What is terrazzo?

In the 16th century, Venetian marble workers recycled marble chips that were discarded from other building projects.  Mixing these leftover chips with plaster, they placed and polished the material to create floors and terraces around their homes, giving birth to terrazzo. This old world craftsmanship and technique has been passed down to each generation of terrazzo artisans. Terrazzo today is still an old world work of art.  However, most modern terrazzo incorporates the use of epoxy or modified concrete instead of plaster and cement, and is far more versatile than its 16th century counterpart.  In addition, we have the benefit of using diamonds and polishing equipment to speed up the process!

Terrazzo flooring is used to give a finished look and durable wear surface to floors, stairs, and even walls. It is highly specified in in medical facilities, universities, government facilities, and airports. Our Terrazzo Design Guide will help you discover which type of terrazzo works best for your project. With quality suppliers providing our material, we have limitless design options and can create custom color samples perfect for meeting the needs of your individual project.

In our Guide to Terrazzo Design, you’ll find that terrazzo has many more applications than just flooring. It can be used as a kitchen or bathroom counter top, or for water features and benches that add to the design of a space.

Why use terrazzo?

Terrazzo is a non-porous, extremely durable surface and is very easy to maintain.  The life cycle cost of terrazzo is far less than that of tile, carpet, and vinyl surfaces.  Be sure to get in touch with our experts on how to properly clean your terrazzo. It also has a low impact on the environment as it can be formulated to include recycled glass, and wears much longer than other flooring options.  In addition, terrazzo color and design options are limitless. These are just some of the many benefits of using terrazzo.

Which terrazzo works for me?

The type of terrazzo flooring you need will depend on the project. Some of these factors include terrazzo panel size, slab design and condition, color selection, and percentage of glass used in the mix design. Our terrazzo team can provide you with the information you will need to enjoy a successful install.

Terrazzo Design Guide

Epoxy Systems Best for interior applications. It is the most flexible and lightest of all the terrazzo styles. Resistant  to chemicals, thickness is ⅜” epoxy resin matrix on top of a concrete slab that has a flat surface. Best chip sizes are #0-1. Weight is 3-4 pounds PSF. Available dividers are in Brass, Zinc, Aluminum and plastic for Epoxy terrazzo.
Monolithic Systems The most economical cement terrazzo system, designed to adhere directly to concrete without the use of an underbed.  Although economical, this system is susceptible to cracking. Low maintenance and performs well with at least a   ½” inch thick terrazzo surface. Weight is 5-7lbs PSF.
Bonded Systems Similar to monolith terrazzo, has a sand-cement underbed to provide flatness rather than the cement providing flatness. It requires 1 ¼” up to 1 ¾” recessed expanse area to be filled to the filling depth of ½” for the terrazzo topping. Weight specifications are 18-22 pounds, PSF.
Polyacrylate System This type “breathes” the best of all the styles of terrazzo, and is ideal for replacing vinyl or carpet. Works great in high humidity areas. Best application use when applied to areas without difficulties on depth transitions and applied to an existing flat concrete slab surface. It’s  ⅜” inch thickness adds strength to allow for thinner cement systems. Recommended Chip set size is #0, 1 and 2 with a weight specification of  4 ½” lbs, PSF.
Sand Cushion Systems This premier based cement system is typically used indoors and resists mirroring to its surface.  The application is a cement topping atop a wire reinforced underbed/screed, isolation sheet and sand layer scheme. Thickness is 2 ½” to 3” that includes a ½” inch terrazzo topper.
Rustic Systems Designed for the outdoors, this style is weather resistant and has a textured surface to prevent slipping and is weather resistant.  Applicable uses are with Sand Cushion, Bonded, Structural and Monolithic systems. Thickness is ½” inch to 6” inch that includes the ½” terrazzo topping. Dividers are first used with wood and replaced by pourable joint sealants into the joints. Weight depends on the main system selected.
Precast Systems Best for flat custom surface areas such as benches, stringers, risers/stairs, planters and wall panels. These prefabrication custom units allow for unlimited uses. Thickness and or Weight vary based on the custom finish, the supplies used and manufacturing.
