Subsurface Obstruction Countermeasure: Ground Replacement Method "Columbus+"

basic information

What is underground buried object hazard countermeasure? "Underground buried object hazard" refers to foundations, concrete blocks, existing piles, etc., that were not removed during previous demolition work and are buried underground. Their existence becomes apparent during ground surveys before construction or during demolition work. In other ground improvement methods, removal costs may increase, or it may not be possible to address the situation if there are underground buried objects. However, with the Columbus+ method, it is possible to address the issue by only removing rubble or similar materials where there is contact. Scope and Conditions: - Building weight: 6t/m² or less (from wooden to steel structures, approximately 3 to 4 stories for reinforced concrete) - Must have a flat foundation. - Can accommodate an N value of 0.
