Why does underfloor heating make some tiles bulge?

Why does underfloor heating make some tiles bulge? Nowadays, more and more families like to lay floors on the ground, even if the home is floor heating, like the foot feeling of the floor, with the floor heating floor, it can also achieve the thermal conductivity effect of tiles. But there is a situation that wooden floors are prone to bulging, so why do they bulge?

Is there a way to avoid it? Let's give you an answer!

Why does underfloor heating make some tiles bulge? First of all, let's understand the reason for the deformation of the floor, one of the biggest characteristics of the floor is that it cannot touch the water, no matter how waterproof the floor, it is a wooden material that will deform and bulge when it touches the water, the floor is so, and the door is the same.

In fact, it means that the floor is afraid of moisture and water, and once it is soaked in water for too long, it will cause expansion and deformation, so it will bulge and warp and so on.

When installing the floor, you must remember to leave the expansion joints, if you don't leave or leave too narrow, the weather changes hot expansion and cold contraction, if you don't leave enough, it will cause warping, and the floor will arch up and deform.

When transitioning between several spaces, the floor must be buckled, and the floors of the two spaces will also expand and squeeze each other when the weather and temperature change, which can also deform the floor. So it's better to add buckles.

So how to avoid it? The first floor should be dry, if it is an old floor that has been soaked in water before, please do not continue to use it, and the wooden floor that has not been soaked in water should also be kept dry, and the water content should not exceed 12%. Keep the ground very clean before installing the floor, if the ground is not brushed, then please lay a mulch, because the low version of the seam, if the ground is not clean, there will be dust shuttled between the gaps, affecting the effect of the seams, and the interior is not easy to take care of.

Remember to reserve the expansion joints on the wall, remember to add buckles when separating the room, and set up ventilation holes, so that air circulation is also very helpful for the maintenance of the floor. If you accidentally splash water, clean it up as soon as possible, if there is a crawling baby, you don't wear diapers in summer, then please put on a mat

It may be because of the principle of thermal expansion and cold contraction, if the temperature is high, the tile will expand.

Because underfloor heating generates a lot of heat, which makes the tiles expand and deform, and the quality of some tiles is not very good, underfloor heating will make some tiles bulge.

Because these tiles are hollow when they are laid, and there are no gaps, they will bulge.

In the process of tiling, the ratio between sand and cement must be reasonable, and it is best not to use too fine sand to lay tiles, because the water absorption rate of such sand is too high, and it cannot retain water, and then the tiles will appear hollow. And when laying floor tiles, the dry paving method is generally used, and the ratio between sand and cement is about 1:4, if the ratio is too large or too small, the tiles will be easy to bulge.

And the householder must buy some of the best when buying tiles, if the material of the tiles is not the same, the heating expansion is not the same, and the use of floor heating will bulge.

There are many reasons for floor heating to cause tile hollowing, the first is that the thermal expansion and contraction lead to drumming, because the reserved gap between the tiles is too small, the floor heating is turned on and the heating causes the tile to expand and squeeze the bulging phenomenon; The second is that the ratio of materials is unreasonable, the ratio of sand and cement in the construction process of porcelain drills is unreasonable, resulting in poor adhesion between ceramic tiles and the ground, and there will be a bulging phenomenon when heated; The third is that the ground level is not leveled during construction, resulting in uneven ground height, and it is easy to drum up after a long time.

It may be that the floor heating pipes under that place are more concentrated, and the heat is large, which causes the temperature in that place to be high, or it is also possible that the bottom layer is not cleaned when laying tiles.

It may be caused by thermal expansion and contraction, and sometimes the floor heating will raise the temperature of the tiles, which will cause the tiles to squeeze each other.

It is because the tiles are not pasted well, there are no gaps when pasting, or the bottom layer is not dealt with well, and then there are problems with the technique when pasting tiles, and there is no attention to maintenance after pasting.

Floor heating will make the tiles on the floor bulge, which is a common quality problem, there are many different reasons for this situation, but these reasons are directly related to the paving of the tiles, so it is said that the tiles are bulging up because the tiles are not pasted well, this is a correct statement, if you want to avoid this situation, you must understand the specific reasons that lead to it.

First, there is no seam left in the tiles

Floor heating will be like this, some tiles bulge up may be the construction personnel did not leave the due gap according to the regulations when pasting the tiles, that is to say, when laying the tiles, a seamless paving method is adopted, which will make the tiles and tiles tightly glued together, but in the winter heating, under the effect of floor heating, the tiles will be affected by thermal expansion and cold contraction, and the gap between them can not support its expansion and contraction, which will cause the floor tiles to bulge, and in serious cases, it will also cause the tiles to crack and warp.

