Tile work depends on substrate preparation, waterproofing, and accurate layout. Surfaces are leveled and primed; wet areas receive membranes and slope to drain. Patterns are set from control lines for balanced cuts, and the correct mortar and grout are chosen for traffic, exposure, and maintenance needs. Expansion joints, sealing, and edge trims protect the assembly and elevate the finish. The result is a durable, hygienic surface that performs under daily use while complementing the design intent.
