If the cement floor is cracked, what to do if there are cracks in the cement floor

Cracking occurs when the ground is leveled, which is a common construction quality problem, which is an abnormal phenomenon, and the reason is that the base is too dry and does not do sprinkling treatment or the temperature is high and the water evaporates quickly and does not do a good job of sprinkling and maintenance.

Whether it may affect the subsequent construction and whether it needs to be rectified needs to be further checked and determined, and the amount of negotiated compensation should also be calculated based on the results of further inspection.

The content that needs to be checked (that is, the aspects that will have an impact on the subsequent construction) mainly includes to see whether there is a problem of hollow drum delamination, if there is a ground crack, there is also a problem of hollow drum delamination, and the place of hollow drum delamination needs to be removed and reprocessed; If there is no problem of hollowing and delamination only cracking, the treatment method is to directly use cement mortar for grouting treatment on the cracked place, which will not have a big impact on the subsequent construction such as the paving of wooden floors.

Detection method: Use a 25g drum hammer (or a small hammer, no drumstick, you can choose a thicker steel rice spoon instead) to knock on the ground for inspection, and listen to the virtual reality of the sound to judge whether there is a hollow drum delamination.

The national building decoration regulations require that the number of hollow drums in a single hollow drum area in the same space is less than 400c and no more than 3 places are considered qualified.

The hazards that may be caused by the hollowing and delamination of the ground: it will lead to cracking, loosening, falling off and warping of the tile finishing layer, and if it is a paved wooden floor, it will lead to floor collapse and unequal height.

Whether it is necessary to deduct the payment: if it is only cracked and no hollow drum delamination, it is recommended to let it be grouting treatment; If the cracking and hollowing delamination exceed the requirements of the national norms and standards, the standard of compensation should be negotiated on the basis of the cost of rectification and maintenance.

It is a shrinkage crack caused by a large temperature difference, and it is not a big problem.

After the ordinary cement is condensed, there are small pores inside, and during the ice disaster, the water penetrates into the cement through the capillaries, and when the temperature is cooled, the water freezes and expands in volume, resulting in the cracking of the cement. Cooling will also shrink the volume of cement, increase internal undesirable stresses, and exacerbate cracking.

Waterproof cement can be used, and steel bars can be arranged inside, and expansion joints can be set to prevent cracking.

The measures are as follows:1Clean up the cracks:

Use a cleaning tool to remove loose material and dirt from the cracks for easy treatment. 2.Use gap filler:

Fill the cracks with caulk. The caulk needs to choose products with good water resistance, weather resistance and elasticity to ensure that the caulk is the same as the ground tone. 3.

Grinding treatment: After the caulk is completely dry, polish the gap of the caulking part and use a handheld grinder next to your best friend for polishing. If the crack is large and requires other professional treatments, such as resurfacing the floor or repairing it with glue first, it is best to have a professional check the severity of the crack before this good reputation oak to determine the best solution.

Floor tile seam opened pro! Hello, I am glad to answer for you <> pro floor tile seam opened 1Cracking caused by exposure to the sun and wind If the crack is shallow, you can buy some floor wax by yourself, buy some color to fine-tune a color similar to the floor, and then wax.

If it is more serious, it is recommended to go to the building materials hardware store to buy caulk for the wood floor (or fill the depression with fine sawdust + water-based silicon likang close to the color of the wood floor), and then smooth it. 2.Cracking of the floor plate If the board is cracked, you can still choose to use filler, but if the quality is serious and cannot be repaired, you need to contact the manufacturer for partial replacement.

3.Cracking at the joints of the floor in autumn and winter The weather is cold in autumn and winter, everything follows the principle of thermal expansion and contraction, and the floor is not excluded, in the cold season, the floor will also shrink, but this gap will be very small, and it will return to its original state by itself as soon as the autumn and winter passes. 4.

Cracking in the dry season. In the dry season, the wooden floor will also be because the air is too dry, the moisture will be dismantled, resulting in cracking, at this time, do not rush to repair, even if it is repaired, it will continue to crack, and then repair it together. Hope mine can help you <>

Do you have any other questions?

Gaps between the concrete floor and the wall are common, which not only affects the aesthetics but also can lead to problems such as wall leakage. Here are some workarounds:

1.Use a gray or white elastic caulk. Caulk fills the gap between the source plate and the wall, providing some elasticity and stability.

