The answer to 'why is my paver' is that there are several common reasons why pavers may become problematic. Some of the most frequent issues include uneven settling, cracking, and weed growth between the pavers. These problems can be caused by improper installation, soil erosion, or lack of maintenance.
If your pavers are uneven or have started to shift, it's likely due to the settling of the base material underneath. This can happen over time as the soil compacts or erodes. Cracking is often caused by heavy weight or impact on the pavers, or by freeze-thaw cycles that put stress on the material. Weed growth is a common annoyance that happens when weeds take root in the spaces between pavers.
