Subsurface Correction Work | A Method for Low-Cost Repair While Living Using Carbon Fiber Foundation Rehabilitation Technology
Subsidance correction work
No need for formwork or additional pouring! We achieve long-lasting wooden houses at low cost by reinforcing the foundation with carbon fiber sheets while living in them.
This catalog presents a technical proposal that combines a carbon fiber foundation regeneration method, which does not require formwork or demolition work, with high-precision subsidence correction technology. It aims to minimize the living burden and construction costs for homeowners while achieving the long lifespan of wooden houses. For existing foundations that have developed cracks due to aging or subsidence stress, lightweight and ultra-high-strength carbon fiber sheets are firmly bonded using a special epoxy resin. Since there is no concrete addition or extensive excavation, noise and vibration are minimized, allowing homeowners to continue living comfortably in their familiar homes during construction. Furthermore, for foundation areas experiencing localized subsidence, a "partial jack-up method" is applied to accurately correct the level in millimeter increments. By eliminating unnecessary construction areas, the overall construction period and costs are dramatically reduced, providing strength and structural durability that surpasses new builds. This is a cost-effective and rational solution ideal for aftercare maintenance and reinforcement of existing homes for contractors and house manufacturers.

basic information
This reinforcement system uses high-strength carbon fiber sheets (or aramid fiber sheets), primer resin, impregnating adhesive epoxy resin, and surface non-shrink mortar treatment as standard specifications. Since it does not use heavy machinery or concrete formwork at all, it can be completed in a minimal construction space. Additionally, for settlement correction, a constant force hydraulic jack (capacity 50-150 kN) and a high-precision digital level measuring instrument are used to manage elevation adjustments in millimeter increments. The foundation reinforcement layer is very thin, approximately 2-3 mm thick, which keeps the increase in building weight and the impact on construction restrictions to nearly zero compared to foundation underpinning.

Applications/Examples of results
It is suitable for foundation crack repairs and differential settlement correction work while living in the house, as well as for foundation reinforcement in small residential areas. It is adopted for safe repair work in densely populated areas where heavy machinery cannot be brought in, narrow residential streets, and sites with minimal gaps between neighboring houses. Additionally, it is widely used in projects aimed at reducing stress and costs for homeowners, such as consultations from clients wanting to minimize temporary housing costs and moving expenses, seismic retrofitting projects for single-family homes with budget constraints, and foundation reinforcement work just before a renovation that requires a shortened construction period.