You can choose a caulk that is similar in color to the floor or wall, which will allow you to better hide the gaps. Caulk can be used manually or with specialized aids such as Zenavu caulking tools or tape laying machines.

2.Apply paint to the crevices. You can use a paint similar to the color of the floor and wall and apply it to the gaps, which will cover them well and enhance the aesthetics.

3.Use advertising tape. Choosing a similarly colored, particularly thick advertising paper tape to stick to the gap can make the gap no longer so obvious, and it is not easy to fall off.

Please note that if the gap is large or you need to carry out more complex repair work, it is advisable to seek professional help or consult an estimator. This ensures the effectiveness and quality of the patching work.

What to do if there is a crack in the wooden floor, first distinguish whether it is a solid wood floor, or a laminate floor, the cracking of the laminate floor is relatively less, if there is a crack is generally a quality problem, it is not good to repair, but you can find the manufacturer to make a claim, the cracking of the laminate floor is not good to repair, and there is no need to repair. If the solid wood floor is cracked, it is divided into several situations, excluding whether it is peeling, or the substrate is cracked, it is really practical under what circumstances, whether the house is too dry, if the substrate is cracked, it can be repaired if it is not serious, cracking is more common in the northern winter, because the north is too dry, it is recommended to put a few basins of water in the house, nothing to use the tide to mop and wipe the floor, the cracks in the wooden floor are generally at the end of the wooden floor, easy to find; However, when the wood floor is cracked, the crack is not easy to measure, and the crack is slender and not easy to find; When the wooden floor arches or the tile becomes hot and expands and contracts, it will cause the wooden floor to squeeze and crack, which mostly occurs at the root of the notch of the wooden floor. Repair of cracks in wooden floors 1, repair of cracks in the surface paint layer, first gently polish the worn places with sandpaper, remove the dirt, and then wipe them clean with dry and soft cloth keys, re-coat, or paste polyester film.

2. For the cracking repair of wood floor panels, if the cracking is relatively light, you can use some mixture to fill the floor cracks (such as using caulk to hook the joints); If the cracking situation is more serious, the only way to solve it is to replace the cracked part, and the consumer can contact the manufacturer to buy the required model for repair. 3. If the gap between the floors is repaired if the gap between the floors exceeds 2mm, it needs to be repaired, and the dry shrinkage is less than 2mm, and it will return to normal after autumn and winter. In severe cases, the floor should be completely disassembled, resurfaced and part of the floor replaced as appropriate, and expansion joints should still be reserved to prevent the floor from expanding when wet.

If you want to repair cracks in cement floors, you need to clean the cracks, mix cement, repair, tape, reapply, and apply edges. The details are as follows:

1. Clean up cracks. Scour the inside and around the crack so that the internal residue and floating ash can be washed away.

2. Stir. The cement pavement repair material is mixed with water according to the standard, and then stirred, and when the water and the repair material are fully mixed evenly, it can be repaired.

3. Repair. Once the materials are ready, you can start tinkering. Apply the stirred material evenly to the cracks and fill the cracks with the repair material.

Generally, the repair material is solidified quickly, so it should be faster in the repair process, so as not to dry out before the crack is filled, resulting in a gap at the bottom of the crack.

4. Adhesive tape. In order to ensure the aesthetics after repair, the two sides of the crack are fixed with adhesive tape after repair to prevent the repair material from overflowing.

5. Reapply. After gluing the tape, you don't have to worry about the problem of raising the ground due to the large amount of repair materials, and apply it to both sides until the ground is flat. Once leveled, it's time to remove the tape.

6. Apply the edges. Apply the material that repairs the crack evenly around the crack so that the crack and the ground are integrated.

Notes:

1. The quality and performance of the repair material directly affect the repair quality and efficiency of the cement floor matte surface, there are many types of cement pavement repair materials on the market, but these materials may not be able to meet the requirements of the quality and efficiency of the ground repair at the same time. If the right materials are not selected, it is difficult to meet the quality and efficiency of disease repair.

2. Generally speaking, when the cement pavement peels, drops, potholes, etc., it is often repaired with high-grade cement concrete, but the result is often that it will all fall off after a period of time after repairing, because the cement cannot be used to repair cement, the reason is that the adhesion and stability of cement are not enough, and these two indicators are also the main indicators to measure whether a certain repair material is qualified and useful.
