Traffic and machinery vibration countermeasures: Ground replacement method "Columbus+"
Ground Replacement Method Columbus+
Traffic and machine vibration countermeasures: Vibration reduction effects demonstrated in experiments by the Better Living Foundation.
【(Foundation) Better Living's experiment has demonstrated the effectiveness of vibration reduction】 【The Hokkaido Northern Architecture Comprehensive Research Institute has verified and evaluated the effects of insulation and frost prevention】 【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 the building on soft ground and suppressing settlement. Furthermore, both "Geoform" and "foam drainage material" have a vibration reduction effect. The effectiveness of this vibration reduction has also been demonstrated in experiments by (Foundation) Better Living. ○ Pre-cut Geoform will be delivered according to the construction drawings, making installation easy. ○ We guarantee protection against damage to the foundation and building due to differential settlement, for up to 10 years and a maximum of 50 million yen. ○ We have 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. Local representatives will visit to provide explanations. ○ Estimates are free of charge. ○ For more details, please contact us or download the catalog.

basic information
【Traffic and Mechanical Vibration Countermeasures】 The ground replacement method "Columbus+" not only prevents differential settlement but also reduces vibrations transmitted to the ground. This is because the "Geoform" and "Foamed Drainage Material" used in the Columbus+ method serve as cushioning materials. The foamed resin body consists of over 98% air, which reduces vibration waves through this air layer. Additionally, depending on the level of vibration, we select materials with excellent vibration isolation performance. 【Raw Materials for Geoform and Foamed Drainage Material】 ■ Expanded Polystyrene: Reduces load. Also used as a material for EPS civil engineering methods (ground measures when constructing roads, etc., on soft ground). ■ Expanded Polypropylene: A material with excellent chemical resistance, weather resistance, and vibration isolation performance, used in automotive bumpers. ■ Expanded Polyethylene-Polystyrene Copolymer: A material with excellent chemical resistance, weather resistance, and vibration isolation performance. Geoform utilizes these raw materials, selected based on application and usage environment as molded ground materials. 【Application Range and Conditions】 ○ Building weight: 6t/m² or less (suitable for wooden to steel structures, approximately 3 to 4 stories of RC construction) ○ Must be a flat foundation. ○ Can accommodate an N value of 0.
