SOLUTIONS FOR DAMP MASONRY
If water is not expelled, the moisture in the masonry inevitably leads to progressive deterioration: cracking and detachment of the plaster, coatings and finishes; formation of encrustation, efflorescence, mould; and this can even compromise the structural soundness of the masonry (due to the corrosive action of the salts, such as sulphates, dissolved in the water). Rising damp is the prime cause of masonry decay (other types of humidity are derived accidentally, from construction, rain and condensation). In this pathology, the masonry absorbs the water contained in the ground which then climbs up the wall itself; it is transformed into vapour and expelled both to the inside and outside of the building. As the water rises, it deposits its salt content and these crystallize on the surfaces of the plaster, forming an encrustation that prevents moisture from evaporating and raises outward pressure. The excess water that is unable to exit, swells the wall causing the plaster to detach. The dehumidifying Tower® restoration processes are designed to counter dampness rising up from the ground, condensation caused by poor ventilation in underground areas and efflorescence due to atmospheric agents. The Tower application processes can be used on any type of masonry (brick, mixed, reinforced concrete, stone), both inside and outside the building.
