Underpinning repair work | Epoxy injection method for foundation cracks that can be repaired while living in the house.
Subsidance correction work
No need to move, and temporary housing costs are zero! We will repair foundation subsidence and cracks while you live there using high-adhesion epoxy resin injection and pressure-resistant slab methods.
This is a reliable home repair solution that allows you to safely and neatly repair building subsidence with foundation cracks while living in your familiar home. Since there is no need for moving or securing temporary housing, you can significantly cut unnecessary secondary costs and efforts, which can range from several hundred thousand to several million yen. High-viscosity epoxy resin is injected densely into the damaged foundation structure due to subsidence stress, firmly bonding and reinforcing the cracks to improve structural strength and waterproofing. In the lifting process, a compact pressure plate and hydraulic jacks are set under the foundation, and the building's behavior is monitored with high-precision laser measurements to accurately correct the tilt in millimeter increments. By using quiet equipment that minimizes noise and vibration, and thoroughly implementing dust prevention measures to keep dust from entering the interior, the construction can be completed in a short period without compromising the comfort of remote work or daily life. After the jacking up, air milk is filled at the base to prevent re-subsidence, and we provide consistent support until the ground warranty is reattached, delivering the highest sense of security to the homeowner, even better than at the time of new construction.

basic information
We will primarily use quiet and dust-proof equipment that takes into consideration the residents. For foundation repairs, we will combine low-pressure, high-viscosity epoxy resin for dense injection with carbon fiber reinforcement sheets to improve the toughness of the structure. For lifting, we will use pressure plates made of high-strength steel plates with a thickness of 12mm or more, along with hydraulic jacks controlled by an electric hydraulic power unit, to lift while minimizing noise and vibration. We will inject self-hardening lightweight air mortar into the gaps under the foundation with high density to evenly level and securely fix the ground contact surface.

Applications/Examples of results
It is ideal for restoration work on single-family homes that want to resolve foundation cracks and partial subsidence without leaving the familiar home. It is chosen in environments where families work from home, and where small children and elderly people live together, as it helps reduce the stress of living during construction and secondary costs. Additionally, it is widely used for aftercare maintenance of older single-family homes, structural reinforcement before renovation work, and for the long-term preservation of homes through the reattachment of ground guarantees.
