Will the colour of my interlock pavers fade over time in Ottawa's sun and salt exposure?

Yes, interlock pavers in Ottawa will experience some colour change over time, but the degree depends on the paver type, colour choice, and maintenance. Understanding what to expect helps you make a choice you'll still be happy with a decade from now.

What Causes Colour Change

Three main factors affect paver colour in Ottawa:

• UV exposure: Ottawa gets roughly 2,000 hours of sunshine annually, and summer UV intensity fades surface pigments. Darker colours (charcoal, slate, dark brown) show fading more noticeably than earth tones and lighter shades.

• Road salt and de-icers: Ottawa roads are heavily salted from November through April, and salt tracked onto your driveway by vehicles and boots creates a white residue called efflorescence. This isn't fading — it's mineral deposits rising to the surface — but it makes pavers look washed out, especially on darker colours.

• Freeze-thaw surface wear: Over many winters, the top surface of pavers gradually wears from ice scraping, shovelling, and plow contact, exposing the aggregate underneath. The aggregate colour may differ from the surface pigment.

• Through-coloured pavers (colour mixed throughout the full thickness) retain their appearance far better than surface-coloured pavers. Even as the surface wears, the colour underneath matches. Brands like Techo-Bloc and Unilock offer through-colour options at a premium of roughly $1 to $3 per square foot more.

• Surface-coloured or coated pavers look stunning at installation but can show noticeable wear patterns in high-traffic areas within 5 to 8 years. The tire tracks on your driveway will gradually appear lighter than the untravelled edges.

• Tumbled pavers (with a distressed, aged look) are more forgiving of colour change because the uneven surface masks wear patterns. These are popular in Ottawa's older neighbourhoods like Westboro, the Glebe, and Old Ottawa South where homeowners want a heritage aesthetic.

Applying a paver sealer enhances colour and provides UV protection, similar to sealing natural stone. A quality solvent-based or water-based sealer costs $1.50 to $3.00 per square foot to apply professionally and lasts 3 to 5 years before reapplication. Sealers also make efflorescence easier to clean and help protect polymeric sand joints. However, sealed pavers can become slippery when wet or icy — an important consideration in Ottawa. Look for sealers rated as slip-resistant if your driveway has any slope.

Choosing Colours That Age Well in Ottawa

Based on how Ottawa driveways look after 10+ years, earth tones — sandstone, tan, natural grey, and subtle brown blends — hold up best visually. Very dark charcoal shows salt staining and wear most dramatically. Multi-colour blends (pavers with 3 to 4 colour variations) also age gracefully because fading and wear blend into the natural variation.
