Gateway Arch, St. Louis, MO

The Gateway Arch National Park Museum and Visitor Center is a soaring symbol that manifests the starting point of westward expansion. The mezzanine level floor incorporates the perfect image to match the Arch’s grandeur: a map of the United States depicting the major rivers, lakes, mountain ranges, and expedition trails of westward expansion. That map was created with 4,200 square feet of epoxy terrazzo using more than 10 colors.

The renovation and expansion was intricate. The project had just about every possible element of terrazzo, including Venetian marble, more than 52,000 square feet of sand cushion terrazzo in two colors, an epoxy map, precast steps, precast base, and a poured-in-place base. There were also significant challenges: staging was tough since the park remained open during the renovation. More than one million pounds of sand had to be brought in while also removing tons of earth. And the job was in a national monument, with accompanying heavy security.

“We are all proud to have worked on a project of this magnitude,” says Paul Berra of Missouri Terrazzo. “The finished product of this beautiful, durable terrazzo floor ties together the renovated original museum section and the new entry level, mezzanine level, and museum area with a bright, long lasting, timeless terrazzo floor.”

Terrazzo Helps University Structures Connect

Terrazzo Helps University Structures Connect

Olin School of Business Expansion, St. Louis


As Washington University began revamping the flooring in the Olin School of Business, the renowned St. Louis college called in Moore Ruble Architects & Planners and Missouri Terrazzo to design and execute the job.

The 34,000-square-foot terrazzo installation was part of a large 120,000-square-foot expansion project to connect Olin School of Business with the Charles Knight Center, according to Kevin Rickman of Missouri Terrazzo.
Unlike most flooring in other academic institutions, the design for the Olin School doesn’t have large emblems or other symbols related to the school. Instead the design was kept simple so as to not distract from other elements of the space, but donor names were carved into the floor later on, Nick Naeger said. The terrazzo design overall complements the existing structure, and the project was among the most high-end of his career, he added.

“It was a subtle selection, but it helped pop a lot of the aspects in the atrium space,” Naeger said. “One of the big architectural benefits is that it appears as though it’s completely seamless.”

The flooring was used to connect the public space to more private areas in the building, Naeger said. Though the terrazzo is the university’s preferred flooring, the terrazzo flooring was a great choice for a high-traffic area, and the pattern worked well aesthetically with the stained wood panels and trim, limestone and other existing materials in the space.

“Terrazzo is a great product for areas with high circulation. Its durability is just awesome!” Naeger added. “[The new flooring] worked well with the whole high-end interior palette.”

Terrazzo Ties Together Hospital’s “Whimsical” Architecture

Terrazzo Ties Together Hospital’s “Whimsical” Architecture

How can terrazzo be installed in a busy hospital and complement its existing architectural design? Ask Kevin Rickman of Missouri Terrazzo.

Missouri Terrazzo’s major challenge on the Mercy Hospital project in St. Louis was to install at 3/8” epoxy terrazzo, in 6 colors, with multiple radius designs, in multiple phases while keeping a very busy hospital open and functioning. The 20,000-plus square-foot project was installed off and on for a three-year period.

“Scheduling and phasing were a major part of this project,” Rickman said. “Protection was a key detail as we worked around offices, elevators, escalators, and other types of floor finishes.”

Four of the colors are mixed with a combination of size and various glass and marble aggregates. They’re separated by flowing 1/8” zinc strip that were shaped and set on site. Areas of terrazzo near the chapel had to be poured-in-place in unique shapes and designs.

The stairs and stringers on a slight radius were installed along with a 12” high, 1” thick epoxy base throughout the project. Missouri Terrazzo had to be exact in its field templates in order to have 12 existing columns, which included precast caps, fit precisely.

Replacing an existing vinyl floor, terrazzo became the flooring finish of choice due to its longevity and ease of maintenance.

“The strip patterns and color changes flow throughout, encouraging the hospital’s visitor traffic flow and helping to tie together the varied whimsical architectural designs throughout the lobby area,” Rickman said. “The client was really excited about terrazzo and thought it was worth the effort of all involved to make this project a success.”

Terrazzo Quality: Worth the Wait

Terrazzo Quality: Worth the Wait

When the highly anticipated new high school in Knoxville, IL ran into scheduling conflicts and budgetary concerns, a decision was made to remove the beautifully designed terrazzo concept from the project. Because of terrazzo’s reputation for high quality, pattern options and ease of maintenance, this split-second reaction was quickly reversed, and the installation was pegged for the summer of 2015.

“Missouri Terrazzo was very pleased with the fact that the school district could have chosen another flooring type to complete the project earlier, but chose to wait a year to allow for the terrazzo installation,” Kevin Rickman, Missouri Terrazzo, said. “They knew installing terrazzo as the main centerpiece would create a beautiful and memorable entrance to the school.”
Terrazzo Quality: Worth the Wait
The school opened for classes in August 2014, meaning the terrazzo install would be completed around an already established state-of-the-art school. Protection of all existing school items such as monitors, trophy cases, and other items in the auditorium, library, and offices was key.

