What should I do if the roof panel leaks? What to do if the board room is leaking

When there is leakage water in the roof panel, we often treat it from the top of the roof, but the indoor leakage point treatment effect is not very ideal, and the problem cannot be solved from the source. Because the waterproof layer of the roofing membrane is very easy to hollow, the membrane naturally forms a mutually connected channel, and the leaking water will flow everywhere no matter which damaged leakage port enters the membrane, resulting in multiple leakage points, blocking this place, and the waterproof layer will not leak from other places.

If it is a roof, such as the roof is a face brick, it is necessary to check all the surface brick joints, whether the surface bricks have hollow drums, check all the roof flashing ends, out of the details of the roof pipes, and deal with all suspicious positions, the hollow drum surface bricks can be repasted, the flashing end and the roof pipe can be resealed with sealing materials, and the cracks of the parapet can be painted with waterproof latex, and if there are still problems after treatment, you can spray nano-level waterproofing agent treatment on the whole roof, including the suspicious part of the parapet wall. If the leakage is treated locally, the leakage position can be cleaned first, and then applied without leakage, and then waterproof latex can be applied. There are many reasons for water seepage in the roof panel, and it is also the most difficult to deal with after leakage.

There are many reasons for the leakage of the roof slab: first of all, the floor slab, the floor slab is not compacted due to vibration during construction, and the steel bars or steel pipes, iron nails or other iron parts rust through the floor slab to form gaps. At the same time, due to the failure or partial failure of the waterproof layer, more water enters the perlite insulation layer through the waterproof layer, and then enters the cracks of the floor slab, and enters the residents' homes through the floor slab.

The treatment method is to dig up above the roof structure layer above the leakage point (the excavation area depends on the specific situation), and then paint the polyurethane material on the structural layer, do a good job of thermal insulation leveling layer, and closely overlap the damaged waterproof layer with the surrounding waterproof layer, and then make up the insulation board, fine sand protective layer, bricks, etc. in turn.

Roof slab leakage, first of all, we have to analyze the cause of water leakage, only to find the cause in order to prescribe the right medicine, the roof panel leakage water may be caused by, the quality of reinforced concrete slab is not up to standard, there is a phenomenon of microporous infiltration; The conservation measures taken are unreasonable or the maintenance time is too short; The waterproof coating does not extend well, causing it to be pulled apart with the cracking of the board surface; The construction is not carried out in accordance with the process requirements of secondary vibration and secondary plastering; Cracking of the roof panels. The measures that can be taken for these phenomena are to partially clean the surface of the damaged waterproof layer to ensure that the surface is free of debris and dust. Brush the same waterproof coating on the surface of the waterproof layer again, or completely remove the surface of the damaged waterproof layer, expose the roof structure, close the cracks through the plugging measures of water seepage on the board and wall, and apply waterproof coating and paste fiber paper cloth reinforcement within a certain area.

Solution to water leakage in the board room:

Water leakage on the floor of the mobile house may be caused by water seepage caused by gaps between the wall and the floor. We need to fill and repair the gaps, for example, we will first clean up the debris at the gaps, and then apply a layer of waterproof paint, paste the non-woven fabric and then apply the waterproof coating, so that the gap will be filled all the time. Or we can use glass glue, styrofoam and other materials to fill the gaps.

1. We should deal with the foundation when building the prefabricated house. Generally, the floor of the prefabricated house should be at least 5 cm higher than the outside. If the floor of the prefabricated house is flush with the outside, then the water from the outside is easy to flow into the prefabricated house.

There are drainage ditches built around the prefabricated house to facilitate our rainwater drainage.

2. The prefabricated house is usually built with color steel sandwich panels, and its solidity is not as strong as the house built of concrete, so when we use the prefabricated house, do not run and jump in the house, and do not use too much force when closing the doors and windows. The types of furniture and articles placed in the prefabricated house shall not exceed the load specified on the floor, etc.

3. After the prefabricated house is built, do not remove the screws and steel plates at will. If the prefabricated house is damaged, we need to contact a professional for repair. The color steel plate of the prefabricated house is easy to rest after being used for a long time, and we should regularly remove rust from the color steel plate and other perishable parts, paint anti-rust paint, etc.

Re-lay the color steel tile at the lap joint, the lap length is slightly longer, and the tile nail is inspected and sealed.

Causes of water leakage:1Due to the large span of the movable board house panel, the lap of the roof panel is difficult to meet the design theory standard due to technical reasons, resulting in rain leakage.

2.In the process of installing the prefabricated house, he did not pay attention to the protection and stepped on the roof at will, which destroyed the flatness of the roof.

3.There is no slope in the transverse direction of the gutter of the prefabricated house, and a certain slope should be left when installing, at least. At the gutter lap joint, there are gaps in welding, leakage welding, slag inclusion or no anti-corrosion.

