Capillary rising damp represents one of the most insidious and widespread building pathologies, capable of severely compromising the structural integrity of buildings and the living quality of rooms. This complex physical phenomenon occurs when water present in the ground rises through capillaries in masonry, carrying with it mineral salts that, as they crystallize, cause efflorescence, spalling and progressive deterioration of materials.

DWALL® is presented as the technologically advanced solution to permanently addressrising capillary damp. SB Bio Building sagl's dehumidifying coating was designed through a rigorous scientific approach that takes into account the fundamental mechanisms that govern this pathological phenomenon.

The operating principle of DWALL® is based on a thorough understanding of masonry water balance. In masonry affected by capillary rising damp under equilibrium conditions, the amount of water absorbed from the soil is exactly equivalent to the amount of water evaporating from the surfaces. The DWALL® system intervenes by altering this balance through its unique evaporative capacity, significantly accelerating the process of moisture disposal without undergoing degradation by salts.

The technology behind DWALL® incorporates a NOBILUM-THERMALPANEL insulation panel made of natural fibers of pure basalt rock, a material characterized by exceptional vapor migration and breathability properties. This component, integrated with a specific anti-salt system and a natural mineral finish reinforced with glass fiber, creates a dehumidifying barrier that provides a vapor passage resistance value of μ3, optimizing the migration of moisture to the outside.

The anti-salt formulation is a distinctive feature of the system. While traditional rehabilitation interventions often fail due to the aggression of crystallized salts, DWALL® maintains its effectiveness over time, resisting chemical degradation processes and preserving its original dehumidifying properties.

The methodological approach of DWALL® involves a thorough preliminary analysis that considers the specific environmental pathology and building history. This diagnostic phase allows customizing the intervention, precisely identifying the causes of the problem and calibrating the solution to the specific characteristics of each masonry.

The DWALL® system is distinguished by its total reversibility, a fundamental principle that respects the canons of conservative restoration. This feature allows interventions that do not compromise the original structure of the building, maintaining compatibility with historic materials and ensuring the possibility of future modifications without permanent damage.

The effectiveness of DWALL® in controlling rising damp translates into tangible benefits: elimination of salt efflorescence, stopping structural deterioration, improving energy efficiency and creating healthier environments. The system represents a strategic investment in the preservation of the building heritage, offering a permanent and lasting solution to the problems of rising damp.
