Understanding Terrazzo: Types and Composition
Terrazzo combines aggregates like marble chips or glass particles with a binder. This composite material offers exceptional durability. Two primary binder types dominate the market: cement and epoxy. Each system creates different performance characteristics.
Cementitious vs. Epoxy Terrazzo
Cement terrazzo uses a Portland cement binder. This traditional option provides a matte finish. Cement terrazzo works well for interior applications. Epoxy terrazzo uses a resin binder. This system delivers a glossy finish. Epoxy also allows thinner installations than cement. Choose epoxy for maximum durability.
Your choice between epoxy vs cement systems depends on project needs. Consider the installed cost. The table below shows typical ranges.
| Terrazzo Type | Installed Cost Range (per sq ft) |
|---|---|
| Epoxy terrazzo | $25 – $90 |
| Sand-cushion (cementitious) | $40 – $80 |
| Monolithic | $30 – $70 |

Terrazzo Specification and Installation Guide
How to Specify Terrazzo Floors Effectively
Writing a terrazzo specification requires a step-by-step approach. You start with performance criteria. For healthcare facilities, you must meet strict standards. Slip resistance demands a static coefficient of friction of 0.5 or higher for level surfaces. Wet areas like showers require a dynamic COF of 0.6 or higher. Chemical resistance must meet ASTM F925 thresholds. Static load limits follow ASTM F970. Fire resistance requires ASTM E648 critical radiant flux compliance. You also need floor flatness of FF 35 or higher for operating rooms per ACI 117 tolerances.
Your terrazzo specification should address aggregate selection next. You choose aggregate sizes based on the visual effect you want. Standard-size aggregates provide optimal thickness for slip resistance. You can select marble, quartz, or glass particles. Each aggregate type creates a different aesthetic. You also define the binder system. Epoxy delivers superior stain resistance and a glossy finish. Cement offers a matte, natural appearance. Your specification must state which binder you require.
Finish requirements form the third component. You specify the level of gloss or matte appearance. You also define joint placement and pattern layouts. For high-infection-control areas, you need monolithic and seamless assemblies. The integral wall base should extend six inches up the wall. Your specification must include moisture testing per ASTM F2170 or F1869. Post-installation verification includes adhesion testing and documented commissioning. State health departments often require these steps.
Coordinating with Suppliers and Installers
You should coordinate with suppliers like G·ONE early in the design phase. Early coordination ensures feasibility and realistic lead times. You can request samples and digital catalogs. You can also discuss custom colors and aggregate blends. This collaboration prevents costly changes later. Your specification guide should include supplier contact information and reference standards.
Installation requirements vary between cementitious and epoxy systems. Substrate preparation matters for both. You must ensure the floor is clean, level, and dry. For occupied floors, you may need acoustic underlayment. Crack isolation membranes protect against substrate movement. Moisture vapor suppression systems prevent moisture issues. These components belong in your specification.
Joint placement requires careful planning. You place control joints to accommodate movement. Expansion joints allow thermal expansion. Your installer must follow manufacturer specifications. Industry standards from RFCI or TCNA guide proper installation. Heat-welded seams may be required for certain applications.
Curing times differ between systems. Epoxy cures faster than cement. Epoxy typically cures within days. Cement requires longer curing periods. You must allow adequate time before foot traffic. Poured-in-place terrazzo demands skilled labor and careful site conditions. Precast terrazzo slabs simplify installation. You avoid on-site mixing complexity. Precast options arrive ready for placement.
Your cost and planning analysis should include installation timelines. Faster installation reduces labor costs. Epoxy systems often have higher upfront costs. However, epoxy offers lower maintenance over time. Cement requires periodic sealing. You should evaluate the total lifecycle value. This analysis helps you make the best financial decision.
