The deterioration of balconies is mainly due to phenomena directly or indirectly related to the weather and rainwater runoff. Rainwater is detrimental to each and every part of the balcony (frontals, flooring, intrados, railing), causing different types of deterioration: swelling; damage; detachment which lead to exposure of the underlying load-bearing layer; exposure of the reinforcing steel, all the way to ejection of the reinforcement cover. All these cases require specific, differentiated repair.
The deterioration can be slowed, if not prevented, through some expedients and specific technical devices, both during construction and during any renovation: proportioning and positioning of covers and weather-boards; installation of drain elements; sloping; sheathing and waterproofing to ensure correct water runoff; use of expansion joints and elastic seals to absorb tensions (caused by dimensional variations, structural settling, freeze-thaw cycles, etc.).
