Settlement correction work | Partial repair of settlement and cracks in the cloth foundation with steel pipe piles while residing.
Subsidance correction work
No need to move; construction can be done while living in the space! Smartly repair local subsidence and cracks in the fabric foundation using steel pipe pile driving methods, minimizing costs and construction time with partial reinforcement.
The sinking and cracking of strip foundations caused by the aging of residential buildings and localized ground softening lead to issues that result in stress in daily life and a decrease in the asset value of the property. Large-scale demolition and reconstruction or house-moving work require high costs and temporary housing, but with Geotech's steel pipe pile driving method, it can be safely and reasonably corrected while living in your familiar home. This method utilizes the building's own weight as a reaction force to steadily drive steel pipe piles down to a stable support layer using a small hydraulic jack, accurately jacking up and correcting the sinking areas. Since it can be constructed with partial excavation, the construction period can be minimized, optimizing construction costs. Additionally, high-viscosity resin injection is applied to the cracks in the damaged strip foundation, and lightweight, durable air milk is filled and injected into the voids created by sinking under the floor and underground to restore ground bearing capacity. It generates minimal vibration and noise for neighbors and is the definitive method for correcting residential sinking with excellent cost performance. We will continue to support your important home with a reliable construction system.

basic information
Standard construction materials will use general structural carbon steel pipes (JIS G3444 STK400, etc., with an outer diameter of 114.3 mm or more and a wall thickness of 4.5 mm or more). Manual and hydraulic jacks will be used in combination to continuously drive small-diameter steel pipes, with a diameter of 0.7 to 1.0 m, into the ground, using the weight of the building as a reaction force. The support capacity will be confirmed by penetrating more than 2 m into a hard layer with a converted N value of 10 or more, as determined by ground investigation (SWS tests, etc.). High-permeability epoxy resin and sealants will be applied to the cracked areas of the foundation, and air-entrained mortar will be injected under high pressure into subsided or void areas. The structural stability and support capacity will be strictly verified and fixed according to our company's regulations.

Applications/Examples of results
It is widely used for repairing the sinking of cloth foundations in single-family homes and apartments that have aged, as well as for restoring partial cracks. It is ideal for renovation sites where residents want to avoid temporary relocations and for clients who wish to reduce construction costs while enhancing the seismic resistance and correcting the tilt of the foundation. It is effective for construction on narrow sites where large heavy machinery cannot be brought in due to limited space between neighboring properties. Additionally, it is extensively utilized for preventing voids in the subfloor ground, stabilizing cloth foundations that have experienced localized uneven sinking, and for partial reinforcement and functional restoration work on foundations aimed at prolonging the lifespan of buildings.
