All About Terrazzo and Terrazzo Systems

Terrazzo is a composite material poured in place or precast, which is used for floor and wall treatments. It consists of marble, quartz, granite, glass or other suitable chips, sprinkled or unsprinkled, and poured with a binder that is cementitious, chemical or a combination of both. Terrazzo is cured, ground and polished to a smooth surface or otherwise finished to produce a uniformly textured surface.

Terrazzo Sustainability and LEEDS

Terrazzo was originally created in Italy over 1500 hundred years ago by Venetian workers searching for a way to use discarded marble remnants - making it one of the world's first "green" flooring system! In keeping with its original premise of recycle/reuse, today's terrazzo installations combine exceptional beauty, extreme design flexibility, durability to last the life of the building, and incredible ease of maintenance with the best practices of sustainable building. Terrazzo has long been valued for its life cycle characteristics, and can also contribute to the U.S. Green Building Council's (USGBC) credits for new construction.

Terrazzo Color Palette and Formulations

Care has been exercised in the scanning process of these illustrations to provide an image that represents the product. However, electronic imaging may not always be an accurate representation as monitors and printers vary greatly in color resolution. To ensure proper color selection, please call the NTMA office, 800-323-9736 and ask for a Color Palette.

Terrazzo is a custom flooring crafted essentially from natural products and subject to slight shade variations. Cement, both white and gray, may not be uniform in color. Since this color palette is intended for national distribution, substitutions of generally comparable aggregate (mainly marble) may be necessary or advisable in some cases. Care should be taken to assure that the aggregate supplier is a member in good standing of the NTMA and will provide all materials in accordance with NTMA standards.

The finished terrazzo should not be expected to precisely duplicate an individual color plate. Only the samples submitted by the terrazzo installer, when approved, may be considered to be a reasonably accurate representation of the finished floor, and may best serve as the basis for acceptance.

The NTMA Color Palette is intended as a guide for PRELIMINARY COLOR SELECTION ONLY. Terrazzo Contractor produced samples will not match exactly or have the same high finish.
