TEC® System Helps Revive Detroit’s Cobo Convention Center
Surface Preparation and Tile-Setting Products Provide Elegant Aesthetic and Strong Performance in Riverfront Atrium
Since its opening in 1960, Cobo Center has drawn visitors to the banks of the Detroit River for the nation’s premier auto shows, political conventions and an endless variety of other events. Its renovation aims to reinvigorate the convention center and the entire region, in part by establishing connections with downtown Detroit and the Detroit River.
With a panoramic view of the river through floor-to-ceiling glass windows, Cobo’s three-story atrium creates a physical link between the convention center’s dramatic new riverfront entrance and main concourse. The 250-by-65-foot atrium can host 600 people seated for a meal, 1,000 seated theater-style and 1,200 for receptions. Large-format tiles, installed with a wide range of TEC® products, span the atrium’s floor. Installers also used TEC®products to place 1-by-2-foot floor tiles and 1-by-3 meter large thin wall panels in nearby restrooms.
Cobo hosts two of the Motor City’s most iconic annual events: the North American International Auto Show, one of the largest auto shows on the continent, and Autorama, a large showcase of custom cars. With consideration for these events, the TEC® system underwent testing before installation to determine how it would perform under heavy wheel loads.
"In the atrium, we did a mockup using TEC® products to set large-format porcelain tiles,” says Bob Michielutti, owner of Michielutti Bros, Inc., the tile contractor for the space. “After 30 days, heavy construction vehicles, including forklifts and scissor lifts, were driven over the floor. It didn't budge. From then on, the building owner and architect shared our confidence in the TEC® system and the warranty TEC® was going to provide.”
Although today, 2-foot-by-4-
TEC® Multipurpose Primer and HydraFlex™ Waterproofing Crack Isolation Membrane were used both in the restrooms and in the atrium. In the restrooms, HydraFlex™ provides waterproofing, while in the atrium, crack isolation was most important.
“In Michigan, the ground is always moving. It’s freezing and thawing, which can cause the substrate to expand and contract. That’s why we use HydraFlex™,”
HydraFlex™ may help prevent future cracking in the substrate, but installers also needed to address its existing problems. An even substrate was crucial for successful installation of the large thin tile used in the atrium. However, when installers began work, they found an uneven subfloor and turned to TEC® Fast-Set Deep Patch to help correct the problem.
“The substrate was very challenging. It was up to 1/4“ higher and 2” lower than the level plane, and we used Fast-Set Deep Patch to level it. Fast-Set Deep Patch is very strong, and it sets fast. Now we have a flat floor – you can roll a quarter across it,” says Shumard.
According to Bob Michielutti, TEC® Ultimate Large Tile Mortar also contributes to the floor’s uniform surface. Despite the fact that installers used two different colors of tile with slightly different thicknesses in the atrium, TEC® Ultimate Large Tile Mortar helped them account for that difference and achieve a more consistent floor. It also delivers its non-sag characteristics to the large, thin panels installed on the walls of the convention center’s restrooms, and was used to install tile on their floors as well.
In Cobo’s atrium and restrooms, another product in the TEC® roster, TEC® Power Grout® Ultimate Performance Grout, provides stain-, crack- and efflorescence-
TEC® products will also be used for the installation of the ceramic wall tile in the convention center’s kitchen.
The Cobo Center atrium was completed in late 2013. The convention center’s renovation began in September of 2009 and is expected to be completed by the end of 2014. Other aspects of the renovation include a 40,000-square-
