All projects, regardless of their use, need to be restrained. If pavers are not restrained they will slowly “creep” into the softer surrounding materials and large gaps between the pavers will appear around the perimeter of the area.
Do you really need paver edging?
Edging is a crucial part of any paver installation. Without it, your pavers will be much more likely to spread and sink over time. ... Unless your pavers are installed with the edges touching another solid surface (a curb, driveway edge or a wall), you should have edging installed along the whole perimeter.
How do I keep my pavers from moving in my driveway?
To ensure the pavers stay in place, it's important to seal them around the edges. Pour some sand over them and move it around with a push broom. The sand should fill the spaces between the pavers. Wet the sand a bit then repeat the process until all the gaps are completely full before sweeping away all the excess sand.
