Is removed

The first stage of work is the same for all types of foundation — this is the preparation of a bed for a multi -layer “pie”, on which paving stones will subsequently be laid. For this purpose, the upper layer of soil is removed, or the coating designed to replace is dismantled. The depth of soil excavation depends on the type of base-for a light “pedestrian” base, this is 10-15 cm, for “heavy” bases-20-30 cm.