Second, the tile base layer has not been dealt with

When the tile is not handled, it will also lead to the difficulty of the construction site, and let the tile bulge up in the future, because when the floor tiles are paved, the base should be cleaned up, and the floating dust should be removed, and the ground should be sprinkled with water, all of which can be paved after the head of the person, if the water loss of the base is too fast, it will affect the adhesion between the tile and the base will cause the tile to be preheated and then the catch will also cause the tile to warp.

Third, there are problems with the technique of tiling

When pasting tiles, there is a problem with the technique is also an important reason why the tiles will bulge up after encountering the clerk, because the construction personnel need to follow me when pasting the tiles, and the cement and mortar they brush are not in place, or they fail to plaster at any time, which will lead to insufficient adhesion between the tile and the base layer, and it is easy to warp and hollow after preheating. The tiles on the ground should be sprinkled and cured after pasting, at least about 7 days of maintenance, but some construction units in order to rush the construction period after the completion of the paving directly handed, this practice is wrong, and it will also make the tiles on the ground hollow and warped when heating.

Underfloor heating can cause tiles to swell, especially when heating. Many people wonder that this situation is caused by what went wrong during the renovation process. Thermal expansion and cold contraction lead to expansion.

When we carry out tile paving construction, because the gap between the tiles is too small, the ground is relatively dry, and it is easy to cause bulging after heating.

During the construction process, the mix ratio of sand and cement does not meet the reasonable requirements, which will also lead to poor adhesion between the tile and the ground. If we use a lower cement grade and add more sand, the cement underneath will not be able to bond the tiles over time. If our original ground is relatively smooth and the ground is not roughened during tile construction, then it is also easy to cause the tile to arch and bulge.

When we lay tiles on the ground, when the newly laid tiles and concrete are not completely dry, if we are stepped on, it will also lead to weak adhesion between the tiles and the ground, and it will take a long time to arch.

When the tiles are constructed, there must be expansion joints between the tiles, generally about. In fact, there are some special clips where we buy tiles now. When laying bricks, we can use it directly.

For the building materials we use, we had better buy from brand manufacturers, and the cement grade should not be too high. 325 Recommended model for summer. If the indoor temperature is low in winter, we can choose 425 according to the actual situation

In this way, the cement does not set too quickly and avoids hollowing.

When using sand, especially when laying floor tiles, you should not use too fine sand. This will lead to high water absorption and inability to retain water, resulting in hollowing of tiles. Usually, we choose the dry paving method to lay floor tiles.

The ratio of sand to cement is usually 1:4. If the proportions are too large or too small, there will be a void.

Consider leaving a gap of up to 2mm between tiles to reduce tile bulge due to thermal expansion and cold shrinkage.

Yes, it is because the tiles are not pasted well, and it is also because the temperature in the home is too high, which leads to the hollowing of the tiles.

Yes, the quality of some tiles is very bad, there will be thermal expansion and contraction, and it is also possible that the ground is uneven, and eventually such a situation will occur.

It may be because there is no gap when sticking the floor tiles, resulting in no expansion space, so it will be hollow.

Bulging tiles are an anomaly, and if left unattended, they may crack and even pose a threat to personal safety. Therefore, when the tiles have been bulging, the problematic tiles can only be removed and re-laid. In order to avoid the same problem again in the new tiles, it is necessary to carry out the construction in strict accordance with the specifications of the tile paving, leaving enough expansion and contraction gaps, in addition, due to the particularity of the floor heating itself, it should also be added to the necessary place to add heat insulation treatment materials.

The treatment method of floor heating tile bulging is: only to disassemble the tile and reinstall the tile, only in this way can the problem be completely solved. Remember to add expansion joints and expansion edges to prevent the tiles from bulging up when new tiles are added.

If the tiles with underfloor heating bulge up during the process of family living, it is likely that the floor heating is caused by the floor heating, and in this case, the floor needs to be renovated again.

