One of the most common complaints of old-house owners that make home lovers troubling is kitchen floor collapse. It is almost a problem that happens to many houses, especially the destruction from unhealthy kitchen extensions. The kitchen began to crack and tilt until it seemed to be destroyed entirely. Today, HomeGuru will take you to answer how to fix the sagging floor and repair the floor so that it doesn’t come back to have problems in the future.

The causes of kitchen floor collapse

The floor collapse problem is caused by different reasons. Especially the cause of the foundations and piles that can not support the weight enough when it subsides, it can be observed that the slop was clearly separated from the house. Which HomeGuru would like to summarize the main causes of such problems for 5 reasons:

1. A pile foundation problem

It is the leading cause of such problems, especially piles with insufficient amounts, sizes, and depth to support the weight of the whole structure. As a result, the ground began to collapse rapidly.

In some cases, it may be caused by damaged, cracked, broken piles, or the pile ends are in different soil layers. Make them have different depths. If the piles are not in line with the house pillars, it can cause the lower base to turn over and lead to floor collapse as well.

2. Extension by using old structure of the house

Another cause of sloping or sloping floors is the extension of some structures based on the original house. Whether it is a ground beam surface that receives the floor and the wall. Or even the foundations that are nested on top of the original foundations. Especially if it is not added by separating the structure with foam sheets to integrate the concrete floor, it can cause subsidence.

3. Place heavy objects on the sloping or tilted floor

Placing heavy objects, especially kitchen counters or pantries on the side that is close to the fence, can sometimes cause the structure to be unable to support the weight due to lack of balance.

4. Soil condition

Another reason that the kitchen extensions can easily collapse is that sometimes it is caused by the soil condition. Including piles and foundations that do not fit properly affects unequal loads’ performance, such as soil subsidence and soil movement.

5. Environment and Stimulus

Another reason that should not be overlooked is the subsidence caused by the stimulating environment. Either it is flooded or structures that have been submerged in water for a long time cause their deterioration faster than usual. The nature of the subsidence is from the level of the structural floor to the same plane subsidence. It should be considered the level of subsidence of the floor to find the correct way to repair the floor.


Technique for inspect when the floor is sloping

Although the collapse of the kitchen has already occurred. It is essential to know what the floor collapse is and what it looks like in order to find the right way to deal with it.

• Sloping floor in the new extension
• Seeing a crack in a wall
• The house beam and the wall are clearly separated from each other
• Sagging floor and the corridor has a split. Or, if laying tiles, you will notice that there are cracks
• You can see uneven floor obviously
• Soil subsidence or soil cavities near the house


How to fix and extend a new kitchen to not have problems again

When there is a kitchen floor collapse problem, home lovers worry about not knowing how to fix sagging floor. If you want to renovate your house, what should you do to avoid repeating the problem? By fixing with the extension of the kitchen will be divided into two main parts:

1. Extend the new space as an entirely separate building

In the event of subsidence from the construction that the addition is clearly separated from the house. Especially the construction of walls or laying tiles to connect to the house. You will notice cracks forming at the joints. The fix should not be laying tiles or laying tiles over it because it will cause more damages than before.

The immediate solution is to fix the cracks in the floor and walls by chiseling along the cracks to make a groove about 1 cm deep, 1 cm wide, and then grout with an elastic material such as PU or silicone to prevent water and insects. But if there is a crack in the roof area, it is recommended that stainless steel or galvanized steel sheets be inserted into the grout groove as well.

2. Subsidence from floor and roof structures connected to the house

If it’s a structural problem, repairing the floor will be more complicated. Because there are many factors related to subsidence by the following solutions.

2.1. Slightly subsided soil

For repairing areas caused by soil subsidence, cracks can only be observed to increase at first. But over time, there will be less cracking rate because generally, the soil will settle until it reaches a firm level. The solution is to repair the cracks with a flexible filling material such as PU and not be filled with mortar.

2.2. More subsidence than usual

Of course, suppose the subsidence rate is more significant than usual. The soil has subsided quite a lot. In that case, it is noticeable that the cracks are vast, the floor is tilted and clearly slanted away from the building line, making it unusable. It was noticed that the subsidence of the ground stopped or lessened from the original. You can fix it by dismantling the surrounding walls and change the material to be lighter, such as a Steel frame lined with artificial wood. To reduce the risk of sloping or collapse in the future, then re-level the floor.

Another solution to the kitchen floor collapse problem is to strengthen it with Micro Pile, steel pipe piles, or small concrete piles to support the weight of the kitchen structure. But this method cannot be done by yourself; you should have an engineer or a specialized company to do it instead. However, the cost should be compared first to see if this method is worthwhile compared to demolition and rebuilding.


Simple techniques that prevent kitchen floor collapse in the future

Even if some initial problems with the inclined floor are fixed, keep in mind that new additions may cause further floor subsidence in the future. A simple way to prevent this problem is as follows.

• Select the extension and avoid adding on soil filled for less than 1-2 years or areas that are ponds and marshes because the ground is not tight and may collapse again.
• The new and old structures are clearly separated to prevent subsidence or damage to the existing structure.
• Should use new piles that are the same length as the old ones.
• Use lightweight materials to help slow down subsidence, such as light wall systems, lightweight brick countertops, artificial wood siding, steel frame with synthetic wood lining.
• Arrange the weight distribution plan in the kitchen to help create balance and prevent tilting, such as placing the refrigerator counter of similar weight in opposite corners and should not be placed next to the kitchen counter, etc.


The kitchen floor collapse and home floor collapse problems with vary in degree. Difficulty and ease depend on the damage of the problem.
