project Department". For a long time, the company has taken advantage of the business philosophy of "survival by quality, development by reputation", and now has more than 160 regular employees through hard work, and is a professional service company that provides comprehensive cleaning, renovation, anti-corrosion, waterproof leakage, marble polishing crystallization, and cleaning trusteeship for buildings, hotels, shopping malls, hospitals, residential quarters, schools, enterprises, municipal and other places and buildings (structures). The company operates in accordance with the standards of ISO9001 and 14001 environmental quality system.

Project performance: In November 2013, our company was awarded by Sandaoyan Town, Pixian County and the developer to designate the maintenance unit for the community with water seepage on the outer wall of Sandaoyan Town; The tentative cost of the contract is 260,000 yuan.

Project performance: In August 2014, it was awarded the winning bid to designate the exterior wall waterproof maintenance unit of Dayuan Community in High-tech New Zone; The total cost is 300,000 yuan.

and other performance.

Inspect the joints between the windows and the walls, remove the original aged or broken sealing materials, and then clean and straighten the base layer. For the large gap between the window and the wall, fill it with styrofoam, and the inner and outer sides, the window frame and the window sash must be filled with glue and sealed.

To solve the stubborn problem of water seepage on the balcony, it is to use a silicone structural sealant that does not shrink and has good adhesion.

First of all, ensure that there are no floating and sinking and other debris on the balcony window and the surrounding wall to be glued, seal the gaps with structural adhesive, and use the inclined plane of the glue nozzle to make the arc-shaped surface of the glue to achieve the effect of no water storage and sealing.

It's okay to do waterproofing, no need to do it again. It may be that the waterproofing outside your balcony is not good, but you can also do it when you do it.

Now the balconies are not waterproofed.

Just take care of the windows.

Either do it from scratch or grout it with asphalt.

The first priority is to find the problem. The owner's new house is decorated not long before there is water leakage, water seepage, and then every rainy day, the balcony will appear this situation, deal with many times, the problem may still be the same, at this time to smash the balcony open, find out the cause of the leakage, and then deal with it.

Water seepage from the balcony may be the cause of the balcony itself. Basically, when it rains outside, there will be water accumulation on the balcony, and the water seepage place is generally from the corner of the closed balcony, and the seepage is basically caused by the balcony closure is not in place, which must be noted. After this problem occurs, you can find someone to smash the outer edge of the balcony open to find out the ultimate cause.

At this time, the balcony is basically not waterproof, and when the balcony is installed, the decoration destroys the solid wall at the bottom of the balcony, and then this situation occurs, the way to deal with it is to smash the outer edge of the tiles and redo the waterproofing, which can solve this problem.

1. Do waterproof treatment for the balcony, so as not to cause inconvenience to the life of the lower residents due to water leakage, pay attention to the thickness of the waterproof layer at least 5 mm during construction, and generally paint the waterproof coating 2 to 3 times. And at the joints between the floor and the wall of the balcony and these places up to 30 cm, it is also necessary to paint waterproofing paint. In addition, it should be noted that in the decoration and arrangement of the family balcony, it is not only necessary to do a good job of waterproof material painting, but also remember to make a waterproof slope to facilitate the flow of water to the drainage outlet.

2. To level and slope the balcony leakage, first of all, the balcony ground and façade should be leveled with cement mortar, and there must be serious waterproof problems.

3. If there is leakage on the balcony board surface or kick part board surface due to structural cracks, high-pressure grouting treatment shall be adopted. First, find out the leakage site, nail the leakage crack, and inject waterproof foamed polyurethane at high pressure. After the polyurethane has solidified, the nail is removed.

If the crack is too large, the 200 concrete around the crack is chiseled off, and the fine stone concrete grout is used, and a 2mm thick polyurethane waterproof layer is constructed on the concrete surface.

Processing Steps:

First, clean up all the original fills;

second, seal with a small amount of expansion glue;

Third, the surface is closed again with plugging spirit;

Fourth, all closures are closed again with sealant, taking care to do both inside and outside.

How to prevent water seepage on the balcony:

1. Seal the balcony.

Materials are very important, now more than 90% of new owners will choose closed balconies, the choice of materials is critical. With good aluminum alloy materials and good installation and decoration, there will generally be no water leakage problems. Owners should choose brand aluminum alloy materials, quality assurance and better after-sales service.

The thickness of relatively strong aluminum alloy building materials is about right. Many building materials on the market that claim to be 1mm may only have the actual thickness, and the owner can measure or carefully distinguish. In addition, good aluminum alloy windows are relatively seamless, and are not prone to quality problems such as water leakage and window detachment.

Second, do decoration.

It is necessary to choose a regular company, Zhou Guobiao believes that good decoration is also very important, and the owner should try to choose a regular home improvement company if conditions permit. Taking waterproofing as an example, Chenchuang Decoration's practice is generally waterproof after the waterproof layer is done on the balcony floor. Fill the balcony floor with water and keep it submerged for 24 hours, even up to 1 week.

After confirming that there is no water seepage, we will start laying tiles, etc.

Regular renovation companies will also give a warranty, and the warranty period for water seepage and leakage in balconies and bathrooms is generally 5 years. If you have found a regular decoration company before, all these costs will be borne by the decoration company.

If you are looking for a private renovation, the owner can also do a water leakage test by himself. Soak in water for at least 24 hours, waterproof well, and then apply tiles, etc., so as not to need to renovate.

If you want the window not to leak, the sealing glue of the aluminum alloy window is very important, and the structural adhesive should be used, not ordinary glass glue. Zhou Guobiao said, especially outside the window, often exposed to rainwater, ordinary glass glue is easy to melt, and good sealant is more elastic to the touch, with a life span of more than 5 years.

1. If the upstairs balcony leaks, it will be treated at the top of the downstairs balcony;

This treatment method has, such as waterproof grouting pressure glue, but the effect is not too good, the symptoms are not cured, and it will reappear after a long time;

Second, if the upstairs balcony leaks, it will be dealt with at the balcony of the upstairs household;

It is necessary to find the specific cause and prescribe the right medicine

If there is a problem with the water pipe, then repair and deal with the water pipe;

If the sewer pipe is ruptured or the access port is not tightly covered, then dispose of the sewer pipe;

If it is a backwater from the sewer pipe and it is not waterproofed, then either deal with waterproofing or deal with the backwater problem or both;
