Subsurface Obstruction Countermeasure: Ground Replacement Method "Columbus+"
Ground Replacement Method Columbus+
[Underground Obstruction Countermeasures] Can accommodate underground obstructions such as rubble and existing piles!
【(Foundation) Better Living's experiment has demonstrated the effectiveness of vibration reduction】 【The Hokkaido Northern Architecture Comprehensive Research Institute has verified and evaluated the insulation and frost prevention effects】 【Patent construction method】 The ground replacement method "Columbus+" removes heavy soil beneath the foundation and replaces it with lightweight and compression-resistant "Geoform," reducing the weight of buildings on soft ground and suppressing settlement. Additionally, the Columbus+ method can accommodate underground obstructions such as rubble and existing piles, which are difficult for other ground improvement methods to handle. It is sufficient to remove only the rubble in contact with the Columbus+ method, and existing piles can be left in place as long as the contact areas are removed. ○ Pre-cut Geoform will be delivered according to the construction drawings, making installation easy. ○ We guarantee no damage to the foundation or building due to differential settlement. For 10 years, up to 50 million yen. ○ A track record of 4,000 projects nationwide, from public properties to general residences (as of August 2020). ○ We are expanding offices and agents nationwide. A local representative will visit to provide an explanation. ○ Estimates are free of charge.

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.
