Settlement correction work | Identification of localized settlement due to buried debris! Load-bearing slab jacking method

Identify localized subsidence caused by buried waste lurking in the gaps of survey points! Ensure precise horizontal restoration with pinpoint underground exploration and pressure plate jacking.

The debris and buried garbage hidden in the gaps of ground investigation data can cause irregularities in the ground, leading to significant localized subsidence where only parts of a building settle after construction or over time. Even if no abnormalities are detected in the preliminary investigation data, localized softening can result in dangerous distortions or structural cracks in the foundation and exterior walls. At Geotech, we conduct pinpoint underground exploration and situation identification through hand auger drilling to accurately clarify the causes of subsidence and the extent of abnormalities. In the repair process, we apply a pressure plate jack-up method using compact thick steel plates, allowing for precise millimeter-level horizontal lift-ups with small hydraulic jacks, even in confined spaces, using the building's weight as a counterforce. Furthermore, we fill any voids or cracks that occur after lifting with highly fluid air bubble mortar (air milk) and combine this with high-viscosity epoxy resin injection into the uneven foundation structure, achieving improved foundation strength and preventing re-subsidence. With Geotech's extensive subsidence correction construction menu, we provide structural repairs that ensure peace of mind while living in the building.
