Settlement correction work | Identification of buried debris lurking in the gaps of survey points! Load-bearing plate jack
Subsidance correction work
Identify localized subsidence of buried waste hidden in gaps of survey points! Safely restore to level in densely packed areas with pinpoint underground exploration and pressure plate jacking.
In densely populated areas with closely packed residential buildings or near property boundaries, hidden buried waste or construction debris between representative points of pre-ground surveys can cause significant problems by leading to irregular uneven settlement. In environments where site space is limited, it is often impossible to bring in large improvement machinery, and concerns about noise and vibrations from construction can force sites to abandon necessary measures due to friction with neighbors. GeoTech employs portable hand auger drilling and pinpoint subsurface exploration to accurately visualize the range of foreign objects lurking near boundaries and the settlement gradient as objective data. In the horizontal correction process, a jack-up method using pressure-resistant slabs is applied, allowing construction to be carried out with minimal working space from the property boundary. Using the building's own weight as a reaction force, small hydraulic jacks perform precise lifting in millimeter increments, avoiding encroachment on neighboring properties and unnecessary demolition work. After lifting, high-flow air bubble mortar is injected into the underground voids, and high-viscosity epoxy resin is also used for the foundation structure where unevenness has occurred. Through GeoTech's settlement correction construction menu, we provide reliable construction that takes into account the concerns of neighbors, even in narrow and densely populated areas.

basic information
This is a technology for correcting uneven settlement specifically designed for existing single-family homes (wooden, lightweight steel, cloth foundation, and slab foundation) on narrow lots. For subsurface obstacle detection, small-scale test excavations using a hand auger and probing rods are employed, and the inclination angle is precisely measured with a high-precision digital laser level. In the settlement correction process, structural carbon steel plates (at least 12 mm thick and 500 mm square) or concrete pressure plates are installed, and millimeter-level lifting adjustments are made using small hydraulic jacks and a quiet electric power unit. For foundation reinforcement, high-adhesion epoxy resin injection materials are used, and lightweight bubble mortar (air milk) is densely filled under the floor gaps under pressure.

Applications/Examples of results
It is used for the restoration of localized subsidence in existing homes caused by underground buried waste, as well as for correcting building tilting and foundation cracks near narrow, densely populated areas and property boundaries. It is ideal for cases where large machinery cannot access flagpole lots or narrow sites, and where there is a close distance to neighboring houses, thus preventing potential issues from construction vibrations and noise. It is suitable for minimal-scale restoration that can be carried out while living in the home, completely eliminating the risks of encroachment and the costs of moving or temporary housing. As a solution to overcome construction constraints in densely populated areas, it is widely utilized in GeoTech's specialized proposals for narrow sites within their subsidence correction construction menu.
