What Is Terrazzo? Definition and Composition
Terrazzo is a composite flooring system. It's made from chips of marble, glass, and other aggregates bound with cement or a resinous binder. The material has been around for centuries. Modern formulations give you better consistency and design flexibility.
Metal divider strips separate sections or create patterns, so you can do intricate designs and control color transitions. There are two main binder types: cementitious and epoxy (resinous).
Cementitious terrazzo uses Portland cement. Epoxy terrazzo uses a two-part epoxy resin. Both can be poured in place or precast into tiles and slabs. Precast tiles are made in a factory under controlled conditions, then installed like conventional tile. Poured-in-place is mixed and installed on-site. That allows custom patterns and large continuous areas.
Terrazzo Tiles vs. Poured-in-Place Terrazzo
Terrazzo tiles come out of a factory, precast and ready to set. So you get a consistent look and a faster install. Poured-in-place terrazzo is done on site by specialized craftsmen, which gets you custom patterns and big continuous areas with no grout lines. What you pick depends on the project requirements, budget, and timeline.
Tiles come in different sizes and work on floors and walls. The aggregate chips and color are evenly distributed, so every tile matches. That uniformity is ideal for large commercial projects. Poured terrazzo gives you more design freedom. But you need skilled labor and more time for installation. Installers who really know it are worth the wait.
Types of Terrazzo Systems: Cementitious vs. Epoxy
Cementitious terrazzo splits into monolithic, sand cushion, bonded, rustic, and polyacrylate. It runs thicker and heavier than epoxy. And you can put it outside. Sand cushion sits over a wire-reinforced mud bed of sand and cement mix. That base keeps things stable and helps stop cracking.
Epoxy terrazzo is thin-set, usually 1/4 to 3/8 inches. Interior only. It won't survive outside. Installation moves faster. You get a wider color range, and it resists cracking better than cementitious. Epoxy now dominates current construction.
| Property | Cementitious Terrazzo | Epoxy Terrazzo |
|---|---|---|
| Binder | Portland cement | Epoxy resin |
| Thickness | Thicker than epoxy | Thin-set (1/4 to 3/8 inches) |
| Weight | Heavier | Lighter |
| Moisture tolerance | Better for moist environments | Not suitable for exterior or wet areas |
| Crack resistance | Moderate | Excellent |
| Installation speed | Slower | Faster |
| Color range | Limited | Wide |
What Is Terrazzo Made Of? Aggregates and Binders
Marble, granite, quartz, glass, shell, mother-of-pearl. It all goes in. Recycled materials show up often, post-industrial or post-consumer glass, marble, granite, onyx. That is why it gets called eco-friendly. The binder is cement or epoxy resin. Add pigments to the binder and you can get a wide range of colors.
Aggregate size controls the look. Large chips give a bolder, more textured surface. Small chips make a finer, more uniform one. The ratio of aggregate to binder matters too. Traditional cementitious terrazzo uses 2 parts marble aggregate to 1 part cement.
Durability and Lifespan of Terrazzo
Terrazzo lasts the life of the building. That is not an exaggeration. A floor with basic maintenance will still be there decades after the first tenant moves out.
How long depends on the binder, the install, the traffic, and how it is cleaned. Dull or scratched? Refinish it and it looks close to new, which buys you another stretch of years without replacement.
Vinyl and carpet wear out and need to be pulled up. Terrazzo does not. In a busy lobby or corridor, replacing flooring shuts things down and costs real money. Terrazzo sidesteps that problem.
Applications: Where Is Terrazzo Used?
Airports, schools, hospitals, retail, offices. Terrazzo shows up there because it takes heavy traffic and asks for little in return. Those same qualities push it into homes too, often as tiles in kitchens, bathrooms, living areas.
Floors, walls, countertops, stairs. Terrazzo does all of them. Cementitious terrazzo with a rustic finish works outdoors. Epoxy terrazzo stays inside. And terrazzo tiles hold warmth, so they pair well with underfloor heating.
Pros and Cons of Terrazzo
It holds up. Durable, low maintenance, and you can design with it. Tiles work where foot traffic is heavy. Seal them once and they resist moisture. Using recycled materials helps, and a long life makes it eco-friendly.
But it costs more upfront. The surface is cold and hard underfoot. It can also crack. You need to seal it.
Epoxy terrazzo will not work outside. Skilled labor is required for installation. That adds cost and time to the project.
Cost Considerations for Terrazzo
What you pay comes down to system, aggregate, and design complexity. Epoxy costs more per square foot than cementitious, but its thinner profile can mean less structural work. Go with precast tiles and you often save money over custom poured. That is true on small jobs and renovations.
It can be pricey up front. Low maintenance and long wear balance that out over the life of the building. Commercial work is where terrazzo gets called for when durability and easy cleaning matter. That is where it earns its keep.
Maintenance and Care of Terrazzo
Sweep it. Mop with a neutral pH cleaner. That covers daily dirt. Seal it now and then, especially in heavy traffic or kitchens, so stains don't soak in.
Dull? Re-polish and the shine comes back. But keep acid and abrasive cleaners away. They etch the surface or eat at the binder. Cementitious terrazzo? You'll reseal more often than you would with epoxy.
Specifying Terrazzo for Commercial Projects
On big jobs you decide early: system type, aggregate, divider strip layout, finish. Get samples early. Color and aggregate distribution don't show up in a spec sheet, but they show up on the floor. Sourcing overseas? Ask for third-party inspection reports and factory audit documentation. Reputable manufacturers keep those ready to send.
Installation oversight matters. Some suppliers will send an architect or construction team to guide on-site work. That is the difference between proper installation and a call next year. If your project is in Africa or another far region, confirm shipping terms and lead times early. Do it during planning, not after.
Terrazzo in Different Climates and with Underfloor Heating
Climate changes the binder choice. Cementitious terrazzo can go outside in moderate weather. Epoxy stays indoors. Humid or wet spots? Cementitious systems usually win because they handle moisture better.
Terrazzo holds heat, so it pairs well with underfloor heating. That is why it shows up in homes and commercial buildings in cold regions. The thermal mass spreads warmth evenly, which improves comfort and cuts energy use. No surprises there.
Buyer's Checklist for Sourcing Terrazzo from Overseas
Check the manufacturer's experience and production capacity. Ask for samples. They're free, but you pay international shipping. Confirm the binder type and aggregate composition, and ask about warranty support plans, not just the sales pitch. Clarify shipping terms: FOB Foshan/Guangzhou, CIF, or EXW. For door-to-door delivery, some African countries are covered.
Winway started in 1997 in Foshan, China. That's more than two decades in building materials supply. The company sells terrazzo tiles and porcelain tiles. A sales team of over 200 people ships to more than 100 countries. For more information, contact Winway.
Terrazzo is a composite flooring system. You mix cement or resinous binder with chips of marble, glass, and other aggregates. That's from the International Masonry Institute. Epoxy terrazzo is thin-set. It goes down at 1/4 to 3/8 inches thick, as noted by Terrazzco.
