What are the causes of uneven ground and what are the solutions?

The reason for the uneven ground may be that the mortar is too thick, the cement mortar floor is hollow, and the surface of the base layer is not clean. The solution is to grind and level the cement floor with a flat grinder, or walk and grind independently.

It may be because the mortar is too thick, or because the cement is not stable or it is hot cement that has just come out of the kiln. The solution can choose to use stone mud, gypsum and white glue for leveling, or you can choose to use cement and sand for leveling.

It may be the rainy season, the ground is damp, and then the ground is uneven, you can use a special mixed mortar to level, this mixed mortar is specially used to level the ground, but it can also prevent dampness, but it contains a certain amount of glass filament, so that you can prevent the ground from bubbling and cracking in the future.

Excessive mortar thickening is an important cause of uneven ground. If the ground is uneven, you can use a floor grinder to grind and level the cement floor.

The reason is that the mortar is too thick, the process is not neatly arranged, and the quality of the cement is poor.

The mortar is too thick or the cement is not stable, and it is the mortar that is too thick or the cement is not stable, which is the reason for the instability of the ground. It can be leveled with cement and white glue.

It is because it has been crushed by various heavyweights and has been used for people to walk for a long time, so the ground will be uneven, and it can be properly sprinkled at night for him to absorb.

The first is that the mortar ratio of concrete is improper, the second is the uneven pounding during construction, and the third is that the selection of materials is not up to standard. Repair with cement mortar, or repair with cement and sand configuration, repair with grout, mainly for low-lying ground.

The unevenness of cement, the connection of new and old concrete, the protection and moisture-proof treatment of concrete surface, and the repair treatment of concrete sanding base layer.

There are reasons such as excessive mortar thickness, improper process arrangement, and unclean surface of the base layer. The solution is to apply tiles and fill them with machines.

The floor tiles are uneven, generally caused by the fact that the floor tiles are not burned through, so that there will be a warping angle of the floor tiles, most of the manufacturers use heated materials in order to save costs, and the internal materials are not completely digested in the heating process, so they will be deformed and warped, and then they will cause unevenness when they are paved to the ground. Of course, it should also be considered that it is caused by the incorrect direction of the floor tile paving, some workers are more lacking in technology, in the process of paving, do not pay attention to the direction indicated by the floor tile, and do not prompt on time to pave, so that the joints at the corner are not neat, and at this time there will be an unequal situation of floor tiles.

In the process of paving the floor tiles, the cement and sand are generally mixed to pave, at this time the specific gravity of cement and sand is very important, if the specific gravity of the sand is too high, it will cause the floor tiles to stick, and the floor tiles are upturned up, in addition, the floor tiles are not knocked around after paving, so that the surrounding sediment is unevenly stressed, so as to cause the floor tiles to be particularly uneven. In addition, due to the influence of the surrounding environment, if the temperature is too low, it will cause the moisture in the mortar to be too high, so it will cause the situation of freezing, this time will destroy the strength of the cement mortar, after this situation, the floor tiles can not be well combined, for a long time, the floor tiles will be uneven, and the high temperature environment will also lead to the deformation of the floor tiles.

In fact, in the whole decoration process, the paving of floor tiles is a very important process, we must observe in time, find that the situation is not right, to put forward in time, and to check whether the joints are smooth, whether the use of cement is uniform, once the problem is found, to find workers in time to solve.

It may be because the floor tiles are uneven before they are laid, or it may be because of thermal expansion and contraction, and the floor tiles bulge.

It may be because you have laid the floor tiles in the winter, so it has become this uneven situation, and secondly, it may also be because you have not hired some professionals, or when you are laying floor tiles. The ground is not particularly flat, which is why this phenomenon is caused.

The floor and wall of the rough house are directly laid with cement, and the uneven cement floor is encountered during the decoration, and it needs to be dealt with in time, so how to deal with the uneven cement floor? If the problem of uneven cement floor is not dealt with well, the residential ground will still be uneven in the future, and what are the solutions to uneven cement floor?

1. How to deal with uneven cement floor?

The old ground that has been used, or the ground has potholes and damaged ground, it should be repaired in time, and the construction should be carried out after leveling before using putty coating.

1. Create a suitable surface roughness and improve the adhesion of the coating, relying on the interaction force between the acute groups in the floor paint and the surface molecules. Mechanical teeth and actions can be used, floor sanding, sandblasting. Its surface will also become rough, improving the adhesion of the coating.

2. The old coating treatment problem, generally can be considered to retain the old coating that has not failed, so as to further enhance the overall protection ability of the coating, if the construction coating for the purpose of decorative effect, the old coating should be completely removed, or the old coating should be thoroughly polished, and then scraped and leveled putty to ensure the flatness of the base material by percent.

3. Treatment method: (1) first use a grinder to polish the cement floor;

2) Use a shovel axe to remove the surface layer of the cement floor with hollow drums;

3) Use high-strength cement or epoxy mortar to repair and level the floor position obtained by the tunnel with potholes;

4) Carry out construction according to the normal resin coating process.

2. What are the solutions to uneven cement floors?

1. Gypsum leveling, advantages: this method can be used for local leveling, the ground does not need to be raised, the leveling thickness is about 5 20mm, there is almost no impact on the height of the room, the drying speed is fast, and it will be relatively cheap and convenient for construction. Applicable Environment:

The flatness of the room is slightly better, the floor is more silvery smooth, and there are local uneven places.

Disadvantages: It can only be used for leveling in a small area.

2. Cement mortar leveling, advantages: This leveling method is suitable for all kinds of ground, all kinds of ground leveling before laying the ground. Applicable environment: the house is raised high, the radiator is heated, the solid wood floor is leveled before laying, and the composite ground is leveled before the front source is laid.

Disadvantages: the leveling thickness is too thick at 25 35mm, if the cement mortar ratio is not right, the surface layer will be pulverized and sanded, ash and cracked. The floor (laminate flooring) forms some gaps with the screed, and when people step on it, the dust on the ground is dispersed and dispersed, and then escapes from the expansion joints.

It spreads out through the gaps in the baseboard, forming a phenomenon of dust. In addition, the cement mortar is not leveled in a detailed place, and there will be a hollowing phenomenon.

How to deal with uneven cement floors? When the cement floor is uneven, it is necessary to level it first, and what are the solutions to the specific uneven cement floor, which are also clear after reading the relevant introduction of this article. Remember to be sure to lay tiles and other treatments after the cement floor is uneven, and do not directly lay tiles on uneven ground.
