Settlement correction work | Digital measurement for foundation cracks and settlement correction epoxy pressure plate
Subsidance correction work
Prevent distortion of buildings with 3D laser measurement! Correct foundation cracks and subsidence with millimeter precision using high-adhesion epoxy resin injection and pressure-resistant slab methods.
This is a state-of-the-art settlement correction solution that resolves building settlement issues accompanied by foundation cracks with millimeter-level precision, based on visualization data management using a 3D laser measurement system. For the foundation structure that has fractured due to settlement stress, high-viscosity epoxy resin is pressure-injected to create a dense seal, restoring the integrity and waterproofing of the structure and providing seismic strength greater than that of a new building. In the lifting process, a pressure plate and hydraulic jacks are placed directly under the foundation, and ultra-high precision laser level measuring instruments and displacement sensors are linked to continuously monitor and digitally measure the building's lifting behavior and tilt angle. To accurately restore horizontal alignment with millimeter precision without causing harmful distortions or stress concentrations in the structure, it perfectly prevents secondary damage to the house, such as wall coverings tearing or beams warping. After correction, self-hardening lightweight bubble mortar (air milk) is injected at high density into the voids beneath the foundation to distribute the ground pressure evenly, completely eliminating the risk of re-settlement. We offer consistent support for construction while residents are living in the property, with a reliable ground guarantee provided.

basic information
The target is the local settlement repair of cloth foundations and flat foundations. High-viscosity epoxy resin injection and U-cut seal treatment are used for foundation repair to improve the bending and shear resistance of the structure. For measurement and lifting, ultra-high precision 3D laser level measuring instruments and digital displacement sensors are used, along with pressure plates made of steel plates with a thickness of 12mm or more (such as 500mm x 500mm) and small hydraulic jacks, allowing for millimeter-level height control. Self-hardening lightweight bubble mortar (air milk) is used as the void filling material to securely fix the ground and the foundation.

Applications/Examples of results
It is ideal for precise leveling correction of single-family homes that have experienced issues such as column tilting, poor opening and closing of doors and sashes, and tears in wall coverings due to foundational cracks and subsidence. It is chosen for sites where there is a desire to restore a level state with extremely high precision down to the millimeter, without placing excessive burden or secondary damage on the building's structural body. It is also widely used for long-term asset value preservation of homes through construction while residents are living there without temporary housing, as well as through the re-attachment procedures for ground guarantees after the completion of construction.
