Prefabricated House Foundation Materials
In rural self-built houses, the prefabricated foundation materials or methods mainly include prefabricated slab elevated floors, cement slab bedding layers, and pipe piles.
Prefabricated Slab Elevated Floors: The moisture-proof principle of this method is to "exchange space for dryness." Specifically, after the ground beam is poured, the height of the backfill soil is controlled to be 30-50 centimeters above the ground, and the backfill soil is compacted. This creates an elevated space between the ground and the foundation, effectively preventing ground moisture from permeating upwards and keeping the indoor floor dry. This method is suitable for rural self-built houses with high moisture-proof requirements, especially in areas with high groundwater levels or humid climates.
Cement Slab Bedding Layers: Cement slabs are hard and durable, capable of withstanding significant pressure and tension. They also have waterproof and soundproof functions, contributing to the overall stability of the house. When using cement slabs as foundation materials, they need to be cut into appropriate shapes and sizes to meet the specific needs of the foundation. Cement slab bedding layers are suitable for rural self-built houses with high requirements for foundation strength and stability, such as houses that need to bear heavy loads or areas with poor geological conditions.
Pipe Piles: Pipe piles are steel or concrete prefabricated components mainly used in building foundation engineering. Depending on the material, pipe piles can be divided into prestressed concrete pipe piles and steel pipe piles. Among them, prestressed concrete pipe piles include prestressed concrete pipe piles (PC piles), PHC piles (pre-tensioned prestressed high-strength concrete pipe piles), PRC piles (mixed reinforcement prestressed pipe piles), and SC piles (prefabricated high-strength steel pipe concrete piles), etc. Pipe piles have high bearing capacity and good seismic performance, suitable for rural self-built houses with complex geological conditions or those that need to bear heavy loads. By being driven or pressed into the ground, pipe piles can transfer the load of the building to the deep soil, thereby improving the stability of the foundation.
