What is the primary purpose of damp-proofing on basement walls?

The primary purpose of damp-proofing on basement walls is to prevent moisture penetration from the soil into the building. Damp-proofing involves applying a barrier, typically a coating or membrane, to the exterior of the basement walls, which effectively reduces the amount of moisture that can seep through the walls from the surrounding soil. This is crucial because excessive moisture in basements can lead to problems such as mold growth, deterioration of building materials, and overall compromised indoor air quality. By implementing damp-proofing measures, contractors help protect the structural integrity of the building and ensure a healthier living environment for occupants. Other options do not accurately represent the function of damp-proofing; for instance, while aesthetic enhancement, insulation, or structural strengthening are important considerations in building, they are not the primary aim of damp-proofing systems.