“Careful consideration had to be made to protect the existing finishes and equipment from damage, while installing a new 5-color terrazzo floor system,” said Rickman. “The install needed to be as if it had been there from the beginning.”

The 13,000 square feet of terrazzo begins in the school’s main entryway. A large bold blue “K” logo representing the school’s colors, lies in the center, welcoming students, faculty, staff, and visitors.
Terrazzo Quality: Worth the Wait
A four-color pattern of shades of brown, tan, and beige flows from the entryway into the cafeteria/multi-purpose area that’s used as eatery space, small group meetings and study sessions, and thru traffic. These rays of color continue down the main corridor to connect with the kitchen/serving area and seamlessly transitions to carpet to complete the library.

The warm coloring of the terrazzo complements the natural stone wainscot and columns within the cafeteria and corridor. The flooring is completed by a brown precast terrazzo wall base that allows a smooth transition between the floor and wall.

“Chosen for its aesthetic enhancements, durability, longevity, and ease of maintenance, this terrazzo floor will provide this facility with a strong foundation for years to come,” Rickman said.

Terrazzo Creates Whirlwind of School Spirit

Paducah Middle School

As powerful as a tornado, a good education has the ability to cause remarkable change. Once absorbed, knowledge is carried to places much further than where it began, elevating students to new heights. Paducah Middle School embraces its mascot and provides a wealth of inspiration right as you enter the school.

Greeting you on the floor of the main entrance spins a 24-foot Fighting Tornado, the school mascot, armed with a book and pencil, full of school spirit and ready to learn.

The Fighting Tornado logo in the terrazzo lobby floor is made complete by a surrounding compass with an arrow pointed to the high school, the students’ next stop in their education. Motivational and inspiring words framed by yellow stars put the finishing touches on the centerpiece of the school’s terrazzo flooring.

“That’s to remind the students to reach for the stars in their academic and personal lives,” said Kevin Rickman, Missouri Terrazzo.

Chosen for its longevity and durability, 3/8-inch epoxy terrazzo is featured in 20,000 square feet of the brand new, 92,000-square-foot building.

Terrazzo continues in the hallways on both the first and second floors. White epoxy and an accenting radius blue epoxy border run along the lockers. Lining the hallways are 120 1-foot blue epoxy Fighting Tornadoes, continuing the display of Paducah school spirit.

The cafeteria features a staggering brick pattern of yellow and white epoxy terrazzo in a 3-foot-by-6-foot herringbone design.

Rickman said terrazzo is especially beneficial in the cafeterias, hallways, and lobbies of middle schools due to its ease to maintain and clean.

“Whether it’s spills or foot-traffic, the wear on terrazzo is excellent,” he said. “It’s the only floor to put in.”

Terrazzo Provides a Bright Welcome That Will Never Fade

Lambert Airport
Linking America’s heartland to international crossroads, Lambert-St. Louis International Airport serves as a hub for the blending of the many different curiosities, cultures, traditions, and future possibilities of more than 12 million travelers a year. During a recent remodel, one objective was to create a brighter environment for these millions of travelers. Taking a creative approach to the update, a design competition was held for artists to submit drawings—reflecting the many different cultures that touch down in St. Louis—for the airport’s terrazzo flooring.

Artist Alicia LaChance’s “New Village,” a lively 41-color design, was chosen, and fully embraces the flexibility of the medium.

“The logo describes her interpretation of the world—all the different countries of the world that could possibly come through Lambert Airport,” said Kevin Rickman of Missouri Terrazzo, the terrazzo contractor for the renovation.

The 19,000 square feet of newly installed epoxy terrazzo is located at the security entrance to concourses C and D. As the vast majority of the floor is an off-white epoxy with a marble, glass, and mother of pearl chip design, LaChance’s bright, 400-square-foot inlay design stands out dramatically. The logo lies at the entrance to the two concourses, greeting all arriving passengers to St. Louis.

For this vivid logo design, the new terrazzo flooring was installed on top of the already existing terrazzo. Rickman said this process doesn’t differ much from a fresh terrazzo installation, as it still includes prepping the existing surface and putting in divider strips.

Working with Missouri Terrazzo, LaChance directed and selected each epoxy color for the logo, using glass, plastic, and mother of pearl chips. A color drawing with numbers that corresponded to the epoxy and aggregate colors sample sheet was then created to keep the brilliancy of the design organized. Installers poured as many of the 41 colors as they could in a day. As each individual epoxy was mixed and poured by hand, divider strips were continuously cleaned to ensure colors would not run during the next day’s pouring. Rickman said the logo is something wonderful for travelers to look at and appreciate, as a large amount of creativity and work went into the design and creation of “New Village.”

“To see that many different colors in one area, it just catches the eye,” he said. “And it won’t wear out.”

Color flexibility and sustainability make terrazzo the ideal flooring for high foot-traffic areas like Lambert-St.
Louis International Airport.

“Terrazzo won’t normally wear out. You can put one floor in and it can last up to 80 to 100 years,” Rickman said. “Terrazzo is just a great product.”

The Airport Authority at Lambert agrees, as it contracted Missouri Terrazzo to continue with an additional 50,000-square-foot terrazzo remodel at the ticketing level.
