What thickness of pavers should I use for my driveway?

For driveways in Metro Vancouver, you need 80mm (3-1/8 inch) thick pavers minimum. This is the industry standard thickness designed to handle vehicular traffic loads without cracking or chipping under the weight of cars, trucks, and delivery vehicles.

Standard 60mm pavers used for patios and walkways are not suitable for driveways. While they may initially appear to handle light vehicle traffic, the repeated loading and unloading cycles from cars parking, turning, and braking will cause 60mm pavers to crack along the edges and develop surface spalling within 1-2 years. This is especially problematic in Metro Vancouver where the persistent moisture from our 1,200mm+ annual rainfall can infiltrate hairline cracks and accelerate freeze-thaw damage during our 5-15 annual freeze-thaw cycles.

The base preparation is equally critical as paver thickness for driveway installations. Your 80mm pavers must be installed on a minimum 10-12 inch deep compacted granular base in Metro Vancouver's clay-heavy soils. This base depth increases to 14-16 inches in areas with poor drainage or high clay content like parts of Surrey, Richmond, and Delta. The base material should be 3/4-inch minus crushed rock compacted in 2-inch lifts using a plate compactor to achieve 95%+ compaction. Without this substantial base, even 80mm pavers will settle unevenly under vehicle loads, creating a wavy, unsafe driving surface.

Permeable pavers for driveways also come in 80mm thickness and are increasingly popular in Metro Vancouver as municipalities encourage stormwater management solutions. Permeable pavers allow rainwater to infiltrate through the joints into a specially designed open-graded aggregate base, reducing runoff to the municipal storm system. Some Metro Vancouver municipalities offer stormwater fee reductions for properties that install permeable paving systems.

Edge restraints are mandatory for driveway installations to prevent the pavers from spreading under vehicle loads. Heavy-duty aluminum or steel edge restraints must be installed along all unconfined edges and properly spiked into the compacted base. The transition where your paver driveway meets the municipal sidewalk or street requires careful attention to grade matching and proper edge support.

This is definitively a professional installation project. Driveway paver installation requires excavation equipment, proper base compaction with commercial-grade plate compactors, laser levels for precise grading, and experience with vehicular load calculations. A poorly installed paver driveway will develop ruts, settling, and drainage problems within the first year. Professional installation of a typical 500-800 sq ft driveway in Metro Vancouver runs $10,000-$24,000 including excavation, base preparation, 80mm pavers, edge restraints, and polymeric sand jointing.
