How Long Does Interlock Last? What to Expect from Your Investment

When professionally installed, interlock is one of the most durable and long-lasting exterior materials available. But how long will it really last—and what kind of maintenance should you expect?

The Average Lifespan of Interlock

With proper installation and light maintenance, interlock can last 25–30 years or more. Unlike poured concrete or asphalt, individual pavers can be lifted and re-leveled if necessary, giving you a lot of flexibility and longevity.

What Makes Interlock Last Longer?

• A solid base – Proper excavation, geotextile fabric, and compacted granular base are essential.

• Correct slope and drainage – Prevents pooling water and erosion underneath the surface.

• Edge restraints – Keeps the perimeter tight and reduces shifting.

  
  

Signs It’s Time for Repair or Refresh

• Wide gaps between pavers

• Fading colour or worn texture
