Defining Terrazzo: What makes terrazzo?

Defining Terrazzo: What makes terrazzo?

Defining Terrazzo:

What makes terrazzo?

Terrazzo flooring has a long and rich history that dates back over 1,500 years. The word terrazzo originated from the Italian word for “terrace,” and it was created by Venetian marble workers discovering new uses for discarded marble chips.

With today’s building technologies, terrazzo designs can now offer a nearly limitless array of colors, with enough flexibility to accommodate designs from very simple and classic to extremely intricate and complex. All while retaining terrazzo’s durability, sustainability, and low maintenance costs.

But what makes terrazzo?

Matrix

The terrazzo matrix is the binding material, either epoxy resin or cement, that bonds to the underlying structure. The matrix contributes to the overall color.

Aggregate

Terrazzo can contain a large variety of chips or aggregates including marble, granite, and glass. It can also include decorative glass, shell, or metal items. The aggregate provides texture, color, and depth.

Divider Strips

Divider strips are made of various metals. They are used for both function and decoration.
Functional: Required spacers to keep terrazzo from cracking based on cement slab movement.
Decorative: Provide separation between terrazzo sections to create design.

Top Finish

The top finish is a sealer or method of finishing terrazzo that provides varying degrees of durability, shine, and color. Terrazzo can be finished with a variety of surface finishing systems that process the surface mechanically and/or chemically.

Epoxy Terrazzo or Cement Terrazzo: What’s the difference?

Epoxy Terrazzo or Cement Terrazzo: What's the difference?

Epoxy Terrazzo or Cement Terrazzo:

What's the difference?

Recently, we’ve noticed one repeating question from designers: What’s the difference between Epoxy Terrazzo and Cement Terrazzo? Knowing that these are two great choices, we’re going to answer that burning question and provide reasons why you might choose one over the other.

Terrazzo is one of the oldest and most versatile sustainable flooring options. It is defined as a composite material poured in place or precast, consisting of marble chips and/or other aggregates combined within a binder material, which is ground and polished to a beautiful finish. Terrazzo today covers a limitless array of colors, and is known for being durable, sustainable, and flexible enough to accommodate designs from very simple and classic to extremely intricate and complex. From the royal palaces and serene bath houses of ancient times to today’s international airports, hospitals, and schools, terrazzo is a flooring canvas with infinite possibilities.

Epoxy Terrazzo Muny

Epoxy Terrazzo uses an epoxy matrix to bind the aggregates and is one of the best thin-set systems. Because this system uses a resin composite, it has a rise of only 3/8″ above the concrete slab, which means it’s also lighter than other terrazzo systems. Other great benefits include the vast array of color and pattern possibilities, durability, and chemical resistance.

StJohnsHS-SandCushion_400

Cement Terrazzo uses a cement matrix and describes multiple terrazzo systems including sand cushion, bonded, monolithic, polyacrylate, and rustic. These floors use a cement-based mix with the aggregate (chips) to form the terrazzo top. They are often thicker and heavier than an epoxy system. Also, although they offer a wide color palette, choices are slightly less than epoxy terrazzo, but create beautiful earthy tones and some can be used outdoors.

Why would I choose one over the other? If you…
– want bright, brilliant, limitless colors, use epoxy terrazzo
– want a thin-set floor, use epoxy terrazzo
– want a chemical-resistant floor, use epoxy terrazzo
– want to match or duplicate a classic space, use cement terrazzo
– are concerned with moisture vapor transmission, use cement terrazzo
– want terrazzo outdoors, use rustic terrazzo (cement)
– want a beautiful, resilient, easy-to-maintain floor, use terrazzo.

Three Tips for Project Success

Terrazzo design and installation

Terrazzo flooring presents a unique blend of aesthetic choices, functional considerations, and practical applications. Designers and architects who find the near perfect blend in creating a beautiful and functional floor keep these three things in mind during a project.


Coordinate the concrete.
Pulling together a meeting between the general contractor and the terrazzo and concrete contractors will help avoid unpleasant surprises with the concrete substrate and the placement of strips in your design. To cut down on unnecessary disruption to the floor process, the design, engineering, and concrete teams need to work together to properly coordinate the pattern with substrate joints.

Understand floor sealers and finishes. Contractors often have a preferred sealer they use, and owners generally have a finish in mind. Learn how the contractor finishes a floor and get everyone on the same page.

Terrazzo Tales: Floors that tell stories

Frazier Arms Museum 040_EDITED

Terrazzo Tales

Floors that tell stories

Terrazzo tells stories. With the rich color selection and freedom of design, terrazzo lets you create visual narratives that last through time.

This can be seen in the design for Frazier History Museum in Louisville, Kentucky. The museum, located in the city’s Museum Row, has a terrazzo flooring that features a map of the Midwest, weaving together the story of colonial America.

The design for the Richard and Barbara Silverman Hall for Molecular Therapeutics and Diagnostics takes the storytelling capabilities of terrazzo to new heights. The building was named after the legendary Northwestern University professor and developer of the Lyrica drug. To pay homage to Silverman’s creation, the terrazzo flooring features the periodic table, single-strand helices, and the molecular makeup of Lyrica.

Terrazzo can do more than simply make an eye-catching floor. It can enlighten visitors to the history of a building, honor a structure’s legacy, and carry its narrative long into the future.

Wayfinding: Designs that Guide

Wayfinding

Designs that Guide

Wayfinding systems guide people—they provide a visual experience to make complex spaces easier to navigate.

Terrazzo is especially suited for helping patients orient to large healthcare facilities, students navigate from one classroom to another, and travelers find their way in airports.

Adventist Cancer Institute is a case in point. Its poured in place terrazzo floor features a “compass of meaning” and “ribbons of hope” mentioned in the Institute’s mission statement.

“The colors of the ribbons correspond with the colors of the points on the compass, which represent peace, hope, faith, and love,” said Abby Weilmuenster, senior interior designer at Earl Swensson Associates. “And while they’re decorative, they’re also wayfinding (guides) for visitors and patients.”

The design at the Nicholas Conservatory & Gardens drew inspiration from the winding Rock River. Designer and artist Linda Beaumont describes how the design brings each visitor on a journey. “The composition of the entire floor suggests water, with additional sinuous lines of river currents adding color and rhythm. The bits and pieces of glass bring a presence of the movement of the river, swirling and pulling all the different shapes through the Conservatory lobby, and into the magical world of exotic plants seen in the distance.”

Terrazzo “takes your design factor to another level,” says Kenny Stanfield, partner at Sherman Carter Barnhart, architects for Brooks Elementary. With the design freedom and vast color palette of terrazzo, designers and architects can create wayfinding to direct wherever they want visitors to go.
