>> The dome is a geodesic structure used as a gardening greenhouse, it does not need foundations and is removable (the structure is screwed and bolted and can be easily dismantled). If the floor area exceeds 20 m² a building permit is required. If the surface is less than 20 m² a simple declaration of work is sufficient. Technical specifications are available on request.
WEIGHT AND ANCHORAGE ON THE GROUND
>> The weight of the structure is around 150-250 kg per m². For this reason, coupled with the fact that the structure of the dome is monoblock, important foundations are not required. The smaller domes rest on a bed of gravel and are anchored to the ground with iron rods driven into the ground. Larger domes have pillars or a concrete base to provide safer anchoring. For this reason, massive foundations are not required.
FOUNDATION ISOLATION AND FREEZE LIFE
>> The earth at the edge of the dome is heated by a system of underground ducts in which hot air circulates. Polystyrene insulation boards can be buried around the edge of the dome while mounting the dome. This has the consequence of creating an isolated base which minimizes any uplift of the frost structure.
>> A structural analysis report can be provided for domes of 7.9 m, 10 m, and 12.8 m in diameter. The structures were able to withstand winds of 160 km / h and loads of 290 kg / m².
