Construction Works of a Dome House in Nyúl
At this point the underground level of stage 1. can be seen. In some places the excavation of fertile soil exceeded 3 meters in depth, to reach under ground level. On this level a strip foundation was executed and filled with granules in a 23-cm compacted layer. The granules were placed on the undisturbed soil. On this layer a 12 cm thick reinforced concrete slab was placed, followed by the waterproofing insulation and a 6 cm thick blind concrete.
An interesting feature of the structure is that between the reinforced concrete slab and the blind concrete no thermal insulation has been placed, since this is solved with the foam glass installed underneath. Using this method, according to the architect, a so-called "thermal storage" will be created, because the thicker the concrete, the slower it grows cool.
Stage 2. is scheduled in September, when the thermal insulation of the ground floor will be executed, followed by the external vertical insulation of the walls in the spring of 2019.
