Submergence correction work | Achieving the longevity of wooden houses through carbon fiber foundation regeneration methods.
Subsidance correction work
Reinforce existing foundations without additional pouring using carbon fiber sheets! Achieve simultaneous settlement correction and foundation regeneration, realizing longer lifespan and high seismic resistance for wooden houses.
This catalog introduces an advanced ground and foundation reinforcement solution that combines settlement repair work with a foundation regeneration method using carbon fiber sheets, achieving the longevity and seismic resistance of wooden houses. For existing foundations that have cracked due to aging and differential settlement, we significantly restore the shear resistance and toughness of the foundation structure by closely applying carbon fiber sheets, which have ten times the tensile strength of steel, along with high-adhesion epoxy resin, without the need for demolition or additional construction. Furthermore, by combining this with high-precision settlement correction using small hydraulic jacks and steel pipe pile insertion, we can correct the building's tilt to a level state within millimeters, ensuring the permanent bearing capacity of the ground. This method accommodates construction while residents are living in the home, without the need for heavy machinery or temporary housing, minimizing the living burden and secondary costs for homeowners while dramatically restoring the structural safety and asset value of the house. It is a reliable technical system that is also ideal for inspection measures and foundation reinforcement during renovations. We will continue to protect a safe and comfortable living environment for the long term.

basic information
This construction method is a multilayer structural foundation reinforcement system composed of high tensile strength carbon fiber sheets, epoxy primers, high-adhesion matrix resins, and non-shrink decorative mortars. Carbon fiber has a tensile strength more than ten times that of steel and demonstrates excellent effects in preventing concrete neutralization and reinforcing steel corrosion. It is compatible with hand tool construction that does not require heavy machinery, and due to the thin layer application of a few millimeters, there is almost no increase in the cross-section of the foundation. Full-scale strength tests have been conducted by public institutions such as the Better Living Tsukuba Architectural Testing Center, and the effectiveness of improving seismic resistance and bending and shear resistance beyond that of new construction has been objectively demonstrated in unreinforced and cracked foundations.

Applications/Examples of results
It is ideal for seismic reinforcement of old wooden houses and unreinforced foundations, as well as for restoring and reinforcing foundation cracks and structural cracks caused by aging. It is used for foundation reinforcement in conjunction with correction work for building tilt due to uneven ground subsidence, for repairing foundation defects pointed out during inspections (housing diagnostics) when buying and selling used houses, and for strengthening the structural base in seismic renovations and large-scale renovations. Additionally, it is widely adopted in restoration plans for single-family homes where heavy machinery access is difficult in narrow sites or near property boundaries, and where homeowners wish to complete construction in a short period with low noise while still residing in the house.
