Can heavy delivery trucks like concrete mixers or moving vans damage my residential driveway in Ottawa?

Yes, heavy delivery trucks can absolutely damage residential driveways in Ottawa, especially if your driveway wasn't designed for commercial vehicle loads. Most residential driveways are built for passenger vehicles and light trucks, not the concentrated axle loads from concrete mixers (up to 34,000 kg loaded), moving vans, or delivery trucks.

Asphalt driveways are particularly vulnerable because the standard residential asphalt thickness in Ottawa is typically 75-100mm total (50mm surface course over 50mm binder course). Heavy trucks create concentrated loads that can cause rutting, cracking, and permanent deformation, especially during warm weather when asphalt is softer. The damage often appears as tire track depressions, spider web cracking under the wheel paths, or edge cracking where trucks turn or back up.

Interlock driveways can handle heavy loads better due to their distributed load-bearing design, but only if the base was properly constructed. Heavy trucks on interlock with inadequate base depth (less than 450mm total granular base) can cause pavers to settle, creating permanent low spots and uneven surfaces. The edge restraints may also shift under heavy loads if not properly installed.

Concrete driveways are most resistant to heavy vehicle damage when properly reinforced, but standard residential concrete (100-125mm thick) can still crack under extreme loads, especially at joints or where the base preparation was inadequate.

Ottawa's climate makes damage worse because freeze-thaw cycles exploit any cracks or deformation created by heavy vehicles. A small crack from truck loading becomes a major failure point during winter freeze-thaw cycling. Clay soils common in Barrhaven, Orleans, and Gloucester areas compound the problem by providing less stable subgrade support.

Protect your driveway by requesting trucks stay on the street whenever possible. For concrete deliveries, have the mixer truck position at the street and use a concrete pump or wheelbarrows. For moving trucks, consider renting plywood sheets (19mm minimum) to distribute the load across a larger area. Schedule heavy deliveries during cooler weather when asphalt is firmer.

If damage occurs, document it immediately with photos and contact your contractor or insurance company. Rutting deeper than 10mm, new cracking, or settled pavers typically require professional repair ranging from $500-3,000 depending on the extent.
