WeatherTech Company, maker of auto floor mats and other accessories, recently expanded its Bolingbrook, Ill., corporate campus by annexing existing buildings and adding new construction. The most recent expansion—to create a state-of-the-art marketing, sales and services center—combined an older building with a new addition, for more than 35,000 sq. ft. of new space.

Along with department offices, the new WeatherTech building houses the company’s video production studios, employee kitchen and exercise area that includes a climbing wall. To achieve the many needs within the building, the existing footprint required significant changes. This presented unique challenges, especially when it came time for floor preparation. WeatherTech has had a long business relationship with PCI FlorTech, which became the flooring dealer for much of the expanded campus.

The older building was stripped back to the outside four walls, which left a wide variety of existing floor surfaces that needed significant repairs. PCI FlorTech’s vice president, Tom Sheridan, noted: “Once we saw the state of the concrete floors, we knew the surface preparation was going to be very challenging. We immediately called in H.B. Fuller Construction Products, manufacturer of high-quality floor prep products, to help us choose the best system.”

After consulting with Ron Loffredo, H.B. Fuller’s technical services manager, PCI FlorTech chose TEC products to address two key issues in the floor preparation: mitigating moisture issues and leveling the varying elevations of the patchwork floor.

To start, LiquiDam Penetrating Moisture Vapor Barrier was applied to the surfaces on the first floor of the existing structure, while LiquiDam EZ Moisture Vapor Barrier was used on the new construction concrete. LiquiDam EZ allowed PCI FlorTech to eliminate applying primer in most of the new areas, according to the company.

Next, PCI FlorTech prepared to patch and level the older existing floors with TEC Multipurpose Primer followed by TEC Feather Edge Skim Coat and the new TEC Level Set 300 Self-Leveling Underlayment.

Pete Majeski, a supervisor at PCI FlorTech, stated, “TEC Feather Edge and TEC Level Set 300 did an incredible job to overcome one of the worst subfloor situations we’ve ever seen. Additionally, we had significant surface cracks from deflection of the new lightweight concrete on the second floor, and the TEC Multipurpose Primer combined with TEC Feather Edge took care of it.”

TEC Level Set 300 is a high-performance, self-leveling underlayment that creates a flat, extremely smooth and durable surface for new flooring (Centaur recycled rubber was chosen for this project). The TEC self-leveling product is walkable in just two to three hours, which helped save time in an already tight flooring schedule.

The new TEC TrowelFast Flooring Adhesive was used to adhere the rubber flooring in the high-traffic areas of the building. The adhesive’s unique formulation dries quickly, has a long open time and provides excellent resistance to moisture, according to H.B. Fuller.

When asked about WeatherTech’s response to its newest building, Sheridan explained: “The new marketing building is a showcase for WeatherTech, for both visitors and employees. With a beautiful atrium and the many amenities, David MacNeil, CEO of WeatherTech, is very proud of this project. In turn, PCI FlorTech is grateful to have the decades-long relationships with both WeatherTech and H.B. Fuller Construction Products that helped make this project a success.”

In addition, the company shared the following words about its former president, Mike O’Connell. “Mike O’Connell, president of PCI FlorTech, passed away too soon in August 2017. He was an outstanding partner to his employees, his vendors (including H.B. Fuller Construction Products) and his many customers—especially WeatherTech, where he enjoyed more than a decade-long relationship. Lauded by the flooring industry and Starnet Worldwide Commercial Flooring Partnership, where his company has been a member since 2005, Mike understood the value of integrity, honesty and friendship in business. He is missed by all.”