4.The use of substandard materials or failure to operate in strict accordance with the requirements of the construction specifications in the construction process of the prefabricated house will also lead to water leakage.

5.The construction of key nodes is sloppy. The pipes and vents protruding from the roof are not tightly plugged at the root, and the waterproof layer is not flooding enough. In case of rain, the exhaust groove is blocked, and the exhaust hole is unreasonable, resulting in long-term immersion of the insulation layer.

Houses and other furniture, there are also quality problems, if the construction is high, the draft will be high, the probability of problems will be smaller, but if the construction quality is poor, the service life will be greatly reduced, and even in a short period of time, there will be a variety of problems, such as roof water seepage, which affects both life and interior decoration. So, how to deal with roof water seepage? What are the roofing leakage repair materials?

Let's take a brief look at it together.

1. How to deal with roof water seepage.

First find the part of the water seepage, check whether there are cracks in the roof and connection parts, whether the original waterproof layer is aged, and then remedy it according to the leakage, if it is a prefabricated plate cracking, stick it with asphalt, if it is the original waterproof layer seepage, the situation is serious, the waterproof layer needs to be removed, and the waterproof treatment is redone, the situation is not serious, and a layer of waterproof coating is brushed on the water seepage part.

Second, what are the roofing leakage materials?

1. Asphalt: The use of asphalt to fill the leakage is a method that everyone is familiar with, but because of the black color, unless it is fully constructed, it will leave unsightly traces, and it is accompanied by a pungent smell, so there are fewer and fewer people using it now.

2. Construction glue: If you know the best leakage, the use of construction glue can play a good role in filling the leakage, including neoprene waterproof glue, caulking ointment, roofing waterproof glue, elastic polyurethane waterproof glue, etc., consumers can choose according to the actual situation.

3. Waterproof materials: With the development of science, there are many types of waterproof materials on the market, such as cement mortar waterproofing agent, polyurethane waterproof coating rubber, waterproof heat insulation paint, etc., which are all new waterproof materials nowadays, with a variety of colors to choose from.

4. Waterproof membrane: a wide range of use, whether it is rainwater or groundwater, can play a good role in resisting, and the tensile ability is also excellent, even if the environment is harsh, it can also maintain stable performance, which is one of the most used waterproof materials.

Summary: The above about how to deal with roof seepage and roof leakage materials are introduced here, I hope it will help you. If you want to know more about related information, please pay attention to Qeeka Home.

First of all, it is necessary to eradicate the previous waterproofing, such as paint, membrane, etc., if it is made of mortar Senchapei waterproof, you can not eradicate it. Then repair the leaking place, and after the repaired area is dry and firm, start to do waterproofing. There are two layers of waterproofing, the first layer is flexible waterproofing, and the second layer is mortar waterproofing, which can also protect the flexible waterproofing of the bottom layer while waterproofing, and after the waterproof material is dry, it will not leak.

How to repair the roof leakage house?

Roof seepage can be repaired indoors. It is necessary to drill holes in the leaking gap of the indoor roof first, install the pressure nozzle, and then use a high-pressure pump to squeeze the waterproof material into the leaking gap of the indoor roof until the waterproof material flows out of the gap. This repair method is a technical job, and it is recommended to ask a professional construction team to come to the construction.

How can a roof leak be detected?

If it is a bungalow, the roof is surrounded by sand, and then put water on it, and after a certain period of time, if there is a leak in the roof of the house, it means that the roof is not in order, and remedial measures need to be taken. If it is a high-rise building, find the damage to the roof waterproof layer; Or find the corresponding place on the roof from the leakage in the house, remove the waterproof layer, and see which direction the water flows from to find the leakage.

How to fix a leaky roof?

1. Find the leakage point.

The first step in repairing a roof leak is to find the leak and see if there are cracks in the roof and whether the original waterproofing layer on the roof is damaged. But in fact, this step is the most difficult, because the location of the water leakage in the house may not mean that the corresponding position of the roof has cracks and leakage, after all, the water is fluid, it may be free between the floor and the waterproof layer, so the roof leakage point and the water leakage point in the house are not necessarily 100% consistent.

2. Targeted solutions.

After finding the leakage point, choose different plugging methods according to the different conditions. The most complete way to solve the problem is to repair the surface of the water, open the roof to find the leakage point thoroughly, and then redo the waterproofing, resurface the waterproofing membrane, and replace the rigid roof. This method can ensure that there is no water leakage for a long time, but it is time-consuming, labor-intensive, and costly, and the maintenance cost is high.

Another repair method is backwater repair, which is to apply waterproof glue (commonly known as waterproof needles) to the leaky parts of the house. It's simple and immediate, with low maintenance costs, but it won't last long and will likely leak again.
