Concrete, metal, or wood—all building materials degrade over time when exposed to water and moisture. Moreover, every building element is exposed to weathering to varying degrees, from the foundation to the roof. Consequently, protective layers must be incorporated to prevent water from contacting raw materials—a process known as waterproofing—ensuring the structure's maintenance and longevity.
For metals, for instance, whether in structural beams and columns or in gutters and flashing on roofs, contact with water causes oxidation and a subsequent loss of strength. To prevent this issue, waterproofing is achieved by applying an anti-corrosive primer followed by a topcoat that enhances mechanical protection. Wood, on the other hand, as an organic material, is prone to rotting when exposed to water and moisture. It therefore requires the application of varnishes and resins that create a protective barrier, allowing it to be used structurally as well as in interior and exterior finishes.
