[For the Construction Industry] Settlement Repair Work | Identification of Settlement Due to Buried Waste! Pressure Plate Renovation
Subsidance correction work
Identifying subsidence caused by buried waste! Reviving the foundation structure with pressure plate jacking.
In the construction industry, when planning large-scale renovations or seismic reinforcement work, debris and buried waste hidden in the gaps of ground survey data can pose a hidden risk of uneven settlement, leading to floor re-tilting or issues with fixtures after the completion of the work. No matter how much the upper structure is renewed, if the foundation or the ground beneath is left weakened, the building's inherent longevity cannot be achieved. At Geotech, we conduct hand auger drilling and pinpoint subsurface exploration as part of the ground and foundation diagnosis before starting renovations, visualizing the extent of buried waste and settlement factors as objective numerical data. In the leveling process, we apply a pressure plate jack-up method that does not require extensive demolition work, using small hydraulic jacks to achieve precise horizontal restoration in millimeter increments, leveraging the building's own weight as a counterforce. After lifting, we pressure-inject high-flow air bubble mortar into the voids beneath the floor to equalize the ground pressure, and we encapsulate the damaged cloth foundation structure with high-adhesion epoxy resin to restore structural strength beyond that of new construction. Geotech's settlement correction work menu enhances the overall quality and durability of the renovation. 【Usage Scenarios】 - When ground reinforcement and uneven settlement correction are needed - When there is a risk of settlement due to buried waste hidden in the gaps of ground survey data

Applications/Examples of results
It will be used for correcting local subsidence of existing houses caused by underground buried waste, as well as for foundation reinforcement and horizontal restoration before renovation and seismic retrofitting work. It is ideal for renovation sites that want to prevent floor re-slope issues and fixture malfunctions after the completion of renovation work, and to enhance the building's original structural strength and seismic performance beyond that of a new construction. It meets the needs of clients who want to complete structural soundness at the foundation level in a short period of time while living in the property, without incurring any costs for temporary housing or demolition work. It is widely used for differentiating technical proposals by renovation contractors and builders, as well as for proposing GeoTech's subsidence correction work menu.
