Subsurface correction work | Preventing liquefaction in existing homes by pressurized injection of chemical solutions to prevent pipe breakage.
Subsidance correction work
Prevent risks of pipe damage and utility disruption with pressurized liquid injection! The i-LIFT method allows for precise horizontal restoration of existing homes without damaging the foundation.
In response to concerns about ground subsidence, pipeline breakage due to liquefaction during earthquakes, and damage to foundation structures, Geotech proposes a pre-subsidence prevention and subsidence correction plan using the "i-LIFT method" with liquid pressure injection. This method involves the precise injection of quick-setting cement-based grout into the soft sandy layers directly beneath the building, enhancing ground bearing capacity through a three-stage control of support layer formation, foundation reinforcement, and lift-up. By employing non-destructive construction techniques that do not damage the foundation concrete and pipeline-following technology, we can safely achieve accurate horizontal restoration to the millimeter level without interrupting urban gas and water supply infrastructure. Under real-time monitoring with high-precision laser levels, we avoid applying excessive tensile or torsional stress to structural elements and buried pipelines. This solution enables "construction while living," preventing the need for temporary housing or relocation, thereby protecting the residents' comfortable living environment while ensuring peace of mind by preventing future subsidence and infrastructure damage.

basic information
Based on the i-LIFT method (patent-pending technology), we perform ground reinforcement and building lift-up by pressurized injection of quick-setting cement-based grout into the ground. For construction management, we employ high-precision laser levels and pipeline displacement tracking monitoring, implementing real-time control to the millimeter level. This is a non-destructive approach that does not damage the foundation structure and includes standard measures for the preservation of lifeline pipelines. We use compact electric equipment to achieve safe construction with low noise and low vibration.

Applications/Examples of results
It is ideal for the prevention of pre-subsidence in existing homes where there are concerns about the breakage or leakage of water and gas pipes due to ground subsidence, as well as for the horizontal correction of tilted single-family homes caused by uneven subsidence. It can be widely used in residential renovation sites where homeowners want to complete construction without stopping essential infrastructure such as water and gas while living in the home, in sites where they want to reinforce the ground and building as a single unit without damaging the foundation concrete structure, and in applications aimed at preventing piping damage and building damage due to liquefaction during large-scale earthquakes.
