Subsurface Improvement Work | Blocking Liquefaction Risk of Existing Homes with Liquid Pressure Injection in Limited Spaces

Prevent liquefaction settlement risks in narrow and densely populated areas with chemical grouting injection! Safely restore existing homes to a level position using the i-LIFT method and digital measurement.

GeoTech offers a pre-subsidence prevention and subsidence correction solution using the "i-LIFT method," which employs liquid pressure injection technology for existing homes located in narrow sites or densely populated residential areas where large machinery cannot be brought in. This method utilizes specialized equipment that is ultra-compact and easy to transport, allowing for the precise injection of quick-setting cement-based grout into the soft sandy layers directly beneath the building. This technology gradually achieves the formation of a support layer, foundation reinforcement, and millimeter-level lift-up. By utilizing high-precision digital 3D displacement sensors and laser levels, we continuously visualize and monitor the behavior of the building in real-time during construction, ensuring that the correction is made to a perfect horizontal state without placing excessive stress on adjacent houses or structures. The method eliminates the need for large-scale demolition or excavation, allowing homeowners to remain in their familiar residences while construction is completed, accommodating "construction while living." With a focus on low noise, low vibration, and space-saving construction practices, we enhance the seismic resistance and structural safety of homes while preventing neighborhood disputes.

basic information

Based on the i-LIFT method (patent-pending technology) that accommodates construction in narrow and densely populated areas, we use compact small electric equipment to pressurize and inject a quick-setting cement-based grout material. By implementing staged injection (support injection, foundation reinforcement injection, lift-up injection), we enhance the ground bearing capacity and safely lift the building. Using a digital 3D inclination measurement device and a high-precision laser level, we precisely control the lift displacement in millimeter increments in real-time. The equipment setup is extremely space-efficient, making it applicable even in sites with narrow access routes.

Applications/Examples of results

It is ideal for liquefaction settlement prevention and horizontal correction work for existing houses in densely populated residential areas where large construction vehicles and excavation machinery cannot enter, and where the distance from neighboring property boundaries is extremely narrow. It demonstrates its effectiveness in renovation sites where there is a desire to dramatically improve the ground support capacity under the foundation without demolition or site expansion. Additionally, it is widely used in single-family homes where there is a need to avoid temporary relocation of residents and complete construction in a short period while maintaining living infrastructure, as well as in applications where future differential settlement and re-settlement need to be reliably prevented.
