The floor heating in the home has been installed for 5 years, why do some tiles bulge?

Causes of bulging tiles:

1. Thermal expansion and contraction lead to drumming: when we carry out tile paving construction, because the gap between the tiles is too small, after we carry out heating, it is easy to bulge because the ground is relatively dry.

2. The ratio of materials is unreasonable: when we are constructing, the ratio of sand and cement does not meet the reasonable requirements, which will also lead to poor adhesion between the tile and the ground.

3. Improper construction methods: If our original ground is relatively smooth, we do not carry out brushing treatment on the ground when we carry out tile construction, etc., which is easy to lead to the phenomenon of arching and bulging of tiles.

4. No good maintenance: when we pave the ground tiles, the newly paved tiles and concrete are not fully dry, if we step on them, this will also lead to the situation that the tiles and the ground are not firmly bonded, and there will be arching after a long time.

How to prevent floor tiles from bulging?

1. Reserved expansion joints: When we carry out tile construction, expansion joints must be reserved between tiles, generally left and right, and for the places where we buy tiles now, there are actually special clips, and we can use them directly when laying bricks.

2. Buy high-quality materials: for the building materials we use, we had better buy brand manufacturers, and the cement number used should not be too high, it is recommended to use 325 models in summer, and if the indoor temperature is low in winter, we can choose to use 425 according to the actual situation, so that it will not lead to the cement solidification too fast and avoid hollowing.

3. The material ratio and use should be reasonable: for the sand we use, especially when paving the floor tiles, it is not appropriate to use too fine sand, which will lead to too high water absorption, can not retain the water, resulting in the situation of hollowing the tiles, paving floor tiles generally we choose the dry paving method, the ratio of sand and cement is generally 1:4, the proportion is too large or too small will appear hollow.

4. Buy high-quality floor tiles: two kinds of tiles produced with different materials will be heated and expanded differently, and there will also be warping.

Because at that time, there were no seams when laying tiles, and then due to thermal expansion and contraction, these tiles would bulge when exposed to heat.

1.The most common reason is that the gap between the tiles is too small during the construction site, and the heat cannot evaporate, causing the tiles to bulge. 2.When tiling is done, there is no brushing treatment 3The tile does not fit firmly with the ground, and the adhesion is not strong.

The reason for the tile bulging up may be 1 thermal expansion and cold contraction leading to drumming, when we lay the tile, the gap between the tiles is too small, after we carry out heating, because the ground is relatively dry, it is easy to drum, 2 when we are constructing, the proportion of sand and cement does not meet the appropriate requirements, resulting in poor adhesion between the tile and the ground, 3 when the floor tile is pasted, there is no brushing treatment on the ground, and it is easy to cause the tile to bulge and so on.

1. Thermal expansion and contraction lead to drumming: when we carry out tile paving construction, because the gap between the tiles is too small, after we carry out heating, it is easy to bulge because the ground is relatively dry.

2. When we are constructing, the 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 the cement grade is relatively low, the sand is more, and the cement of the lower layer will not be able to bond the floor tiles for a long time.

The reason why some tiles will bulge up is because the quality is not too hard, and then due to the thermal expansion and contraction of floor heating, the gap between the tiles is small, resulting in the tiles bulging.

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, 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 bulging, 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 heatedThe 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 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.

If our original ground is relatively smooth, when we carry out tile construction, the ground is not brushed, etc., it is easy to cause the tile to arch and bulge. Tile it has thermal expansion and cold contraction, so it must be used when paving tiles during constructionPay attention to seam constructionThe gap does not need to be too big, just leave more than 1mm, which is the biggest reason for the hollow drum of tiles. When laying floor tiles, the cement and yellow sand were not mixed in the correct proportion.

If the cement grade is low and the yellow sand is put too much, after a long time, the cement in the lower layer will not be able to bond the floor tiles, causing the floor tiles to be upturned.

When making coils, the pipes are more concentrated, and the heat will be too large, resulting in a higher temperature at this position, which will make the ground withstand a higher temperature, resulting in cracking and bulging of floor tiles. Not splashing enough water under the floor to get soaked before laying the tiles can also cause the tiles to arch. Now the decoration is paved with floor tiles, with very little cement mortar, the purchase of other materials for paving, the floor heating above the paving tiles appear bulging, most of the paving does not leave the corresponding expansion joints.

Now it is all dry paving process, most likely because the sand surface is uneven, resulting in no complete contact between the cement surface of the tile and the sand floor, resulting in the hollowing of the tile in the later stage.

Another reason why the tiles bulge up on the floor is that we haven't taken care of the base layer properly. The grassroots layer mentioned here is not handled well, that is, when we pave the floor tiles, the bottom layer is not cleaned. To reduce the occurrence of this situation, you can make a layer of ground solidification on the ground after the floor heating backfill, do not use expired cement for cement, the sand must be river sand, and you can also use some special powder for ceramic tiles to reserve expansion joints.

The renovation workers did not carry out the dehairing operation on the original cement floor; When laying tiles, there is no hard knocking, which is a tight fit between the tiles, and it is easy to cause the tiles to warp without using tile clips. 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.

Because of the principle of thermal expansion and cold contraction, underfloor heating will cause the temperature on the floor to be too high, and the gap between the tiles is too small, which will cause the tiles to bulge.

Because of thermal expansion and contraction, when using floor heating, the tile begins to expand when heated, but the surrounding space is too small, it can't expand, it can only bulge. When laying tiles, a reasonable space should be reserved for the thermal expansion and contraction of the tiles.

Because this floor heating is in the process of installation, the middle of the tile is not inlaid well, so it forms a gas, and this situation forms the phenomenon of bulging, which is also very terrible.

Because of thermal expansion and contraction, floor heating is to provide heat, because when the tiles are paved, there are gaps between the tiles, which will make the ground after heating dry and bulge.

It is because the temperature is relatively high when the floor heating is turned on, and the tiles will expand thermally when heated, and they will naturally bulge, so it is best not to lay bricks on the ground for houses with floor heating.

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.
