How to deal with house foundation sinking

House foundation sinking treatment methods are: soil replacement bedding method, extrusion method, drainage consolidation method, replacement method, reinforcement method, cementation method, etc..

1, soil replacement bedding method

Excavate the shallow weak soil, and then sand, dry slag and other materials to re-fill, crushing, in order to improve the bearing capacity of the base layer, to alleviate the subsidence as well as to improve the performance of the land.

2, extrusion method

Through certain technical means, vibration, extrusion of the foundation, to reduce the pore ratio of the land, improve the strength of the land to improve, to alleviate the purpose of foundation subsidence.

3, drainage consolidation method

Through additional load on the foundation, forcing the water in the pore space of the foundation is gradually discharged, so as to reduce the pore space ratio, so that the soft land foundation consolidation deformation, effective stress and shear strength increase, the foundation is more solid.

4, replacement method

The original foundation in the soft soil replacement into sand and gravel and other materials, the formation of composite foundations, so that the strength of the foundation has been improved.

5, reinforcement method

The high strength materials buried in the foundation, in order to improve the bearing capacity of the foundation, slow or stop the foundation sinking. The use of materials such as geosynthetics, reinforcement and so on.

6, cementation method

Cement, cement mortar and other materials mixed into the foundation of part of the soil, the formation of composite foundations, thus improving the foundation bearing capacity, slowing down the amount of subsidence.
