Settlement correction work | Epoxy pressure-resistant slab method to repair foundation cracks and settlement in small sites.
Subsidance correction work
Resolve foundation cracks and partial subsidence near narrow lots and property boundaries! Safe restoration with high-viscosity epoxy resin injection and pressure-resistant slab method, considering neighboring properties.
This is a subsidence correction technology that safely and with low vibration resolves partial subsidence issues accompanied by foundation cracks in densely populated residential areas and narrow sites adjacent to property boundaries. For foundation cracks caused by excavation on neighboring land or lateral flow of fill, high-viscosity epoxy resin is injected densely to strongly bond and reinforce the broken structure, restoring structural rigidity and waterproofing. In the lifting process, it accommodates narrow sites where large machinery cannot enter by concentrating compact, high-strength steel pressure plates directly under the foundation. Using small hydraulic jacks and high-precision laser measuring instruments, the building's weight is used as a reaction force to carefully lift it millimeter by millimeter, returning it to a precise horizontal state without affecting neighboring houses. After correction, self-hardening lightweight bubble mortar (air milk) is poured into the voids under the foundation to densify it, expanding the contact area to prevent re-subsidence. With construction carried out while residents are living in the home, eliminating the need for temporary housing, and thorough low-noise and dust control measures, it minimizes neighborhood disputes while protecting the structural stability and asset value of the home.

basic information
The subject is the local subsidence repair of cloth foundations and slab foundations on narrow sites. For the repair of foundation cracks, high-viscosity epoxy resin injection and U-cut seal treatment are used to quickly restore structural strength. For subsidence correction, a pressure-resistant plate made of steel with a thickness of 12mm or more (such as 500mm x 500mm) and a compact hydraulic jack are employed to lift with millimeter precision. For filling the voids at the bottom, self-hardening lightweight bubble mortar (air milk) is used, which does not exert excessive lateral pressure on surrounding structures, ensuring uniform and solid fixation of the ground and foundation.

Applications/Examples of results
It is ideal for repair work on foundation cracks and localized subsidence that occur in densely populated residential areas where the site is narrow and large machinery cannot enter, as well as in areas adjacent to property boundaries and retaining walls. It is chosen for sites where there is a strong desire to thoroughly prevent vibrations and noise from construction, as well as complaints from neighbors due to road occupation. It is widely utilized for homeowners who want to correct tilting and cracks in a short period without temporary housing or evacuation, as well as for structural reinforcement and ground guarantee reattachment purposes before remodeling small houses.
