The roof leaks, and the roof does not leak

You send a few** to see.

There are three major ways to do waterproofing in the old house:

1. First lay a flexible waterproof layer, where you can choose paint or membrane. Its construction conditions require that the moisture content of the base surface is not more than 9%, so it is suitable for construction in the summer after the hot weather and 5 consecutive sunny days. After completion, a water storage experiment should be carried out.

2. If the paint is waterproof, take "one cloth and two coatings" as an example: after cleaning the base layer, brush the paint again, dry the film, lay a layer of fiberglass cloth, and brush a layer of paint on the flattened surface to fix, and carry out the next coating construction after drying. The total thickness of the waterproof coating film should be more than 3 mm.

3. If you do the construction of waterproof membrane, after cleaning the base layer, brush the adhesive on the reverse side of the membrane and the base layer, paste and roll according to the elastic reference line from far and near, and finally do the seam closing inspection treatment.

Recommended choice of waterproof material:

1. Flexible mortar.

The ratio of emulsion to mortar is 5:4, which is elastic, and will not affect the waterproof effect even if the base layer is deformed and cracked. It is mostly used on the front surface of the wall and the bottom surface, and cannot be used on the back surface such as the top surface.

2. Hard mortar.

Also known as rigid mortar, the ratio of emulsion and mortar is 1:4, the coating does not need to be treated after the number is pressed, it can be directly tiled, it is more convenient, the cement surpluses after curing, and will not be leaked from the bag, and the waterproof effect of its back water surface is very good.

3. Polyurethanes.

Indoor and outdoor, the brush is very thick, about 3 mm, and the elasticity is more than 300%, any cracking of the substrate will not make it crack, and the waterproof effect is the best. Polyurethane is gelatinous and very thick, and it is very laborious to use a scraper during construction.

Don't know what material you make it from? The general material is easy to make no leakage, if the rainy season is relatively long, it can be made into a slope shape with a small chance of water leakage.

I am doing waterproofing, you buy some waterproof membrane is the kind of SPS roasted with fire, building materials have, this belongs to the most advanced and most economical now, the material is thin and thick, generally three millimeters thick is about 100 a roll, ten meters long and one meter wide, is ten square meters, how much money does your house buy more than one roll, involving the interface, the interface should be connected to ten centimeters, after the paving is baked with fire, and so the oil is hot and sticky to the roof, the premise that you have not done it must ask the master to do it, and the manual fee is seven yuan and a flat on our side, I don't know where you are, but you probably have one too.

If it is an old green tile house, you can only turn over the tiles, and replace the cracked tiles with new tiles. If it is a prefabricated board cover top, use the following methods:

Now the most safe and reliable waterproofing is to use membrane and asphalt, and first smooth the roof with cement and sand and ash! cement ratio 1; 3. The cement should not be too high. Wait for the cement to dry, then melt the asphalt at a high temperature, apply it evenly on the roof with a roller, and then lay the coil, and pour the melted asphalt on the edges and joints of the coil!

After drying, the surface layer can be smoothed with cement mixed with sand plaster. 100% guaranteed that you won't leak.

I'm doing waterproofing engineering! Even if you find a worker to do it, you have to supervise whether he finishes it as I say!

The buckle tile is the most suitable for my hometown house.

Spread plastic sheeting and cover it with felt.

Dear, thank you for your patience, yes 1, the installation of the pipeline is not fixed, resulting in looseness; There is an error in the position of the reserved mouth of the pipeline, the concrete is not poured in place, and the leakage prevention treatment is not done, which causes the pipeline to leak. 2. There are a lot of plants planted on the top floor of some houses, which actually has a certain impact on the waterproof materials of the house. Man-made construction damage is the result of water leakage of the waterproof layer; Caused by the damage of the pipeline installation and the damage during the construction of the protective layer or waterproof layer; The quality of the waterproofing material itself can also lead to the destruction of the waterproofing layer.

3. Many people will find that the wall is damp and black spots soon after moving in, or there is water leakage on the top surface and wall, and some homes are damp or even moldy and hairy in winter, all kinds of phenomena have brought a lot of inconvenience to family life. The construction personnel did not follow the construction requirements and specifications; When pouring the floor slab, the concrete was not fully leveled and tamped, and there were quality problems such as hollow drums, honeycombs, and hemp surfaces, I hope to help you! If you are satisfied with my service, thank you for giving me a thumbs up with your precious fortune hand.

