Class code 5348 — Tile, Stone & Mosaic Installation

This classification covers contractors who install ceramic tile, marble, stone, and mosaic materials on floors, walls, countertops, and other surfaces. Work includes measuring and laying out patterns, cutting tile with wet saws, spreading thin-set or mortar, setting pieces, and grouting the finished surface. Jobs range from small bathroom remodels to large-scale commercial flooring installations.

Payroll includes tile setters, helpers who mix mortar and cut material, and finishers who handle grouting and cleanup. Because tile work is detail-oriented and often done in confined spaces like bathrooms, crews tend to be smaller than framing or roofing crews, but the work is no less physically demanding.

Kneeling and crouching for extended periods drives knee and back strain, while repetitive use of wet saws creates cut hazards and exposure to silica dust from cutting stone and porcelain. Handling heavy slabs of natural stone adds lifting risk, and the mortar and grout materials used can cause skin irritation with repeated contact.
