Many asphalt companies have experience with tar and chip paving, but not all. The process is unique enough—and not incredibly common enough—that you may have to look around for a tar and chip specialist.

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.