Rooftop leaks need to be treated promptly to avoid further damage and safety hazards. Here are some ways to deal with it:

Find out where the water leak is. You can check the roof on a rainy day or if you use a water pipe to simulate rain to find out where the water leak is.

Clean the roof. Before repairing a water leak, the roof needs to be cleaned so that the location of the water leak can be better inspected and repaired.

Fix the location of the water leak. You can repair the leak with waterproof materials such as waterproof paint, waterproof tape, or waterproof membrane. If the leak is large or more serious than the wheel, the entire roof may need to be replaced.

Strengthen waterproofing measures. To avoid future leaks, you can enhance waterproofing measures such as putting a waterproofing layer on the roof or installing a drainage system.

Please note that if you are new to roof repairs or are unsure of how to deal with water leaks, please consult a professional roof repair professional.

The treatment method of roof leakage on the top floor is as follows:1Find out where the water leak is.

First of all, you can find out the location of the water leakage, you can observe the condition of the roof, or watch the lead hall to check the water seeping out of the ** when it rains. 2.Clean up the leaks:

Clean up the debris and dirt from the leak to better check the cause of the leak. 3.Check the roof:

Inspect the roof for breakage, cracks or other damage, and repair it in time if any. 4.Replacement of broken materials:

If you find that the tiles, slabs or other materials on the roof have been damaged, you need to replace them in time. 5.Strengthen waterproofing measures.

Waterproofing measures can be added to the roof, such as applying waterproofing paint or installing a waterproofing layer. 6.Regular check-ups:

Regularly inspect the condition of the roof to detect and deal with water leaks in time to avoid water leaks causing more damage to the house.

If you have a leaking roof, we recommend that you take the following steps to deal with it:

1.First of all, please collect the water as soon as possible to avoid further damage.

2.Look at the location of the water leak. If the leak is located above the roof, there may be a pipe leak. If the leak is located under the roof, there may be a roof leak.

3.If the leak is located above the roof, there may be a pipe leak. At this point, you should turn off the faucet and then check the water pipes for cracks, damage, or looseness. If you find a problem, it is recommended that you contact a professional for repair.

4.If the leak is under the roof, it may be a roof leak. At this point, you should first check the roof for cracks, damage, or looseness. If you find a problem, it is recommended that you contact a professional for repair.

5.If you can't determine the cause of the water leak, or if you can't fix it yourself, it is recommended that you contact a professional for diagnosis and repair.

1. Waterproof coating: After the waterproof coating is painted, the layer film on the cement roof achieves the purpose of waterproofing, but if it is not well combined with the cement base, it is easy to bulge and crack;

2. Asphalt coating: the waterproof effect of asphalt coating is also good, ** relatively cheap, but it is not frost resistant and easy to fall off;

3. Polymer membrane: This material plus the protective layer of concrete mortar can maintain the waterproof effect for a long time.

4. Roof leakage treatment method:

1) First of all, check the roof to find out the cause of water leakage, whether it is caused by pipes, waterproof layers, or joint cracks, and only after finding the cause of water leakage can appropriate methods be taken to repair it.

2) If the roof has not been waterproofed before, then it is best to do an overall waterproofing, and you can choose a better quality polyester waterproof coating or polyester waterproof membrane. If you have done waterproofing before, and it has been for a long time, then the waterproof layer may basically lose its effect, so you can only do it again.

3) In the waterproofing treatment, first clean the base surface, screed layer to the concrete structure layer, use a hair dryer, broom to clean up the debris, let the base surface fully moistened, and then fill the cracks, close the cracks, and level with mortar.

4) Next, use polyester waterproof brushing, the coating should be as uniform as possible, not local deposition, the time interval between the layers should be grasped, and the coating film can be constructed without sticking to the hands. The base surface is required to be smooth, firm, no leakage, unevenness and no cracks, and pay attention not to hollow drumming.

5) At the same time, additional reinforcement treatment should be done on the water drop, yin and yang corners, gutters and other parts, and the direction of each brush is perpendicular to the previous one. When the waterproof layer is painted on the corner and façade, it should be painted several times, and there shall be no flow and accumulation, and the inside of the roof wall and the top must be waterproofed according to the design and specification requirements.
