Damp proofing and damp treatment serve distinct purposes in combating moisture issues within buildings. Damp proofing is a preventive measure aimed at stopping water ingress from the outset. It often involves the application of a waterproof layer or coating to surfaces most susceptible to damp. On the other hand, damp treatment deals with existing moisture problems. This may include remedies like dehumidifiers, fungicidal treatments for mold, or repairs to faulty plumbing that could be contributing to damp conditions. While damp proofing is generally incorporated during construction, damp treatment is more reactionary, applied when a problem has already presented itself. Both approaches are essential for maintaining a healthy, dry living environment.
