Site Investigation | Prevention of Settlement Defects in Uneven Ground at the Site of a Demolished Wooden Apartment Building

Quantify the risk of uneven ground subsidence lurking in the site of a demolished structure through multi-point penetration tests, in order to prevent accidents and defects after the handover of wooden apartments.

This technology is a ground diagnosis service that precisely identifies the risk of uneven ground subsidence lurking in the demolition site of wooden apartment buildings, preventing uneven subsidence accidents and defect liability issues after handover. In the demolition site of old structures, insufficient compaction of backfill soil and underground obstacles can easily lead to significant strength discrepancies within the site, raising concerns about tilting incidents occurring after the building's completion. This service employs multi-point screw weight penetration tests (SWS tests) to meticulously measure penetration resistance values at various depths, visualizing uneven strata structures and localized weak areas. By calculating and simulating the estimated deformation angles (building tilt) from the resistance differences between measurement points, we quantitatively verify the impact on the structure. By providing objective and highly reliable ground data along with detailed analysis reports, we facilitate the smooth passage of third-party ground guarantee reviews and dramatically reduce after-risk for business owners and builders. We protect the asset value and business reliability of the completed apartments over the long term.
