Settlement correction work | Correction of settlement cracks in the mat foundation using SWS survey and partial jacking.
Subsidance correction work
The SWS survey scientifically clarifies partial settlement and cracks in the fabric foundation! We will safely restore it with partial jack adjustments that do not stop the lifelines and steel pipe pile driving.
This construction method is a subsidence correction solution for single-family homes that have experienced partial sinking of the foundation or structural cracks. It scientifically investigates the causes based on SWS (Screw Weight Penetration) tests and high-precision level measurements, allowing for partial jacking up while maintaining the living infrastructure. By implementing flexible piping measures that do not disrupt lifelines such as city gas and water supply and drainage, we achieve complete construction while residents remain in their homes, without the need for temporary housing or relocation. For cracks in the foundation caused by uneven subsidence, we apply structural repairs such as epoxy resin injection, and during lifting, we use small hydraulic jacks and laser measuring devices to safely and precisely restore levelness to the millimeter. Furthermore, by combining the driving of steel pipe piles into the supporting ground and the installation of pressure-resistant slabs, we fundamentally eliminate the risk of future re-subsidence. We dramatically reduce the financial and mental burden on homeowners while ensuring the safety of their homes and enhancing property value, so you can trust us to handle it with confidence.

basic information
The applicable targets are wooden and lightweight steel frame houses (compatible with cloth foundations and slab foundations). As a preliminary survey, SWS testing (4 to 7 points) and internal and external level measurements will be conducted. A small multi-stage hydraulic jack (capable of 5t to 20t) and a high-precision laser level monitoring system will be used for the correction mechanism. The reinforcement specifications will standardly include STK small-diameter steel pipe pile driving, installation of steel pressure plates, epoxy resin injection, and U-cut seal material treatment. Flexible joint temporary installations for utility line protection and low-noise electric pumps will be adopted, fully accommodating construction while living in the house.

Applications/Examples of results
It is ideal for the restoration of single-family homes that have experienced partial settlement of the foundation, structural cracks, poor opening and closing of fixtures, and floor tilting due to soil consolidation, weak ground, and the impact of neighboring construction. It eliminates the costs of temporary housing and the hassle of moving, allowing homeowners to complete construction while living without interrupting their daily life. It can also be widely used for prompt responses to after-sales maintenance and complaints by contractors and house manufacturers. By simultaneously reinforcing the foundation and preventing further settlement, it effectively contributes to the reattachment of ground guarantees and the longevity of the building.
