Why pavers sink, and what stops it
A paver surface is only as good as the base under it. On a driveway that means a compacted aggregate base built thick enough for the vehicle load, compacted in layers rather than dumped and leveled, then a screeded bedding course the pavers sit in. Skip the compaction or run the base too thin and the field settles into ruts and low spots within a couple of seasons.
The other half is edge restraint. Pavers are not glued down, so the field has to be locked at every open edge or the outer pavers creep outward, the joints open, and the whole surface loosens. We restrain the edges and lock the joints with sand, which is what keeps a paver surface tight and flat for the long haul.
