Kerto Ski



Sliding foundation is a modular foundation adapted to light buildings that needs to be easily moved to a different place. It can be used in harsh environments as deserted zones, where it can be filled in with sand to assure the building stability to wind efforts. It is prefabricated with 3 horizontal pieces in Kerto S (machined to retrieve a ski form), overlapping 2 columns in Kerto Q. The columns are 0.50m height to allow the natural ventilation of the slab. All the elements are glued and screwed. A metallic plate is screwed to the Kerto Ski to assure timber protection and sliding comfort. A couple of sliding foundations at a distance of 3m can support a dead load of 100 daN/m² and a live load of 150 daN/m². A Kerto Q slab (75mm thick) can be used for a 3m-span flooring. The total amount of Kerto needed for the couple of sliding foundations and the slab is 1.5m3. The couple of sliding foundations costs 2k€. The building on the sliding foundations can be a light beams and posts twin elements folded-out for an easy transport and a quick on-site assembly.
