Interlocking pavers offer a number of advantages over regular pavers. For instance, they’re more durable, more resistant to shifting, and easier to repair. There are also permeable options that allow for drainage. However, interlocking pavers are more often more expensive than regular pavers and are prone to growing weeds over time.

The most common causes of sunken pavers are poor base preparation and insufficient compaction. The problem could also be how your pavers were installed. If the soil beneath your patio or walkway wasn't compacted, it will pull pavers down as it settles. Additionally, using bare soil instead of making a paver bed with compacted gravel and sand can cause sinking over time. To fix sunken pavers, consider recompacting the base and addressing any drainage or erosion issues in the area.

The best way to stop your pavers from sinking is to ensure you've properly compacted the base layers. Use your paver compactor and work over the base layer several times to create the hardest possible base. If the soil and sand of your base are compact, you’ll experience less shifting and sinking.

Heated driveways cost an average of $12 to $25 per square foot. Depending on the size of your driveway, you may pay between $3,500 to $25,000 in total.
