Underwater repair work | Enhancing the value of used houses with carbon fiber foundation regeneration method
Subsidance correction work
Instantly resolve inspection nonconformities and defects! Achieve the longevity of wooden houses and preserve asset value with carbon fiber-based rehabilitation methods and settlement correction.
This catalog is a proposal for a real estate regeneration solution that utilizes carbon fiber foundation restoration methods and high-precision settlement correction technology to achieve the longevity of wooden houses and the recovery of asset value in response to foundation deterioration issues and building tilt pointed out in used housing transactions and construction inspections. For foundation cracks caused by concrete neutralization and settlement stress, we perform pressurized injection of high-viscosity epoxy resin and the application of carbon fiber sheets with ten times the tensile strength of steel, restoring structural rigidity beyond that of new construction without demolition or additional pouring. Furthermore, for building tilt due to uneven ground settlement, we accurately correct the level in millimeter increments using steel pipe pile driving and pressure plate methods, and we densely fill the voids under the floor with mortar. By providing full support for the submission of strength evidence to public agencies and the reattachment of ground guarantees after construction, we eliminate concerns about liability for defects and strongly promote smooth decision-making and maximization of property value in the buying and reselling business and existing housing distribution.

basic information
This is a thin-layer multi-layer molding system using high tensile strength carbon fiber sheets (tensile strength of 3400 N/mm² or more), epoxy-based anchoring primers, high-viscosity impregnating matrix resins, and non-shrink finishing mortars. With a construction thickness of approximately 2 to 3 mm, it increases the cross-section of the foundation and the self-weight without causing any additional load, providing seismic resistance superior to that of new buildings. For settlement correction, a combination of a small hydraulic jack with a capacity of 150 kN, a high-precision laser level, and STK400 steel pipe piles is used to correct and fix the horizontal accuracy of the building to the millimeter level. We have complete documentation for full-scale test evidence from public institutions such as Better Living, as well as forms for re-attaching ground guarantees.

Applications/Examples of results
It is ideal for repairing foundation cracks and building tilt pointed out during the sale and purchase of used homes or building inspections (housing diagnostics), as well as for repair plans associated with the application of defect liability insurance. It is utilized by real estate purchase and resale businesses for reinforcing existing homes before renovation and by owners who want to prove the structural safety of properties scheduled for sale to prevent appraisal reductions and contract cancellations. Additionally, it is widely adopted in the restoration projects of housing manufacturers and contractors who wish to regain the trust of homeowners through seismic retrofitting of old houses and after-sales support, as well as to reattach ground guarantees.
