Traffic and machinery vibration countermeasures: Ground replacement method "Columbus+"

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.
