Subsidized Improvement Work | Achieving Liquefaction Prevention and Ground Strengthening for Existing Homes through Liquid Pressure Injection
Prevent liquefaction settlement risks in existing homes with pressure-injected chemical solutions! Dramatically strengthen the ground and protect your home with the i-LIFT method and high-precision laser measurement.
GeoTech proposes the "i-LIFT Method," a pre-subsidence prevention technique using pressure-injected chemical solutions for existing homes facing the risks of liquefaction and uneven settlement during earthquakes. This method is a groundbreaking technology that significantly enhances the ground's bearing capacity through three steps: pressurized injection of a quick-setting cement-based grout into the ground, formation of a support layer, foundation reinforcement, and lifting of the building. By using high-precision laser measuring instruments and 3D measurement devices to continuously monitor displacement in real-time during construction, it allows for precise horizontal correction in millimeter increments without imposing excessive loads on the building structure. The use of compact and small construction machinery means that there is no need for large heavy equipment transportation or house demolition, even on narrow sites. Furthermore, by using environmentally friendly injection materials, it does not contaminate the surrounding environment or groundwater, perfectly achieving "construction while living" without the need for moving or temporary housing. This is a reliable ground reinforcement solution that ensures the structural safety of your important home and completely eliminates the risk of future subsidence.
basic information
Based on the i-LIFT method (patent-pending technology), a quick-setting cement-based grout material is pressure-injected into the ground. The construction consists of three processes: "support injection," "foundation reinforcement injection," and "lift-up injection," with real-time level management using high-precision laser measuring instruments and 3D tilt measuring devices. The grout material used has low environmental impact and is chemically stable, maintaining the ground's bearing capacity over a long period. A compact construction machine is employed, making it applicable even in narrow spaces and on sites that have undergone ground improvement.

Applications/Examples of results
It is ideal for preventing tilting and sinking of existing homes due to ground liquefaction during an earthquake, as well as for horizontal correction of single-family homes that have experienced differential settlement. It is effective in densely populated residential areas where large machinery cannot enter, in sites where ground reinforcement is desired without damaging the foundation structure, and in narrow lots where the distance to neighboring boundaries is close. Additionally, it can be widely used in renovation projects where homeowners wish to remain in their homes during construction without moving to temporary housing, as well as in applications aimed at preventing future settlement and maintaining or restoring the asset value and safety of the home.
