Tire depressions are one of the most common issues homeowners experience with interlock driveways. While it may appear that the pavers themselves are failing under the weight of vehicles, the real cause of these depressions is almost always related to the base beneath the pavers, rather than the stones on the surface.

Interlock systems are designed to distribute weight evenly across the entire surface. However, if the base material underneath the pavers was not installed or compacted properly, it can gradually begin to shift or settle over time. This is especially noticeable in areas where vehicles consistently park or drive over the same spot, creating repeated pressure on the same section of the driveway. Without a strong, properly compacted base to support the load, the material beneath the pavers can compress, causing the stones above to sink and create visible tire depressions.

Another contributing factor can be water infiltration. When joint sand deteriorates or washes out, moisture can enter the system and weaken the base material. Over time, this moisture combined with vehicle weight and freeze–thaw cycles can accelerate the settling process, leading to deeper depressions in the driveway.

The key to properly fixing tire depressions is to address the issue beneath the surface. Simply lifting and resetting the pavers without correcting the base will usually result in the problem returning. A proper repair involves carefully removing the affected pavers, rebuilding or regrading the base material, ensuring proper compaction, and then reinstalling the pavers so the surface is restored to its correct level.

Working with experienced specialists such as Seal-It Group ensures that tire depressions are repaired by correcting the underlying cause rather than applying a temporary surface fix. By properly rebuilding and stabilizing the base, the driveway can once again support vehicle weight while maintaining a smooth, level appearance for years to come.
