Settlement Correction Work | Liquid Pressure Injection Horizontal Restoration Method to Prevent Resettlement of Improved Ground Houses
Subsidance correction work
Dramatically improve the risk of re-sinking and liquefaction sinking in improved foundation homes! Restore a solid foundation and perfect level using the i-LIFT method with pressure-injected chemical solutions.
GeoTech offers a settlement correction plan using the innovative pressure-injection method "i-LIFT Method" for sites where ground improvement work has been carried out in the past and for existing homes under complex geological conditions facing uneven settlement and liquefaction issues. This method can be implemented regardless of the type of existing reinforcement or foundation, successfully achieving everything from the formation of support layers to foundation reinforcement and the lifting of buildings by injecting a quick-setting cement-based grout into the soft layers within the ground. With real-time continuous monitoring using high-precision laser levels and three-dimensional displacement measuring devices, precise adjustments can be made to the millimeter level, restoring the structure to a healthy horizontal state without imposing any burden on the residential framework. The environmentally friendly injection material has low dispersion and long-term chemical stability, thoroughly preventing re-settlement and liquefaction after construction. This efficient approach does not require large-scale excavation, demolition, or temporary relocation for homeowners, thereby permanently enhancing the value and safety of residential assets.
Inquire About This Product
basic information
This is a ground pressure injection settlement correction technology using the i-LIFT method (Patent Application No. 2003-430063). The injection material used is a non-dispersive, chemically stable quick-setting cement-based grout, which maintains the ground's bearing capacity for an extended period. A high-precision laser measuring device and a computer-controlled three-dimensional tilt measurement system are employed as a control system, allowing for continuous real-time measurement and management of displacements before, during, and after construction. The compact equipment layout makes it possible to carry out construction even on improved ground sites or in narrow areas.

Applications/Examples of results
It is ideal for correcting the sinking of existing houses that have experienced uneven settlement due to the boundary between cut and fill, as well as resettlement after ground improvement work, and for preventing liquefaction settlement during earthquakes. It can be utilized to precisely lift the entire building or sloped areas, regardless of specific foundation structures such as slab foundations or strip foundations. It is widely suitable for home renovations that want to implement "construction while living" without temporary housing, for densely populated areas or narrow sites where large machinery cannot be brought in, and for single-family homes that want to ensure long-term structural safety and completely eliminate future resettlement risks.