Summary. 1. If you find that there is a hollow drum on the edge of the tile, you can carry out watering treatment (use a small shovel to break the gap between the tiles, and then pour the cement into the gap with water, and the hollow drum will automatically suck it in until it is filled and solidified), so as to avoid overall replacement. 2. A small amount of local hollow drum appears on the tile of the local hollow wall and floor, such as without affecting the stable installation of furniture and household appliances such as cabinets, mirror cabinets, showers and water heaters, it can not be treated, but if it affects the installation and daily life, it is recommended to knock off the local tiles and re-pave 3 area hollow drum is recommended to be removed and re-paved, at this time the adhesive used in the paving is particularly important, if the tile area is small, you can use the beneficial cement, it is stronger than the cement adhesion; A single tile is pasted on a flat plane, you can use tile adhesive tile adhesive, if it is a small area of multiple tiles, it is recommended to use cement is more appropriate than the use of cement.

1. What is going on with the bulging of floor heating tiles 1. Thermal expansion and contraction lead to bulging When laying tiles, because the gap between the tiles is too small, the ground is relatively dry, and it is easy to bulge after heating. 2. The material ratio is unreasonableDuring construction, the proportion of sand and cement does not meet the reasonable requirements, which will also lead to poor adhesion between the tile and the ground. If we use low-grade cement and put more sand, the cement in the lower layer will not be able to bond the tiles for a long time.

3. If the original ground is relatively smooth, the ground is not brushed when we build tiles, which can easily lead to tile arching and bulging. 4. When laying tiles on the ground if the maintenance is not good, when the newly laid tiles and concrete are not completely dry, if we step on it, the combination of tiles and the ground will be very weak, and arching will occur after a long time.

The treatment method of the hollow drum should be combined with the specific situation of the hollow drum to do the corresponding treatment, specifically, there are the following three aspects:

1. For a small amount of ground corner hollow drums (the number of corner hollow drums does not exceed 5%), 108 glue can be added to cement slurry for grouting treatment, and the ceramic tile situation can play a certain role in the floor tiles; A small number of corner hollow drums on the wall (the number of hollow drums does not exceed 5% of the total), the hollow drum area accounts for less than 10% of the area of the tile, it is recommended that you do not need to deal with it, and when it comes to punching and fixing in the later stage, you should avoid the corner hollow drum area.

2. It is recommended to replace the tiles after the center hollow drum is smashed. Replacement method: smash it from the middle, carefully pry it around, generally it will not affect other tiles, if it is a wall and ground that needs to be waterproof, after the tiles are smashed off, it is necessary to use the plugging spirit to paint it.

Loosening can be treated with grouting, which has been bulging up is not only loose, but affects both the use and the visual effect, and must be re-dismantled and paved, and there is no other way.

I hope my answer can help you.

Floor heating is paved with tiles, and it is rare to see bulging, because it is most suitable for floor heating, and the paving material is a variety of large-scale floor tiles, and the wooden floor is not suitable for installation on floor heating, so many people decorate the floor in the living room and purchase floor tiles for paving. Thermal expansion and contraction lead to bulging, when we carry out tile paving construction, because the gap between the tiles we reserve is too small, after we carry out heating, because the ground is relatively dry, it is easy to bulge. The thickness of the tile sand and ash layer must be moderate, the floor heating itself is a heating element, after opening and closing, it will cause a greater temperature difference, which directly aggravates the thermal expansion and contraction, if the sand and ash layer is paved too thin, it will also cause a hollow drum warping.

Not splashing enough water under the floor to get soaked before laying the tiles can also cause the tiles to arch. The third reason is the problem of tiling during construction. We know that when paving floor tiles, it is necessary to do it with the grout and plastering, and some workers can't do it.

Ways to prevent floor tiles from drumming: 1. Leave expansion joints between bricks and bricks, the general standard is that the market has to buy tile clips. Just use it when laying bricks!

According to the regional environment of each place to choose the appropriate density of floor heating pipes, do not change the spacing of floor heating because of personal preferences, the distance between floor heating pipes is 15 cm by the window, and 20 cm by the indoor position is the best spacing. The vibration of the ground being knocked is strong, which is a symptom of the lack of pipe clips. This is especially true when floors are paved.

It is recommended that the subject and everyone should open half of the floor tiles to adapt to the temperature change when heating the floor heating in winter, and then turn on the floor heating fully after 3 days. In addition, just turn off the floor heating in spring, try not to mop the floor with a cold water mop, and then mop it with warm water after two days. The tiles are not well laid for the following reasons:

1.Less cement is used, or fake cement is used. Resulting in insufficient adhesion.

2. The back of the tile is not cleaned, resulting in the cement surface and sand surface of the tile not being bonded well.
