The ideal ground for a terrace is a concrete slab at the height of between 6-7 cm from the edge of the exit point. Alternatively, the terrace can be placed on a gravel basis using classic concrete slabs to keep the moisture away. This allows for the airiness of the terrace since otherwise, the moisture starts to bend the wood and causes it to rot and decay. The terrace must be built before the parquet floor is installed in places with no access from the outside because the floor already installed can be damaged by manipulation and cutting of the material. We also avoid dirt and dust in this way. On already done premises, installing a terrace on the balcony is more demanding as it requires more time, which means increased costs.
