MOISTURE CONTROL TECHNIQUES FOR BUILDING COVERING SYSTEMS EXPOSED TO ATMOSPHERIC PRECIPITATION
Abstract
Moisture penetration caused by atmospheric precipitation significantly affects the durability and service performance of building covering systems. Water ingress into capillary-porous construction materials accelerates corrosion processes, freeze–thaw degradation, and biological deterioration, leading to premature failure of structural elements. This research presents an engineering analysis of moisture control techniques for building coverings, including hydrophobic additives, surface hydrophobization, drainage systems, and nanomodified materials. Experimental and field data reported in previous studies are analyzed to evaluate their effectiveness in reducing water absorption and improving durability characteristics. The results demonstrate that hydrophobic treatments can reduce water absorption by up to 80%, while properly designed drainage systems decrease moisture accumulation by 60-75%. Nanomodified materials provide additional improvements in long-term moisture resistance. The study confirms that integrated moisture control strategies offer the highest performance and are suitable for practical engineering applications in modern construction.
