The answer to 'why is my paver bare spots' is that there are several common causes, including improper installation, wear and tear over time, and damage from heavy foot traffic or equipment. Bare spots on pavers can be caused by the pavers becoming dislodged, settling unevenly, or the sand or gravel base shifting or eroding.
Some common symptoms of bare paver spots include uneven surfaces, weeds growing between the pavers, and the pavers feeling loose or unstable. To fix bare spots, you may need to re-level the pavers, replace the sand or gravel base, and potentially re-install the pavers. For larger or more complex issues, it's best to call a professional landscaping contractor who can properly diagnose and repair the problem.
