Submergence correction work | Strongly supporting the longevity of wooden houses with carbon fiber foundation regeneration method.
Subsidance correction work
No need for demolition, perfect for renovation sites! Proposing a method for extending the lifespan of wooden houses and improving construction efficiency through carbon fiber foundation regeneration and subsidence correction work.
This catalog proposes the "Carbon Fiber Foundation Restoration Method" and ground subsidence correction solutions, which demonstrate significant effectiveness during large-scale renovations and seismic retrofitting of existing homes, aimed at contractors, house manufacturers, and renovation businesses. By closely applying carbon fiber sheets, which have ten times the tensile strength of steel, to the existing foundation structure while concurrently conducting seismic retrofitting of the superstructure, we can significantly restore and enhance the bending strength and shear resistance of the foundation without the need for demolition or additional construction. Additionally, for issues such as uneven subsidence of the ground or tilting of the house discovered during on-site surveys, we combine high-precision subsidence correction work using small hydraulic jacks and steel pipe pile driving to accurately level the structure to the millimeter and prevent re-subsidence. Our compact construction system, which does not require heavy machinery, allows for smooth completion even in narrow sites or occupied locations, minimizing the occurrence of additional construction periods and cost increases. With reliable technical evidence and ground warranty support, we strongly assist in gaining the trust of clients and improving order rates.
Inquire About This Product
basic information
This is a thin-layer multi-layer molding system using high tensile strength carbon fiber sheets, special epoxy primers, matrix-impregnated resins, and non-shrink finishing mortars. It is designed for complete hand tool construction without the need for heavy machinery, providing reinforcement effects equivalent to or greater than that of foundation underpinning with a construction thickness of only about 2 to 3 mm. For settlement correction, a combination of small hydraulic jacks with a capacity of 50 to 150 kN, high-precision laser levels, and STK steel pipe piles (with an outer diameter of 114.3 mm, etc.) is used to implement underpinning methods and pressure slab methods that use building loads as reaction forces. It is equipped with strength evidence documents and standard construction procedure manuals from public institutions.

Applications/Examples of results
It is suitable for large-scale renovations of detached houses, seismic retrofitting work, and reinforcement of existing foundations and restoration of differential settlement associated with renovation plans. It is utilized for ensuring the structural integrity of the foundation before renovations in the used housing purchase and resale business, and for rapid response to foundation cracks and building tilt complaints related to after-sales maintenance by construction companies and house manufacturers. Furthermore, it is widely adopted for reinforcing foundation strength associated with extensions and renovations, construction in sites where it is difficult to bring in large machinery due to narrow lots or proximity to property boundaries, and for foundation repair work that considers the homeowners living on-site, featuring short construction periods, low noise, and low vibration.
