How to repair the roof of a bungalow so that it does not leak?

It is necessary to do some waterproof work on the roof of the flat-roofed house, only in this way can we ensure that the flat-roofed house does not leak.

You can do a layer of waterproofing on the roof, our hometown will iron a layer of asphalt on the roof, the waterproof effect is very good, and there is no leakage at all.

In order to prevent water leakage in my grandmother's bungalow, I built a roof made of tiles on top of the bungalow, so that it can be left in the waste water tank when it rains or snows, which is very convenient.

Shovel off all the peeling and weathered base surface of the roof of the bungalow, see the hard bottom, and then clean it up, there can be no debris, dust or debris will affect the waterproof effect of the waterproof material.

Brush the base surface that needs to be repaired with waterproof coating, and then brush the second time after the first dry, note that the thickness of the polyurethane waterproof coating should not be less than 1.5mm, and the more reliable thickness is 2mm.

In the southern countryside, there will be water leakage in the bungalow on a rainy day, which is very common in the south, because the bungalow is basically a cement mortar layer, which is easy to cause leakage because of the weak crack resistance after the foundation sinks and the thermal expansion and contraction of the foundation.

The best way to fix a leak in a bungalow is to re-surface the roof with waterproofing membrane.

1. Causes of water leakage in home improvement waterproof construction:

The quality of home waterproof construction depends on the material for three points and the construction for seven points. A lot of water leakage is caused by improper construction, especially after doing a good job of waterproofing, measures should be taken to prevent the subsequent construction of the damage to the waterproof layer. The main causes of water leakage in the bathroom at home are:

1. Cracks in rubber concrete.

2. Use of bad waterproof materials (cheap but not good).

3. The waterproof layer is not made according to the requirements or the thickness of the waterproof layer is not enough ( .

4. When doing waterproofing, the base surface does not meet the requirements, and there are phenomena such as sand and looseness.

5. After the waterproof layer is made, the waterproof layer (veneer brick) is destroyed in the subsequent process.

6. Decoration slotted buried pipe destroys the original waterproof layer and causes water leakage.

7. Only do waterproofing around the holes such as pipes and floor drains, and the water will penetrate into the tiles and tile splicing joints on the ground in the case of bathing, and leakage will occur.

Attention should be paid to the process of repairing water leakage in the house

When the polyester cloth is constructed, the construction environment temperature should not be lower than 5, and it is strictly forbidden to construct under the conditions of rain, snow, fog and five-level wind and above.

The base must be firm and flat, there shall be no unevenness or serious cracks, when inspected with a 2m ruler, the gap shall not exceed 5mm, the depth of the pit shall not exceed 3mm, all holes and cracks shall be filled with mortar, and after standing for 3 4 hours, the base layer and the polyester cloth can not be seen on the watermark.

The base layer should be cleaned before the polyester cloth is paved, and there should be no floating ash.

The selection of the base treatment agent should be compatible with the material properties of the polyester cloth, and the spray should be uniform.

Based on the principle of "bottom first and then departure, first far and then near", the nodes and drainage parts should be concentrated first.

The polyester cloth should be smooth and straight, the lap size should be accurate, and it should not be twisted, and the polyester cloth lap part should be overflowed with hot-melted modified asphalt as the degree, and then the interface should be scraped.

Pipelines, equipment, and embedded parts should be installed before the construction of the polyester cloth, and it is strictly forbidden to drill holes or place sharp and hard heavy objects on the waterproof layer of the polyester cloth.

Answer: Using 502 cement glue is a better repair method. Now many people are trapped by roof leakage, all hope that good leakage materials, easy to use, simple construction, durable, in fact, there has long been such a 502 cement glue, it is specially used to fill the leakage of the roof, to ensure ten years without leakage. Because of its elasticity, it solves the problem of cracking caused by thermal expansion and cold contraction of cement.

It is nothing more than to make waterproof glue.

The first is the most affordable.

It is to buy oil cake to boil it yourself, brush a layer of oil cake on top of the flat roof, the second is to buy waterproof glue directly, brush a layer of waterproof glue on the surface, the third is to buy cow felt, spread a layer on it, just fine.

1. Cleaning: First of all, the cement caused by weathering should be cleaned up, and then the dust should be cleaned up, and there can be no debris to cover it, so as to avoid affecting the effect of leakage.

2. Repair: For the place where the crack is relatively large, you can use cement to refill it firmly and strongly, if it is weathered in pieces, you can first remove the weathered cement layer, and then smooth it with cement mortar.

3. Leak filling: After the filled cement is dry, you can add anti-seepage filler to sprinkle it on the base surface of the roof shed, and then use a wooden board and scraper to push it open to cover the entire roof.

4. Curing: 12 hours can not be washed with open water, soaked, and after 72 hours of anti-seepage filler is completely penetrated and solidified, the best effect can be carried out at this time.

