Automobiles Guy Beaudoin Showroom
The Automobiles Guy Beaudoin dealership was starting a complete remodel and expansion of their current showroom floor and auto parts department. New and existing concrete slabs were in juxtaposition. The showroom subfloor had an epoxy coating that could not be mechanically removed, due to concerns of dust affecting the remaining open areas of the dealership. Though flooring installation products had not yet been selected, the demand for a single source manufacturer that could meet strict requirements, such as true uncoupling to overcome the concrete slab issues, was of the highest concern. A full system warranty for all manufactured products was also required.
Click Bond’s factory in Watertown, CT was about to undertake a 4,600 - sq. ft. flooring remodel. Employee productivity could not be impeded due to the flooring work, so minimalizing worker interference was extremely important. Total replacement of the existing floor was not cost prohibited so finding a solution that could utilize the existing subfloor would be needed.
George Lawrence House
Built in 1891, the George Lawrence House underwent a full renovation starting in 2015 to bring the original
historic décor back to life. Using extremely rare and expensive tiles from Italy and across Europe, ARDEX Tile and
Stone Installation Systems were selected solely for the setting of over 2,400 square feet of marble flooring,
walls and shower tile throughout the home. Working on a 125 year old original structure, lacking heat during
the cold winter months in Galesburg, IL proved challenging.
Pacific Rim Charter School
Academy of the Pacific Rim Charter Public School needed to open the 2017-2018 school year with renovations to the main entrance hall completed. The existing subfloor was gypsum-based with a high gloss finish and was cracked throughout the entire 3,800 sq. ft. floor. Budgetary and time constraints required a solution that would finish the job within 2 weeks, while providing a complete system warranty.
Sani Sport Club
Prosol Distribution and Tapis Leblanc reached out to ARDEX
Sales Professional Eric Morissette for recommendations on
a fast track solution for the Sani Sport Club’s ceramic tile
renovation of the main lobby and reception areas.
A 260 square foot basement floor in a renovation was specified to receive a porcelain tile floor. The concrete substrate contained an unknown coating that would typically require mechanical removal and significant additional costs.
