Settlement correction work | Repairing settlement cracks in the fabric foundation using SWS investigation and partial jacking.
Subsidance correction work
Investigating the causes of partial subsidence of the foundation and structural cracks through SWS surveys! We will reliably restore the client's trust with partial jacking up and re-attaching ground guarantees.
This plan is a solution for contractors and house manufacturers that covers everything from the scientific clarification of the causes of partial subsidence of the foundation and structural cracks that occur in homes after delivery, to precise corrections and warranty provisions. By conducting SWS (Screw Weight Insertion) tests and high-precision measurements of the building in advance, we visualize the factors of uneven subsidence in the ground and present a correction plan based on clear evidence. We adopt an approach of "repairing while living" that does not require temporary housing or moving, and we prevent secondary complaints through thorough site management with dust protection and low-noise construction. In the construction process, we use a small hydraulic jack in conjunction with a laser measurement device to accurately return the building to a level position without applying pressure to it, down to the millimeter. Along with repairing foundation cracks, we perform permanent ground reinforcement using steel pipe piles and pressure plates, providing a one-stop solution that includes reissuing ground warranties. We aim to transform the trust of clients who have been discouraged by troubles into a solid positive impression by providing "greater peace of mind than at the time of new construction."
Inquire About This Product
basic information
The target structure is a wooden single-family house and lightweight steel frame (compatible with cloth foundations). The investigation specifications include SWS testing (4 to 7 points) and high-precision laser measurements of the internal and external floor levels. For correction equipment, we will use a small hydraulic jack (capacity 5t to 20t), a portable electric hydraulic pump, and a three-dimensional displacement monitoring sensor. As repair and reinforcement materials, we will use high-adhesion epoxy resin injection material, STK small-diameter steel pipes (pile diameter 101.6mm to 139.8mm), and steel pressure-resistant plates. For curing specifications, we will standardly equip dust-proof masking and floor protection sheets to fully accommodate construction while residents are present.

Applications/Examples of results
It is ideal for aftercare of residential properties within the defect liability period, as well as for single-family homes where partial settlement, cracks, and poor fittings have occurred due to soil consolidation and ground weakness. It is utilized for responding to clients who wish for rapid repairs while living in the property, as well as for construction companies, house manufacturers, and warranty companies looking to minimize temporary housing costs and achieve early resolutions for complaints. It is widely used to ensure the safety of the building structure and to provide long-term asset value and peace of mind through the reattachment of ground warranties.
