Installing Fiber Optic Lighting in Stamped Concrete

When The Cordish Cos., out of Baltimore, Md., set out to build the Power & Light entertainment district in Kansas City, Mo., the company envisioned a flashy fiber optics in a common area central to where most of the nightclubs would be situated.

“They wanted something over the top,” says Mike Denny. Denny is president of Artistic Concrete Surfaces, a company in Olathe, Kan.. The homeowners hired his company to pour, color and stamp the concrete area so it would look like wooden planks. “We were supposed to spell out ‘Live’ on the floor in lights. However, after we got through the whole process of how we were going to do it, the top dog pulled the project at the last second.” ACS still did the floor, just without the glitter.

Disappointed, Denny found himself telling a residential client about this turn of events. He had been really looking forward to the job. This was because even though he had incorporated fiber optics into concrete countertops, he had never attempted to put the lighting into a slab. It wasn’t Denny’s original intention to entice the couple, but he sold them. “Once they heard about it, they had to have it,” Denny says about homeowners Ann and Mike Bilovesky. “They thought fiber optics in a patio sounded really cool.”

In the fall of 2010, Denny brought over a 10-man crew. Their goal was to create an outdoor living area that would be expansive. The space would have no set boundaries. It would also be easy to keep up with few or no maintenance materials. It took the company, which specializes in stamped and polished concrete and concrete overlays, six weeks to finish the approximately 1,200-square-foot job in Overland Park, Kan. The project included extensive landscaping, a natural stone fireplace, a concrete and stone water bubbler, lighted steps leading into the house, and a stamped concrete patio that incorporated boulders and fiber-optic lighting into the design.

The job’s biggest challenge was figuring out a way to texture the surface without burying or breaking the fibers, Denny says. “The customer was intent on having stamped concrete, so not stamping wasn’t an option.”

Denny’s crew first poured a 2-inch-thick slab to serve as the base of the patio and then drilled 600 1-inch-deep holes into it. Next the crew drove 3-inch nails into the holes, leaving about 2 inches of each nail above the finished concrete, and attached the fibers to each with tie wire.

Once they securely attached the wires, they poured integrally colored concrete to the level of the tops of the nails. The concrete contained a retarder. This gave them plenty of time to finish and stamp it with very flexible polyurethane seamless skins from Matcrete.

“We had to cut the stamps into 1-by-1 foot pieces and go around the wires by hand to get the surface stamped without bending the wires back into the surface,” Denny explains. If they missed, the bent wire would leave a little line that had to be repaired.

“I guess there were three or four fiber optics per square foot and we had to bend each one of those in order to get in between the wires,” he says.

A hot knife is used to cut the ends of the fiber optic lights after the colored stamped concrete has cured.

The fibers were installed in a 7-by-25-foot ribbon of concrete that flowed through a 20-by-25-foot patio section. Needless to say, the process took a long time. Besides using a retarder to slow the set, the crew picked a cool day with no wind to tackle this part of the project.

After placing and then stamping the colored concrete, the crew used a hot knife to cut off the tops of the wires. This allowed the wires to stay flush with the surface. The crew then went over the entire surface with a semigloss decorative acrylic sealer.

Just like Christmas tree lights

The crew funneled the fiber-optic strands from all 600 points of light into several 1-inch-thick cables. These cables snaked underneath the patio. Each cable connected to one of two ports. They situated these ports in a watertight compartment hidden in the back of the stone fireplace. The compartment also houses a light box. There, a color wheel and two LED light bulbs produce the light for the reflective fiber-optic display. Just like Christmas tree lights, you can program the lighting to change colors at various speeds. You can also set them as just one color, including white. Additionally, you can turn them off all together. There are also about 10 different colors from which to choose.

Turns out the Bilovesky project turned the heads of more than just the neighbors. It won the 2011 Excellence in Concrete Award from the Concrete Promotional Group. Additionally, the company received an Honorable Mention for Top Decorative Concrete Projects in 2011 from Concrete Construction magazine. And, in the 2011 receieved Residential Project of the Year from the Kansas Chapter of the American Concrete Institute.

Outdoor living spaces puts ACS on the map

Denny says his company is well-known in the area for the outdoor living spaces it creates. It added both landscaping and CAD design to its roster of services to diversify when construction was off in 2009, he says.

To avoid burying or breaking the fiber optics when installing the concrete, the crew from Artistic Concrete Surfaces, Olathe, Kan., attached the fibers to nails with tie wire first. They then carefully placed and stamped concrete around the nails.

“With our CAD design software, we’re able to walk our clients through their projects. This will give them a great idea of what the finished product would look like,” Denny says. It was the walk-through capability, he adds, that really cinched the fiber optics part of the Bilovesky deal.

Today, with a full-time designer on staff, Artistic Concrete Surfaces prides itself on being a design-build contractor that can help transform visions into tangible realities. “We went from being a concrete contractor to a full-service, start-to-finish outdoor contractor. We deal with landscaping and anything else a client might want in an outdoor living area,” Denny says.

Adding the extra services was “a huge stepping stone for us,” he says. “We went from earning $1 million to $3 million in a matter of a year and a half. People really appreciate dealing with one contractor who gets finish the job on time and on budget. Our referrals are endless.”

Artistic Concrete Surfaces added landscaping to its roster of services in 2009. The company used both spruce and river birch trees combined with a natural stone riverbed to solve water runoff issues in the Bilovesky backyard.
