Subsidance correction work | Low-noise ground reinforcement work to correct floor tilt during renovation.
Subsidance correction work
Unexplained dizziness and headaches: Could the tilt of the floor be the cause? Restore the levelness of your home and a healthy living environment with a low-noise hydraulic jack method during renovations.
This catalog explains a sinking correction method that addresses the often-overlooked floor tilt during renovations, fundamentally improving residents' dizziness and health issues. Subtle floor inclinations caused by uneven ground subsidence can chronically stress the semicircular canals, leading to autonomic nervous system disturbances and headaches. Our company objectively clarifies the causes of subsidence through precise level measurements around the building and Swedish sounding (SWS) surveys. During construction, we carefully lift the building while monitoring its displacement in millimeter increments in real-time, using small hydraulic jacks. By employing low-noise equipment that minimizes operational sounds and vibrations, we can restore the level state within a short period without requiring residents to leave their familiar homes or move to temporary accommodations. Furthermore, by combining steel pipe pile driving into deep supporting layers and filling voids under the foundation, we thoroughly prevent future subsidence. We propose technology that enhances the structural safety of homes and realizes a safe and healthy living environment.

basic information
This method is a technology that corrects the tilt of buildings to a millimeter level using a compact small hydraulic jack and a low-noise electric hydraulic unit. For the preliminary survey, high-precision laser level measuring instruments and SWS testing machines are used to scientifically analyze the N value of the ground and the depth of soft layers. After lifting adjustments, methods such as the steel pipe pile driving method, which drives general structural carbon steel pipes (like STK400) into the support layer, or the pressure plate method are applied. Additionally, highly fluid air milk or non-shrink mortar is densely injected into the fine voids directly beneath the foundation, and high-viscosity epoxy resin is pressure-injected into the cracks to restore the durability of the foundation structure.

Applications/Examples of results
It is ideal for addressing dizziness and autonomic nervous system disorders in residents caused by uneven floors or tilting during large-scale renovations or interior improvements of detached houses. It is suitable for in-home environments where moving to temporary housing is difficult, as well as for sites in densely populated residential areas or small lots that require low-noise and low-vibration construction. Additionally, it can be widely used for restoring structural safety and preserving asset value, including partial sinking or crack repairs of cloth foundations, improving seismic resistance of existing homes that have aged, restoring differential settlement pointed out during pre-sale inspections, and resolving issues with the opening and closing of doors and windows.
