PENETRON Specialty Products Flattens Financial Agency Floors
Transforming highly distressed concrete floors at the Alberta Treasury Board & Finance in Calgary, Canada, called for a solution from PENETRON Specialty Products (PSP), as well as paying close attention to the details. According to the general contractor, the results were impressive.
A key provincial government agency, the Alberta Treasury Board & Finance is responsible for economic analysis, budget planning, and managing province government spending. It recently renovated its Southern Alberta Headquarters in Calgary. A main part of the project was the repair and upgrade of over 25,000 square feet of distressed concrete subfloor.

Meeting Stringent Specs
The flooring challenge was to repair the existing building’s distressed concrete subfloor to produce a smooth, hard surface that met client specifications. Delnor Construction, the general contractor for the project, commissioned iSO Canada, a PENETRON Specialty Products trained and qualified contractor and flooring installer, to install the floor in the Alberta Treasury Board building. PENETRON Specialty Products Canada was also asked to provide the resources, technical support and products to meet the stringent floor requirements.
“This project was carried out to ensure compliance with our strict installation guidelines. Notable parts of the project included rehabilitating all active surface cracks and tapering the existing high areas,” added Frank McGuiness, President of PENETRON Specialty Products Canada. “We then applied PRIMER STX 100, a non-porous primer, and pumped in and placed the LEVELINE 15 self-leveling, self-hydrating underlayment as the last step before laying down the final flooring surface – in this case, interface carpet tiles.”
How It Was Done
Initially, the entire 25,000 square feet of subfloor were surveyed to determine the deviance from the specified flat surface tolerance of 1/8” in 10 feet. The most difficult step was to mechanically scarify the floor around the building columns, which was 1” too high. All cracks in the concrete were prepared and filled withPENETRON RENEW CRand an acrylic additive before PRIMER STX 100 was applied. Finally, the LEVELINE 15 self-leveling underlayment was pumped in and placed across the entire surface.
The result was a hard (5,500 psi), smooth and flat (tolerance: 1/8” in 10 feet) floor that met the carpet flooring manufacturer’s requirements for a 10-year performance warranty. Thanks to the rapid drying, early strength and self-hydrating properties of LEVELINE 15, the general contractor was ready to start interior construction the day after the installation.
“All of the client’s expectations were met and exceeded,” summarizes McGuiness. “In fact, Delnor Construction said the subfloor remedy provided was one of the best self-leveling jobs they had ever seen – and they would gladly use the product again on any other projects requiring this scope of work!”
