What They Do

• Measure designated amounts of ingredients for terrazzo or grout, according to standard formulas and specifications, using graduated containers and scales, and load ingredients into portable mixer.
• Modify mixing, grouting, grinding, or cleaning procedures, according to type of installation or material used.
• Grind curved surfaces or areas inaccessible to surfacing machine, such as stairways or cabinet tops, with portable hand grinder.
• Clean chipped area, using wire brush, and feel and observe surface to determine if it is rough or uneven.
• Grind surfaces with a power grinder, or polish surfaces with polishing or surfacing machines.
• Cut metal division strips and press them into the terrazzo base for joints or changes of color to form designs or patterns or to help prevent cracks.
• Blend marble chip mixtures, place into panels, and push a roller over the surface to embed the chips.
• Spread, level, or smooth concrete or terrazzo mixtures to form bases or finished surfaces, using rakes, shovels, hand or power trowels, hand or power screeds, or floats.

Related Careers

A Day in the Life

A terrazzo worker begins by reviewing project drawings and preparing the substrate through grinding or scarifying existing surfaces to ensure proper adhesion. They set divider strips of metal or plastic to define pattern sections, then mix and pour the terrazzo matrix of cement and aggregate precisely to achieve the correct consistency and color. After the material cures, workers use progressively finer grinding machines to reveal the marble chips and achieve a smooth, level surface before sealing and polishing to a high sheen. Project days often end with equipment cleaning and material tallying for the following day's pours.

Work Environment

Terrazzo workers spend most of their time on job sites inside commercial and institutional buildings, kneeling, bending, and operating heavy grinding machinery for extended periods. Dust from grinding operations requires respirators and eye protection, and the work involves exposure to cement and chemical sealers that require gloves and skin protection. The environment can be noisy due to grinding equipment, and workers must coordinate with other trades on active construction sites. Projects can range from small renovation jobs to multi-year stadium or airport installations, providing varied and stimulating workplaces.

Career Path & Advancement

Most terrazzo workers enter the trade through a union apprenticeship program sponsored by the International Union of Bricklayers and Allied Craftworkers, typically lasting three to four years. Apprentices begin doing prep work and mixing while learning grinding and polishing techniques under experienced journeyworkers. After journeyworker certification, skilled workers may specialize in artistic or restoration terrazzo, earning premium wages on complex decorative projects. Senior workers often advance to foreman or estimator roles, and some eventually open their own flooring contracting businesses.

Specializations

Epoxy terrazzo is a growing specialty involving resin-based systems that allow for thinner installations and more vibrant color options compared to traditional cement-based work. Restoration specialists focus on preserving and repairing historic terrazzo in landmark buildings, requiring deep knowledge of original materials and period-correct techniques. Sand cushion terrazzo for large interior slabs is a distinct specialty requiring expertise in expansion joint placement to prevent cracking in expansive installations. Exterior terrazzo on stairs, plazas, and building facades represents another niche that demands understanding of weathering, drainage, and freeze-thaw resistance.

Pros & Cons

Industry Insight

Terrazzo is experiencing renewed popularity in commercial architecture as designers and building owners seek distinctive, sustainable flooring alternatives to carpet and vinyl. Green building certifications favor terrazzo because it incorporates recycled content, emits no volatile organic compounds after installation, and lasts the lifetime of the building without replacement. The skilled craftworker shortage in construction trades means trained terrazzo workers command strong wages and face relatively limited competition for jobs. International markets, particularly in the Middle East and Asia, are investing heavily in decorative flooring for prestige commercial projects, creating export opportunities for experienced American contractors.
