#2- Uneven and Loose Pavers
Uneven pavers are really one of the most dangerous patio problems. Even a small height difference can cause trip and falls for guests and hazards, especially in the evening hours. You do not want to have to navigate around a certain area of your patio because the pavers are so uneven you stub a toe or fall.
Pavers can become loose if they are installed too far apart or incorrectly in general. Uneven gaps can also become a tripping hazard. Often times this issue is seen near the perimeter of your patio, especially if a proper edge restraint is not installed. It may look like the edge is leaning or tipping and pavers are about to topple over into the grass. In extreme cases, if you step right on the outer paver, it will fall, roll, or sink. There are several great options for edge restraint PVC, aluminum, or metal depending on the specific application.
All of these issues can arise as a result of improperly installed pavers. Because of this, the repair process is usually quite extensive. Uneven and loose pavers typically point to an issue with the base installation. A proper base is key for supporting the weight of the pavers themselves and whatever else is then put on the pavers—furniture, grills, or even vehicles.
