In the Great Hanshin-Awaji Earthquake, localized loosening occurred in the foundation of office buildings due to liquefaction and intense vibrations over a wide area of the coastal region, and we restored the areas that had sunk. We entered the underground pit (900mm) from the opening on the first basement floor and drilled holes. Additionally, since the groundwater level is at GL-1.0m, we installed injection pipes while performing water stop injections for the pressurized water. Due to the irregular shape of the building, we measured the uplift both externally and internally to confirm any bulging, and we applied JOG to prevent distortion. 【Case Overview】 ■ Location: 2-chome, Sakaemachi, Chuo Ward, Kobe City ■ Building Name: Office Building ■ Structure and Scale: RC structure, 1 basement floor, 6 above-ground floors ■ Foundation Structure: Slab foundation ■ Total Restoration Weight: Approximately 3,500t *For more details, please refer to the PDF document or feel free to contact us.

The RC pool has a length of 25m and a depth of 2m to 4m, with uneven loading. It is believed to have settled due to water leakage from the circulation piping. Additionally, the ground around the leakage area has loosened, causing the southeast corner to settle locally and deform. The plan was to perform overall support strength enhancement injection to stabilize the entire subsoil of the pool from an uneven state to a stable, uniform state, rather than partial repairs to stop further settlement. As a result, the entire structure was lifted by several millimeters, and at the same time, the deformation and inclination were repaired, allowing it to be restored to its original condition.

Here is a case study of a wooden house slope restoration project. "Settlement correction work and liquefaction countermeasures are different things." "You must not abuse the foundation and the ground." "A shorter construction period is better." Based on these three points, we received the request from our client. We constructed a flat foundation over an area of 89m2 using a multi-point interval method. The construction period was 12 days. As a result, the work was satisfactory, and we received words of gratitude such as, "Each role was clear, and there was no waste in the flow of the entire construction process." [Case Overview] ■ Location: Mihama, Urayasu City, Chiba Prefecture ■ Building Name: Residence ■ Structure and Scale: Two-story wooden house ■ Foundation Structure: Flat foundation ■ Total Restoration Weight: Approximately 60 t *For more details, please refer to the PDF document or feel free to contact us.

The "JOG Method" is a groundbreaking and rational approach that allows for the reliable correction and repair of unevenly settled structures through special injection alone, omitting the complex work processes required by traditional hydraulic jacks. It has numerous achievements both domestically and internationally, capable of restoring various structures, from large-scale to small-scale, with millimeter-level precision. There is no need for excavation work around the perimeter of the structure, minimizing the impact on adjacent properties with low vibration and low noise, while enabling rapid restoration with high safety and low risk. 【Features】 ■ Excellent restoration accuracy with patented technology ■ Simultaneously corrects settlement while forcibly consolidating soft ground, strengthening the foundation ■ Omits complex work processes such as excavation and relocation, reducing construction time and labor costs ■ Achieves cost reduction through significant shortening of construction periods *For more details, please refer to the PDF materials or feel free to contact us.

"GSIS" is a ground improvement system that utilizes the ground improvement technology developed through the JOG method to perform more reliable ground improvement. Based on the investigation results from the Swedish sand cone test, it allows for direct injection into the targeted reinforcement areas within the strata, enabling efficient ground strengthening with minimal loss. Since there is no excavation work and minimal impact on adjacent structures, it is well-suited for ground strengthening in areas where buildings are already present. 【Features】 ■ Specialized staff conduct investigations and collect detailed data ■ Injection is performed according to the investigation conditions of each target point to enhance ground bearing capacity ■ The quality of improvement is enhanced by combining investigation and chemical injection ■ Ground strengthening is carried out rationally without unnecessary chemical injection *For more details, please refer to the PDF document or feel free to contact us.
