We would like to introduce our "Underpinning Method." This method involves excavating directly beneath the sunken foundation and using hydraulic jacks to return the tilted house to a level position. By using steel pipes driven into stable ground as support piles, there is a reduced risk of re-sinking, making this a reliable method for the future. Additionally, depending on the specifics, a 10-year warranty is also available for this method. 【Features】 ■ Excavate directly beneath the sunken foundation and use hydraulic jacks to level the tilted house ■ Use steel pipes driven into stable ground as support piles ■ Reduced risk of re-sinking, ensuring future reliability ■ A 10-year warranty is also available *For more details, please refer to the catalog available for download below "PDF Download."

We would like to introduce our "Pressure Plate Method." This method is used for repair work when the supporting ground is shallow (approximately 1.5m). After excavating beneath the settled foundation, a steel plate is installed, and pressure is applied using hydraulic jacks to create a stable ground. This pressure plate serves as a reaction force for correcting the settlement. 【Features】 ■ Used for repair work when the supporting ground is shallow (approximately 1.5m) ■ After excavating beneath the settled foundation, a steel plate is installed, and pressure is applied using hydraulic jacks to create a stable ground. *For more details, please refer to the catalog available for download below.

We would like to introduce our "Foundation Raising Method." This method is used for the repair of buildings where ground subsidence has stabilized. It involves partially dismantling the foundation top and leveling the superstructure above the foundation using jacks. Please feel free to contact us if you have any inquiries. 【Features】 ■ Repairs buildings where ground subsidence has stabilized ■ Partially dismantles the foundation top and levels only the superstructure above the foundation using jacks *For more details, please refer to the catalog available for download below as "PDF Download."
