Sinking correction work | Solving dizziness issues through floor tilt analysis and leveling of the home.
Analyzing the unpleasant dizziness induced by the tilt of the floor! Resolving housing defects and health issues through objective data from building perimeter level measurements and correcting subsidence while living in the home.
Ground subsidence and floor tilting that occur after the handover of a house are serious issues that can cause not only damage to fixtures and walls but also health problems for residents, such as dizziness, headaches, and nausea. GeoTech's subsidence correction solutions provide a rapid and reliable repair plan based on objective evidence for builders and housing manufacturers in after-sales service and defect warranty situations. First, we conduct high-precision measurements of the building's perimeter level, digitizing and analyzing the height differences and deformation angles around the building down to the millimeter. Based on this visualized data, we plan and execute "subsidence correction while living in the house," which eliminates the need for temporary housing or relocation for the homeowner. This approach avoids secondary costs such as moving expenses and minimizes the mental burden on residents. Furthermore, we strengthen the structural foundation from the ground up through precision lift-up using the "i-LIFT method" and by reinforcing the foundation structure with the "Ganko Oyaji method." We fulfill our technical accountability and ensure the long-term health of residents and the reliability of their valuable housing assets.
basic information
The target structures are general single-family houses and small buildings constructed using wooden frame construction, lightweight steel frame, and reinforced concrete (RC). The survey methods employ high-precision laser level measuring instruments, displacement sensors, and SWS testing machines to quantify the tilt angle and settlement amount in millimeters through measurements of the building's perimeter level. The construction methods include liquid pressure injection (i-LIFT method), steel pipe pile driving method, pressure-resistant slab method, and carbon fiber foundation reinforcement (Ganko Oyaji method). The construction equipment utilizes a compact electric power unit to achieve ultra-low noise and low vibration construction on-site.
