Hiring Paver Contractors and Project Questions
- How deep should a paver base be?
- A typical paver base is about 4–6 inches deep for patios and walkways, and about 8–12 inches deep for driveways or areas that will carry vehicles. The exact depth depends on soil type, drainage conditions, climate, and expected load. In most projects, the base includes compacted gravel topped with about 1 inch of bedding sand before the pavers are installed.

- Why do pavers sink or become uneven?
- Pavers usually sink or become uneven when the base beneath them was not compacted properly, the wrong base materials were used, or water has washed out the supporting layers. Poor drainage, heavy loads, soil settling, tree roots, or freeze-thaw movement can also cause pavers to shift over time. Fixing the issue often means lifting the affected pavers, correcting the base or drainage problem, and resetting them level.

- Can pavers be installed over concrete?
- Yes, pavers can often be installed over existing concrete if the slab is stable, clean, properly sloped, and free of major cracks or heaving. The project must account for drainage, edge restraints, and added height near doors, steps, or garage entries. If the concrete is badly damaged or traps water, removing it and building a proper paver base may be the better option.

- Can a paver driveway handle vehicle traffic?
- Yes, a properly built paver driveway can handle regular vehicle traffic, including cars, SUVs, and light trucks. The key is correct installation: a compacted base, suitable paver thickness, proper edge restraints, and good drainage help prevent shifting, settling, and rutting. For heavier vehicles or frequent loads, the base depth and paver type may need to be adjusted for the expected use.