Roof leakage has always been a very common problem, such as water leakage caused by non-standard construction, or water leakage caused by waterproof engineering, and different roof leakage treatment methods are different. Today, I will take you to understand the best repair method for roof leakage in bungalows, and the best way to repair roof leakage in the relevant content, I hope it will help you.

The best way to repair a leak in the roof of a bungalow

The best way to fix a leak in a bungalow is to re-surface the roof with waterproofing membrane. Removing the failed waterproof layer of the roof, or laying waterproof membrane directly on the roof, can fundamentally solve the problem of water leakage, and at the same time try to set up certain drainage facilities on the roof.

Bungalow leakage is generally due to poor roof drainage, or cracks in roof building materials, we had better fully inspect some bungalow leakage location, leaking bungalows often have certain safety hazards. After checking that there are no potential safety hazards in the bungalow as a whole, the bungalow can be repaired, and the roof can be paved with waterproofing, so as to completely solve the problem of water leakage in the bungalow.

Roof leakage is best treated within the leakage method

If the effect is not good, the waterproof project should be carried out by the water surface of the roof, and the solidified grout will be evenly added to the concrete cracks of the ceiling through the high-pressure pouring machine, so that the grout will quickly penetrate and diffuse in the gaps, so as to achieve the effect of filling, and can also disperse the water vapor and air in the ceiling, so that the slurry and the floor slab become a whole, so as to achieve the effect of waterproofing.

How to waterproof the roof?

1. Before construction, it is necessary to ensure that the roof is flat, dismantle the cherry blossoms and clean them up to ensure that there is no dust and garbage, and fully configure the cement binder according to the corresponding proportion.

2. Then level the roof, and set the expansion joints in place, and then do calendering treatment, so as to ensure that the outer layer of the roof becomes strong and durable.

3. After the trip, take cement mortar to connect the waterproof layer with the additional layer, and ensure that the width is 10 cm, and the spacing of the waterproof layer will not be less than 5 cm.

4. Then lay the waterproof membrane, pour the configured cement adhesive on the surface of the roof, and then use the scraper to apply the balance, and then spread the membrane forward to squeeze out the internal gas and extra binder.

5. After the laying is completed, another layer of cement mortar protective layer should be made on the outside of it, with a thickness of about 2 cm, and finally sprinkled with water for curing.

The best way to repair the roof leakage, the best way to repair the roof leakage, the best way to deal with the leakage of the roof, will take you to understand here.

1. Repair, most of the leaks on the top floor are cracks, fill the cracks with glue, and then repair them next time after drying, if the joints are less than 1mm, there is no need to repair the leakage.

2. Carry out two all-round brushing with water-based waterproof paint or breathable and breathable waterproof materials, and the width of the seam should be more than 20 cm if the light coating is light. This ensures adhesive properties. The waterproof coating is all penetrated and bonded, with good elasticity, so the life is very long, pay attention to the 12 small slag digging can not be wet by rain; If the roofing material is special, such as rubber, which is not suitable for waterproofing, other waterproof materials can be selected.

For example, if there are no cracks on the surface of the tile, the waterproofing agent can be used for the waterproofing of the surface, and the cracks are covered with leakage paste for composite waterproofing.

3. The leakage place on the roof is usually the shape of the spout, joints and other parts, and these details must be paid attention to during construction in order to be safer.

4. If you don't know how to use it, it's best to ask a professional to repair it.

Waterproof materials are optional. If there are potholes, they can be filled with cement mortar, or they can be treated with reinforced mesh concrete for interface treatment, and then covered with waterproofing membrane. Pay attention to the seams between the waterproofing membranes to ensure a seal.

Most of the leaks are cracks and must be filled with leaking sealant. Then proceed to the next step. If the crack is less than 1 mm, there is no need for a leakage seal.

If the water repellent is placed on the surface of the tile and does not continue to fall through the gaps, then the surface can be waterproofed with a water repellent and a leaky patch can be applied to the joints.

The wall seepage treasure is made of water-based or light-transmitting waterproof material, which should be applied twice. If the gap of the light film is large enough, it can reach 20 cm. This guarantees adhesion.

It has good elasticity and long service life. Be careful not to get wet in the rain for 12 hours; If the roofing material is special, you can choose other waterproof materials.

Some old-fashioned flat-roofed houses, the building materials are not particularly good, and the roof will leak when it is windy and rainy, which makes the house very bad, what should we do?

If the scope of the leakage is not particularly large, but only a small joint, you can choose bricks and wood to shield them.

If the range is relatively large, choose plastic cloth to cover, plastic cloth can play a good role in waterproofing.

If it is a little more powerful, you can choose asphalt for repair, spread a layer of asphalt on the roof, cover the asphalt with plastic sheeting, and protect it with two layers.

Some discarded billboards can also be covered on the roof for protection.
