Ceiling installation plays a crucial role in waterproofing, especially in areas exposed to moisture, such as bathrooms, kitchens, and basements. Proper waterproofing prevents water damage, mold growth, and structural deterioration by using moisture-resistant materials like PVC, cement boards, and coated gypsum panels. Additionally, applying waterproof membranes, sealants, and water-repellent paints enhances protection. Proper ventilation and drainage systems help control humidity and prevent condensation buildup, reducing the risk of leaks and long-term damage. Regular inspections and maintenance ensure the effectiveness of waterproofing, preserving the integrity and durability of the ceiling structure.
