This comprehensive waterproofing and tiling system is designed for submerged environments, providing reliable water protection and durable tile installation in swimming pools, water tanks, and other permanently wet areas. It combines a flexible cementitious waterproofing membrane with a high-performance flexible tile adhesive and a water-repellent cementitious grout. The waterproofing layer withstands significant positive and negative water pressure while bridging hairline cracks, whereas the adhesive ensures strong bonding and flexibility under slight substrate movement. The finishing grout offers excellent water repellency, abrasion resistance, and shrinkage-free performance, ensuring long-term durability and protection in demanding submerged applications.
