Settlement correction work | Partial correction of settlement and cracks in the fabric foundation during occupancy completed with SWS investigation.
During residence, we will clarify the sinking and cracks of the slab foundation through SWS investigation! We will ensure safe construction while protecting your life with partial jack adjustments, eliminating the need for temporary housing.
This plan is a resident-friendly subsidence correction solution that precisely and safely repairs partial subsidence of the foundation and structural cracks while protecting the daily lives of residents. By conducting a pre-implementation SWS (Screw Weight Insertion) test and high-precision measurements of the floor levels inside and outside, we visualize the localized causes of subsidence and the unevenness of the ground. Based on the diagnostic results, we ensure dust prevention measures and safe pathways to prevent dust from entering the living space, and we carry out partial jacking using small hydraulic jacks. By lifting and correcting in millimeter increments while monitoring the building's minute movements in real-time with a 3D laser level measuring device, we can restore it to a level position without placing undue stress on walls or columns. For foundation cracks, we apply epoxy resin injection and, if necessary, use steel pipe pile driving and pressure plate reinforcement to prevent re-subsidence. We promise to achieve a worry-free construction process that incurs no temporary housing costs or moving expenses, minimizing the mental and financial stress for the client.
basic information
This specification addresses local subsidence correction for wooden houses under occupancy (with a cloth foundation structure). The investigation system includes SWS (screw weight penetration) testing and laser level measurements of indoor floors and foundation tops. The lifting mechanism employs small multi-stage hydraulic jacks (capable of 5t to 20t) and portable electric hydraulic pumps, along with 3D displacement monitoring sensors. For structural repair, epoxy resin injection materials and U-cut seal materials are used, while ground reinforcement utilizes small-diameter steel pipes (STK materials) or steel pressure plates. Dust-proof masking and blue sheet protective coverings are standard equipment.

Applications/Examples of results
This is ideal for single-family homes where homeowners want to repair partial subsidence or cracks in the foundation while still living in the house, making it perfect for families raising children or those working from home. It can be used by homeowners who want to eliminate the costs of temporary housing and the hassle of moving, as well as by house manufacturers and construction companies for after-sales maintenance to effectively prevent secondary complaints. It can be widely utilized to quickly resolve issues such as misalignment of fixtures and floor sloping while maintaining comfort and privacy in living spaces, thereby restoring the safety and asset value of the home.
