Have you ever encountered a problem with your home like this? The soil collapsed, saw a hollow under the house There are cracks around the house. The floor around the house or the parking area collapsed, separated from the house. This is a warning sign that your house is suffering from subsidence. And is the collapsing house dangerous for the residents? How to fix it? Today let's look at the reasons that cause the housing collapse, the house is hollow, the soil collapses around the house, and how to fix it before the house is damaged.

1.The problem of the house collapsed

Thailand has a soil subsidence rate occurring every year. This was caused by several reasons such as the softness, hardness, and density of the soil texture in each area where the collapse was different according to the soil structure and composition. Such as the soil in Bangkok They are clay silt, the estuary makes them soft and easy to settle, and suburban homes are often located on land that was previously bogged down and sold for filling. This makes the newly filled soil more easily settling than natural soil or building a village on an area that used to be a fishpond could also cause the hometown to collapse.

In addition to the structure of the house, if the house is added, such as the kitchen, the garage, or the overweight items are stored in the house, it is one of the reasons that the house collapses. Including non-standard construction, such as not checking the soil well before laying the piles, causing the foundation of the house to be weak, which makes the house more inclined to collapse. Or drilling using groundwater in different areas Which can also cause problems of soil subsidence

How to spot the signs of a collapsed house

• There are large cracks on the house wall or pole. Or there are long cracks around the house or there are cracks in the characteristics of the houses collapsing unevenly until the walls separate diagonally.
  
  
• The ground collapses until the hollow under the house or the soil subsides and flows into the basement of the house or the soil under the house collapses until the pillar and beams emerge, forming a hollow under the house basement. But how much will affect the house depends on the stability of the pile. In addition, soil that sag, if left unattended, can become a habitat for snakes or rats.
  
  
• The beam and wall structure are clearly separated.
  
  
• The floor around the house or the floor of the extension or collapsed floor separate from the house.
  
  
• The walls of the house or floor are noticeably tilted.
  
  
• Pipe or system work under the house space is separated from each other.

How to solve the problem of a collapsed house

• Contact a specialist or consult a construction engineer to find the cause and the right solution. Do not use general builders because if the problem is from the structure of the house, solving the problem only for what can be seen. For example, there are cracks in the wall, but corrected with cracking to cover the cracks, it will fix the problem that is not at the point. The correction to the structure may have to dig the ground to repair the foundation or use the dotted pole to support the house on the sloping side There are several methods for repairing a broken house depending on the nature and severity of the problem encountered.
  
  
• If the foundation is damaged beyond repair or the ground is very subsidence. The house strumming method should be used to help solve the problem of a collapsed house without breaking the house. How to pull the house off by cutting the house out of the original foundation and lifting it up until it floats to dismantle the foundation and build a new foundation before joining the house to the foundation. But the house flip is very expensive and difficult. Therefore, must be operated by specialists
  
  
• Polyurethane spraying to level the substrate. Without having to hit the ground. Polyurethane injection makes it possible to support the weight. Strengthen the soil layer and increase the load-bearing capacity of the soil under the original structure Able to support the weight of up to 20 tons per square meter. And can lift loads of up to 50 tons per square meter. The polyurethane will penetrate through the gap of the soil layer, combining with the sandy soil as the substance continues to expand, it will lift the subsidence. Causing the settling area or a different level area to be lifted as much as the original or as required

2.Soil problems around the house collapsed.

This problem is not as troubling as a collapsed house. The cause is usually from the landfill and adjusts the area without allowing time for the newly filled soil to set up tightly first. Then hurriedly the construction too soon, after building the house for a period of 1-2 years. In heavy rains, the soil collapses and flows downward into a cavity under the house, or the soil flows along the water to neighboring areas. In addition, the subsidence of the soil in some cases. It May be caused by natural changes in soil layers in that area

How to solve the problem of soil around the house subsidence

• By adding soil or sand to fill and spray water until the soil is firm to a certain extent and build a retaining wall. The basement of the house by using prefabricated slabs to plug around the house as deep as possible until it can be attached to the beams or columns of the house in order to prevent the newly filled soil from flowing under the house basement. Or build a retaining wall along the wall around the house to keep the soil from flowing out and use ready-made slabs to plug around the wall of the house by plugging it as deep as possible and attaching it to the foundation of the wall firmly. This will solve the problem in the long run.

If there is a collapse of the housing problem, do not be silent. Should consult a professional engineer to find the right solution and repair it as soon as possible before the problem escalates to the maximum solution. Because repairs at the right spot will reduce the damage to the house structure and save more money than dismantling the whole new home foundation.
