Foundation repair work | Correcting floor tilt to alleviate dizziness! Ground reinforcement work while living in the house.
Subsidance correction work
Eliminate dizziness caused by the tilt of the floor! Completely restore the health and safety of your home with precise leveling measurements and a low-noise hydraulic jack method that allows for repairs while living in the space.
The uneven settlement of residential buildings and the tilting of floors due to aging can cause persistent stress to the vestibular system and autonomic nervous system of the residents, leading to unexplained symptoms such as dizziness, headaches, and nausea. The settlement correction work provided by Geotech Co., Ltd. is an advanced technology that fundamentally resolves these unpleasant symptoms and restores a healthy living environment in homes. Before construction, laser measuring devices and leveling instruments are used to visualize the tilt of the building's exterior and interior in millimeter detail, and optimal repair designs are planned based on objective technical data. During the actual correction work, low-noise and low-vibration multi-stage hydraulic jacks are used to accurately lift the tilted foundation structure to a horizontal state, utilizing the weight of the building and ground reaction forces. This process does not require any relocation to temporary housing, allowing the construction to be completed while maintaining essential living infrastructure such as water and gas, thus avoiding unnecessary secondary costs and mental burdens. After construction, resin injection into foundation cracks and air milk filling into ground voids are carried out to ensure permanent stabilization and prevention of re-settlement.

basic information
This sinking correction method employs lightweight and compact multi-stage hydraulic jacks and low-noise electric hydraulic units as the main equipment. The reinforcement methods include a steel pipe pile driving method using general structural carbon steel pipes with a grade of STK400 or higher (with a pile diameter of 114.3mm or more and a wall thickness of 4.5mm or more), a pressure-resistant slab method using steel plates with a thickness of 12mm or more as a reaction plate, and the i-LIFT method, which involves pressurized injection of quick-setting cement-based grout materials. For level monitoring during construction, high-precision laser level measuring instruments are used to control the elevation displacement in millimeter increments. Additionally, high-adhesion epoxy resin and high-flow bubble mortar (air milk) are applied for foundation crack repair.

Applications/Examples of results
It is used for leveling the uneven floors and correcting differential settlement in renovation work for detached houses, mixed-use residential buildings, and existing wooden houses. Since it can be carried out while residents are still living in the property, it is ideal for home renovation projects where moving or temporary housing is to be avoided. Furthermore, it is also implemented for improving living environments to prevent and alleviate health issues such as dizziness, headaches, and nausea caused by floor tilting, as well as resolving opening and closing issues with doors and windows due to poor fitting. Additionally, it is widely used for pinpoint repairs of localized subsidence or cracks in strip foundations, and for ground reinforcement to prevent future subsidence.
