Settlement correction work | Clarifying local settlement caused by underground buried waste! Pressure plate jack reinforcement
Subsidance correction work
Objectively clarifying local subsidence caused by buried debris hidden in gaps of ground data! Restoring structural safety through pinpoint underground exploration and pressure plate jacking.
Underground debris and buried waste that cannot be captured at representative points during ground surveys can cause irregular localized subsidence over time, significantly impacting the structural safety of buildings, regardless of whether they are new or old. When underground obstacles hidden between standard SWS tests are the cause, rapid subsidence or structural cracks occur in specific areas rather than the entire building tilting, necessitating an investigation based on scientific data rather than intuitive repairs. Geotech visualizes the location and extent of obstacles through hand auger drilling and pinpoint underground exploration, and conducts numerical analysis of distortions in the exterior and interior using high-precision laser level measurements down to the millimeter. For subsidence correction, we employ a jack-up method with pressure plates that can be implemented in narrow spaces, synchronously driving small hydraulic jacks using the building's own weight as a reaction force, allowing for precise leveling without burdening the structure. Additionally, we combine high-density filling of air bubble mortar (air milk) into underground voids with high-adhesion epoxy resin injection into foundation cracks to prevent re-subsidence and establish the overall seismic and structural safety of the building. Geotech's comprehensive subsidence correction service menu supports a safe living environment.

basic information
This is a local precision diagnosis and uneven settlement correction technology aimed at existing single-family homes (wooden, lightweight steel, cloth foundations, slab foundations, etc.). Ground exploration employs hand augers and probing rods for test digging and soil sampling, while high-precision digital laser levels are used for settlement measurement. For settlement correction, pressure plates made of structural carbon steel plates (12 mm thick and at least 500 mm square) are placed along with small hydraulic jacks, and lifting adjustments are made through linked control. High-adhesion epoxy resin injection materials and U-cut reinforcement materials are used for structural repairs of the foundation, and lightweight bubble mortar (air milk) is used for densifying the subfloor ground.

Applications/Examples of results
It is used for repairing uneven settlement and structural cracks in existing houses caused by buried garbage and waste materials, as well as for correcting the distortion of fittings. It is ideal for clarifying the causes of localized settlement that could not be identified through ground surveys and for providing objective proof of structural safety. It helps in the restoration of foundation cracks and floor inclinations pointed out during residential sales or inspections, and in building technical evidence for defect insurance compliance. While responding to the client's request for construction while living in the house, it is suitable for applications that eliminate long-term risks of re-settlement through GeoTech's settlement correction construction menu.
