Can a leak on the top floor be re layered with reinforced concrete?

Theoretically, cast-in-place slab roofing is possible, but it is only possible. Even if the structural calculation allows the addition of concrete, it is very troublesome, and it is labor-intensive, time-consuming, and too cost-effective.

The reason is: the specific method is to remove the original insulation and waterproof leveling layers, remove the surface of the original roof panel, clean, reinforce, and pour 40 mm thick waterproof concrete (this can cancel or reduce the number of waterproof layers). As the thickness of the plate increases, the bearing capacity is correspondingly increased, and the increased load is digested.

It can also be picked on the original roof panel for tooth-shaped shallow grooves, cleaning, reinforcement, pouring 40 mm waterproof concrete, and forming a laminated plate with the original concrete. In this way, the carrying capacity will increase even more. Solved the problem of waterproofing and the bearing of the plates.

But because the roof load has increased by about 100 square meters of the wall, the load on the beam, wall, column, foundation has also increased, and it is necessary to check.

When the original building was designed, the strength of the wall was generally rich. After a few years of use, the settlement is mostly completed, and the endurance of the ground base will increase. There is potential to be tapped, and the strip masonry foundation of multi-storey buildings is generally not too problematic, but the bearing capacity must be checked. Ferroconcrete.

Beam and reinforced concrete slab foundations are at risk of insufficient bearing capacity, so special attention should be paid to them.

Through the above analysis, it can be seen that through structural calculation, beams, walls, columns, and foundations can meet the bearing requirements best, and when the requirements are not met, the beams, walls, columns, etc. can be reinforced, and there is basically no good way to do the plate foundation.

So the best solution is to find a way on the waterproof layer. It needs to be said that the roof is waterproof.

It's a bit of a hassle to check for leaks, so be careful. Once the roof leaks, the insulation layer below is generally inspected and treated, especially the traditional perlite.

and other bulk material insulation layers, if necessary, they should be dried or replaced. In order to prevent condensation and long hairs on the interior wall or shed surface caused by thermal insulation problems.

A new layer of concrete, after a few years of leakage, and increase the weight of the house, it is recommended to do waterproofing, or to do a sun room, <>

The leakage of the top floor generally only needs to find a professional waterproof master or institution to operate, as long as it is done well enough, it is generally able to achieve quality assurance for about ten years.

1. It is not necessary to pour a new layer of concrete, one is to increase the load, and the other is that the roof is usually shared by several households, and it is impossible to pour all of them.

2. You can make another layer of waterproof layer to solve the problem.

If the source is not solved, the stagnant water will only spread between the interlayers.

Summary. But the premise is that the original roof must be covered with a waterproof membrane. Add 50 mm thick fine sand on top, and then use 8 0 100 mm thick reinforced concrete. Even the cracks on it won't leak rain.

If the roof leaks and the rain does not hit the original roof, is it okay to put a layer of concrete on it?

Dear, if the roof leaks and does not smash the original roof, it can be done with a layer of concrete.

But the premise is that the original roof must be covered with a waterproof membrane. Then add 50mm thick fine sand on top, and then use 8 0 100mm thick reinforced concrete to sing the ruler. The bridge is high and the cracks above it will not leak rain.

But the premise is that the original high roof of the wild bridge must be paved with a waterproof membrane on the air. Add 50 mm thick fine sand on top, and then use 8 0 100 mm thick reinforced concrete. Even the cracks on it will not leak the rain.

Before the roof is waterproofed, the ground needs to be cleaned first, so that there are no impurities and no dust, and the cement binder needs to be configured.

It is also necessary to check whether the roof is flat, do the treatment of slope finding, and install the extension slip joints with the key mold wax. Next, use cement to do leveling, and also need to do two calendering treatments to make the roof surface more tight and strong. At the same time, the corners of the roof should be coated with cement mortar.

I don't know what you mean by "don't smash the original top". However, in order to completely solve the problem of roof leakage, it is generally necessary to deal with the following requirements:

1.Clear the roof construction layer to the roof cast-in-place slab, and clear the parapet around the roof at the same time.

the stucco layer to the surface of the masonry;

2.Wash the surface of the roof panels and parapets. If there is obvious water leakage at the bottom of the slab at this time, it proves that there are cracks in the roof panel, and the cause and nature of the cracks should be found out first, and whether there are potential safety hazards.

then take measures to close the crack (e.g. by grouting); If there is only a watermark on the bottom of the board, it proves that the roof panel only has micro-cracks, and no special treatment can be made.

3.Full brush plain cement slurry, no missing brush, especially the corners;

4.According to the requirements of the product manual, the waterproof agent or waterproof coating should be fully brushed, and the brushing should not be missed, especially at the corners;

5.According to the design requirements, the construction of each roof structure layer is completed in turn.

Removing the roof structural layer to the roof cast-in-place plate is mainly used for two purposes, one is to find out the cause of roof leakage and take corresponding measures to eliminate; The second is not to increase the load of the roof.

weight). Hope it helps.

Above the top in a layer of concrete can be.

If the waterproofing is not in place, it may lead to water leakage on the roof in the later stage, and the floor slab in the home will have the problem of water seepage. So if the roof leaks, do you want to make another layer of cement?

1. Not recommended.

2. Because the strength of the cement mortar is not particularly high, the waterproof will also take effect, and it will not take long for the problem of water leakage.

3. The best way is to re-do the waterproofing on the roof and brush the waterproof material to effectively avoid water leakage again in the later stage. Although it is a bit troublesome, it will solve the problem of water leakage once and for all.

About the roof leakage and another layer of cement, it is introduced here, I hope it will be useful to you.

The top floor is brick concrete all cast-in-place, and there will be water seepage problems on the cast-in-place surface, but the water seepage rate is not large, and the problem can be repaired generally. Whether there will be water leakage depends on whether the waterproof layer is done well, and the general building will do a good job of waterproofing and thermal insulation. The top floor has both advantages and disadvantages, with good ventilation and good lighting.

The waterproofing of concrete roofing is actually more particular, if it is a membrane, the cost is low, but the waterproof effect is defective, and the base can not be in contact with zero distance.

1. When the weather is sunny (the orange base crack cannot be repaired when it rains), first clean the crack and the surrounding sand and debris.

2. Build a stove with bricks, put the iron bucket filled with asphalt on it (you can't use a plastic bucket, the asphalt boils at a very high temperature), and use firewood to melt the asphalt.

3. Wear gloves (pay attention to safety, the temperature of the asphalt is very high), pour the molten asphalt into the crack with a spoon, and fill the gap slightly higher than the ground suitable. When the asphalt solidifies, it will not seep into the future.
