Solving the collapse of the house

  1. house collapse problem It can be caused by many reasons, including external factors such as soil subsidence caused by floods, floods. Earthquake or collapse caused by construction factors such as non-standard soil filling non-standard piles non-standard construction There are also other factors that cause the house to collapse. due to applications such as structures carrying more weight than designed As a result, the building collapsed more than expected. House collapse occurs a lot, especially in the central region. because there is a soft soil layer foundation design and insufficient piles As a result, more houses collapse every year.


What happens when the house collapses?

We separate the issue of subsidence into 2 types: subsidence of the soil around the house. and the collapse of the structure We will talk about it separately. to be used to solve the problem of subsidence of the house depending on the reason to be corrected


subsidence caused by the soil around the house

Soil subsidence around the house no damage to the structure of the house It's just the difference between the soil level around the house and the house. There will be a hollow around the house which sometimes allows different animals to live and affects the beauty of the residents' homes. The soil around the house that collapsed was caused by land reclamation. that does not wait for the soil to set before hurriedly constructing Therefore, from general housing estates, soil subsidence can be seen from the first year of use. and will increase with use


How to fix soil subsidence around the house

How to fix the soil that has collapsed around the house can be solved by adding more soil. and be able to use water cement (flowable cement slurry) compressed into the floor to increase the distance This is to fill the gap under the house to be the same distance as the additional soil. This correction will help to fill the gap between the gap and the soil. do not allow animals to live And there is another method for preventing soil from slipping under the structure of the house by making a wall. Around the home base by this method, there will be more steps. But it can provide long-term protection against subsidence of the home.


Fixing a house collapse caused by the structure

Fixing a collapsed house in this way is necessary to check for subsidence. by checking the slope subsidence of the house and examined by the subsidence rate by using engineering principles to check, such as broken piles or equal subsidence due to soft soil and the stake sits on soft soil. Correction can be done by reinforcing piles. (Underpinning) When reinforcing piles, it is necessary to modify the foundation. to support new piles

Cause of the hollow under the house

Residential houses are generally built in a hurry to reduce financial costs and can speed up sales. When the project owner has the land ready for construction, he will quickly fill and build without compaction and soil subsidence testing to see what it looks like. When constructing the house, it sits on piles, which has a very low rate of subsidence. But when looking at the ground around the house, the soil is filled to the level of the house. When these soils are used for general age. was a natural deterioration. Compared to the level of buildings or houses without subsidence, there will be cavities under the house or around the house. 


Is the hollow under the house dangerous?

Structurally speaking, there is no danger, but in reality, the burrows under the house are hidden by other dangers, such as being inhabited by venomous animals such as snakes and centipedes, where mud and dirt can accumulate. This is where water accumulates, which will result in long-term structural damage. The burrows under the house also make it an unsightly place for homeowners and families with small children need to be wary of poisonous animals. It is necessary to take into account the repair of the niche under the house. In the case of subsidence of the soil around the house until there is a large difference in level will have a huge impact such as The car cannot be parked due to the high slope of the garage floor. Filling the soil only for one's own home cannot be solved. have to fill the whole project, which is a huge expense

Temporarily closing the niche under the house

Temporary closure of the cavity is the closure of the cavity without any modifications or additions. Just to make your eyes comfortable Most of them must be a little subsidence. From the beam level to the original soil, not more than 10-15 centimeters, by means of correction, can use plant pots to block around or remove bricks to arrange open surroundings. If the burrow is not much subsidence, you can use sand mixed with crushed stone to ask in a hilly way. But this cannot be solved in the long run. This may need to be revised every 6 months.

Fixed cavity closure correction (20 cm max)

If you want to fix it permanently, there will be no more openings. We can fix it using a simple but long-lasting method. We will use a smart board or viva board with a thickness of at least 12 millimeters to be attached to the walls around the house. The soil should be digged at least 15 centimeters lower than the original. After that, pour a mortar and sand as an embankment to prevent shifting or subsidence around the house. Before covering the soil and finishing it.


Fixed closed cavity correction (20-50 cm).

To fix a cavity with a depth greater than 20-50 cm, we have a few different solutions. We recommend using precast concrete slab material to be fenced off by using chemical anchors or epoxy to anchor the structure before sand and soil are filled respectively. This fix can prevent cavities for at least 5-10 years, after which the depth of the niche under the house should be rechecked to see how deep it is. Suitable for editing in the next step 

Fixing this cavity requires the use of quality materials for installation. And should use skilled technicians to close the niche around the house, so we can answer your questions. by systematic editing at a fair price 

The correction steps are as follows: .

  1. Do a survey around the house to see what kind of subsidence looks like. What is the difference between soil depth and house level? Explore the surrounding land and obstacles such as extensions, pipe systems, water tanks, plant pots, walkways, etc. 

  2. make a rough design In order to calculate the amount of material needed, such as cement, sand, cover material, chemical plug or epoxy plugged steel.

  3. Make bids for customers

  4. Initiate installation and repair

Filling material that when closing the niche under the house

When the niche under the house has been closed We have to fill the place, which is quite expensive. Because the more the house has a lot of space, it must use a large amount of filling material. Some after the soil has subsided a lot and the large area is 100+ cubic meters. The most popular material used for filling is sand. because it is easy to buy can be brought into the filling with the force of people And most importantly, it can be added to a future structure. Sand filling also takes into account the loading of materials into the work site or village. Because the vehicle that enters the village is only a 6-wheeled vehicle, which can carry only 5 cubic meters, causing the cost of transporting sand filled with high volumes. Sometimes it takes more than 20 trips to complete.


After the sand has been filled, we can choose to cover the surface or pour concrete accordingly. which we would recommend if you want to make a structure or pour the floor It should be thought before not filling in order to prepare the substructure or underground supporting structure before the superstructure or superstructur, for example, if you want to build a 1-storey kitchen, you will be able to prepare piles or sewage system drainage before filling. which if 4 m, then need to dig up and do it again Waste of time and labor 

type of filling material

General reclamation soil is the soil that is the second layer next to the topsoil. which often resemble clay Flexible when exposed to water and small particles Which is suitable for jobs that use loaders and machines for grading and compacting, can't use manual labor This type of soil is suitable for filling large areas to achieve a level. It will be transported as a 10 wheel trailer.


The topsoil is the soil that is the top layer. Fine, soft and crumbly. It can be used for planting trees and covering the top of the soil. It has a high price and is mainly used for decoration. It is not commonly used for filling the place due to its high price.


Lateral soil is a soil that has a mixture of gravel or small stones mixed with red color with high density. Contains soil in the ratio of 30%, used for road filling work, road filling work because it has higher load-bearing strength than other types of soil. The soil is not suitable for planting trees.


Sand reclamation or duck manure It is a sand that is commonly used to fill small villages. able to use human labor Filled sand will penetrate and flow into holes, holes or cavities well. Easy to work with by manual labor. Moderately priced  


Fixing the soil around the house is a very budgetary task as it uses a large amount of material. It's also important to prepare your budget and when to start. But it should always be borne in mind that the subsidence of sand or soil is natural and is subject to subsidence over time. To fix it, we should check every 5 years that the area or house we live in is usable and beautiful. live or not If found to be inoperable due to further subsidence Afraid that animals will come to harm It should be modified to be fully usable. The house should work perfectly.
