The Department of Chemistry at the University of Alberta provides an outstanding environment for studies in chemistry and is among the top three in the country. The department is one of the best equipped and best funded in North America and has a faculty renowned internationally for its excellence in teaching and research. The scope of work for this project was a design build and included to fully abate, deconstruct and modernize the chemistry lab space and floor finishes on levels 1 & 2 of the Chemistry West Building. The areas included new chemical research laboratory facilities as well as administrative office and break away spaces. The remodeled spaces will be highlighted as a laboratory modernization showcase for the University of Alberta Chemistry and other departments.
Although this project incorporated Mapei self leveler for the installation of the Tarkett Flooring, Johnsonite base and Armstrong VCT that all looked excellent when completed, the unique aspect of this project came into play with the Ardex PCT . The building itself is 70 years old and throughout its existence had seen many renovations and additions. The existing elevations of the concrete and existing poured toppings made it a nightmare for a traditional installation. The Architect then came across Ardex PCT and decided that with the technical advice from Ardex and installation expertise of Antex & LME partner the 15,000 square feet of labs on two floors would receive the PCT. The catch was that the Architect and end user wanted a deep grind terrazzo looking floor with a Matt finish. All areas required shot blasting as well as epoxy poured into map cracking throughout the floor surface. Afterwards we applied EP2000 with a sand broadcast for crack isolation and moisture mitigation. Following the prep of the shot blasted sub straight, our zinc strip was placed on the floor into panels that had to be lasered into place as the elevations were all different throughout the building. After the strip was placed the real fun began. While this work was ongoing we were still in the design stage with the architect. We made different samples with different aggregates to ultimately achieve a finish that was chosen. The aggregate that was chosen was from quarry in Winnipeg Manitoba. We then ordered the aggregates for delivery to Edmonton Alberta. 46 Tons of material arrived at our office. At this point we transferred the mountain of aggregates into 40lb sacks to deliver to the building. The mixing of the aggregates to PCT was one 40 pound sack to one bag of PCT. In the end the floor thickness varied from 3/8" to 1". We then proceeded to grind, grout and seal the floor with a non slip urethane sealer to the end users requirements satisfaction.
