The absence of humidity and mould must be ensured both in new buildings and in the recovery of existing buildings.
Before any redevelopment intervention, it is essential to look into the presence of wet mass and other forms of deterioration of the walls. The constant presence of humidity due to capillary rise, condensation or infiltration makes an environment unsanitary because it influences the internal microclimate and promotes the proliferation of mould and bacteria. Humidity also has an extremely negative impact on the insulating properties of the envelope.
An in-depth inquiry on the origin of the humidity in the walls is the first intervention to be performed in order to identify the most appropriate solutions to the problem.
