What is the installed price for a polyurea coating on an Ottawa loading dock?

Polyurea coating for an Ottawa loading dock will typically cost between $12 and $22 per square foot installed, with most commercial projects falling in the $15 to $18 range depending on the specific system requirements and floor preparation needs.

Loading docks present unique challenges that make polyurea an excellent choice for Ottawa's harsh climate. These areas endure constant forklift traffic, chemical spills from hydraulic fluids and cleaning products, freeze-thaw cycles from open dock doors, and road salt tracked in by delivery trucks. Polyurea's exceptional chemical resistance and rapid cure time make it ideal for minimizing business downtime — most systems allow foot traffic in 2 to 4 hours and full vehicle traffic within 24 hours.

The coating system for a loading dock typically requires a 100% solids polyurea at 15 to 30 mils thickness, significantly thicker than residential applications. This heavy-duty system provides superior impact resistance and chemical protection. Surface preparation is critical and usually involves diamond grinding or shot blasting to achieve the proper concrete surface profile, adding $3 to $6 per square foot to the total cost. Crack repair and joint sealing are essential given Ottawa's extreme freeze-thaw cycles, potentially adding another $2 to $4 per square foot depending on existing damage.

Ottawa's climate creates a narrow application window for unheated loading docks. Polyurea can be applied at lower temperatures than epoxy — some formulations work down to -10°C — but most loading dock applications should be scheduled between April and November when ambient temperatures consistently stay above 10°C. The concrete substrate temperature is equally important and must be at least 5°C above the dew point to prevent moisture issues during curing.

This type of commercial flooring work requires proper permits and WSIB coverage. The City of Ottawa may require permits for commercial floor modifications, especially if the work involves changes to fire-rated assemblies or structural elements. Always confirm permit requirements by calling 3-1-1 before starting the project.
