- Overview: A low-cost option typically used for informal or rural sidewalks.
- Pros: Affordable, quick to install, good drainage.
- Cons: Requires frequent replenishment, less accessible for strollers and wheelchairs.
- Cost: $1–$3 per square foot.
7. Recycled Materials (Rubber, Crushed Glass, Reclaimed Concrete)
- Overview: Eco-friendly choices growing in popularity for sustainable projects.
- Pros: Reduces waste, good shock absorption, unique appearance.
- Cons: Limited availability, may not be as durable as traditional materials.
- Cost: $5–$15 per square foot.
Factors to Consider When Choosing Sidewalk Material
- Climate Conditions – Freeze-thaw cycles can cause cracking in concrete and asphalt.
- Traffic Load – High foot traffic areas need durable options like concrete or stone.
- Aesthetics – For decorative or historic areas, brick and natural stone are popular.
- Budget – Asphalt and gravel are economical, while stone and brick are premium.
- Maintenance Requirements – Pavers are easier to repair, while gravel requires frequent replenishment.
- Accessibility – Smooth surfaces like concrete ensure ADA compliance.
Maintenance of Sidewalk Materials
- Concrete: Seal every 3–5 years to prevent cracking.
- Asphalt: Reseal every 2–3 years.
- Brick: Relevel and replace damaged bricks as needed.
- Stone: Clean regularly; reseal for longevity.
- Pavers: Seal joints and reset uneven pieces.
- Gravel: Refill and compact periodically.
Cost Comparison of Sidewalk Materials
