Moisture Barrier
A moisture barrier is a protective layer used in construction to prevent water damage in buildings. It's like an invisible shield that keeps water and dampness from getting into walls, floors, or foundations. Waterproofing professionals install these barriers using various materials like special sheets, sprays, or coatings. This is a fundamental aspect of construction waterproofing, similar to how weatherproofing or foundation sealing work. Other common names for this include "vapor barrier," "waterproof membrane," or "dampproofing layer."
