- 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.
- 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.
- What is polymeric sand used for?
- Polymeric sand is used to fill the joints between pavers, bricks, or natural stone in patios, walkways, and driveways. When activated with water, it hardens to help lock pavers in place, reduce weed growth, deter insects, and limit joint washout from rain or cleaning. It is commonly used after new paver installation or during paver repair and re-sanding projects.
- 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.
