Preventing burrows that have the potential to occur after building a house Homeowners may prepare from the land reclamation process. Or laying piles before building a house by these 2 methods, there are different things to know.
1. Filling the soil before building Prevent burrows under the house
It is important to adjust the area. Taking into account the following factors:
1.1 Characteristics of the area to be filled with soil
Should check the nature of the preliminary area. For determining the height of the soil to be filled
1.2 The height of the area to be filled
1.3 Period of leaving the space
Considerations for land reclamation
For a house built from the same area that may be demolished to build a new one When additional fillings may be used, rubble bricks and concrete scraps from the old back may be used to fill the land. Which in this case will cause more soil subsidence problems than usual Because those scraps will not mix with the soil. There is a gap And over time, if water seeps through, the soil will flow down instead of the gap. Causing subsidence into a hole or a cavity under the house
Land reclamation if you can choose the time period should be carried out during the rainy season Because rainwater that flows between the soil will help the soil to collapse and tighten.
2. Laying the foundation of the structure from scratch
Preventing soil subsidence until a hollow under the house is formed. The best way is to have piles to support the weight. In general, the house structure is defined as having long piles that go down to the subsoil layer or the average sand layer about 18 - 21 meters, depending on the analysis of the engineering properties of the soil layer. Which will be brought Calculate and design the load carrying capacity of the soil layer as accurately as possible according to engineering principles. To support the weight of the house
