How do I plan an Ottawa paver driveway with a house-number medallion?

Planning an interlock paver driveway with a house number medallion in Ottawa requires careful coordination of base preparation, paver layout, medallion placement, and drainage design to handle our extreme freeze-thaw conditions.

The medallion placement is your starting point for the entire layout. Position it where it will be clearly visible from the street but protected from heavy vehicle traffic — typically in the center third of the driveway, closer to the house than the street. Avoid placing it directly in wheel tracks where repeated loading could cause differential settling. The medallion area needs the same robust base preparation as the rest of the driveway, but the transition between different paver thicknesses or materials requires extra attention to prevent edge cracking.

Base preparation in Ottawa demands a minimum 450mm total depth — 300mm of compacted Granular B sub-base plus 150mm of compacted Granular A base. This depth is critical because Ottawa's frost line extends 1.2 to 1.5 metres deep, and inadequate base preparation leads to heaving that will crack your medallion and displace surrounding pavers within the first winter. On Ottawa's prevalent clay soils (common in Barrhaven, Orleans, Gloucester), install geotextile fabric between the subgrade and Granular B to prevent clay migration into your base layer.

Medallion design options include contrasting paver colours in geometric patterns, natural stone inlays, or custom-cut pavers forming numbers. Concrete pavers offer the widest colour selection and precise dimensional consistency for clean number formation. Natural stone creates a premium appearance but costs significantly more and requires careful selection of freeze-thaw resistant stone types. Avoid limestone or soft sandstone — they'll spall and deteriorate under Ottawa's salt exposure and temperature cycling.

Drainage planning is absolutely critical. The driveway must slope minimum 2% toward the street or a catch basin, and the medallion area cannot create a low spot where water pools. Standing water accelerates freeze-thaw damage, washes out polymeric sand, and creates ice hazards. If your medallion design creates elevation changes, ensure positive drainage around all edges.

Installation sequencing matters significantly. Install the main field pavers first, working from a straight edge (typically the house foundation or garage door). Mark the medallion location precisely, then cut out the field pavers and install the medallion. This approach ensures the medallion fits perfectly within your established paver pattern rather than trying to work the field around a pre-installed medallion.

Ottawa-specific considerations include selecting pavers rated for severe freeze-thaw exposure (CSA A231.2 Class 1), using polymeric sand that handles temperature cycling, and planning for snow removal. Raised medallion elements can catch snowplow blades, so keep the medallion flush with surrounding pavers. Consider how salt and sand application will affect different paver colours — darker colours hide salt residue better than light colours.

Professional installation is essential for medallion driveways. The precise cutting, fitting, and elevation matching required for a quality medallion exceeds typical DIY capabilities. Expect to pay $15 to $25 per square foot installed for a standard interlock driveway with a simple medallion, with premium materials and complex designs reaching $30+ per square foot.

Maintenance planning includes reapplying polymeric sand every 3 to 5 years, relevelling any settled pavers, and protecting the medallion during snow removal. A well-planned medallion driveway in Ottawa lasts 25 to 30+ years with proper maintenance.
