House Lifting, also known as house raising, house jacking or building jacking is a highly skill involved process of temporarily lifting a building from its foundation using hydraulic screw jacks. This challenging process is needed for relocating the entire building, as it is, to another location and also for renovating the foundation. The later is the most prevailing application of house lifting in Kerala.
When a second storey is needed on an existing building, chances are that the foundation is not strong enough to withstand the additional load. In some other cases, the foundation may be found to be weak after a few years of construction, whereas the rest of the building is still intact. In such scenarios, the building may be temporarily lifted and a new, stronger foundation may be erected, without disturbing the entire construction.
This is a tricky situation where house lifting comes into play, which is a very convenient and cost saving procedure. However, it is a course of action that requires thorough knowledge of structural architecture.
Once the house is thus lifted, a new foundation may be easily constructed beneath it. Even building an entire storey below the existing house is possible with the help of house lifting.
