A paver patio is really four things stacked up: compacted subgrade, a compacted gravel base, a thin bedding layer, and then the pavers. Only the top one is decorative. The other three are the job.
The base is where corners get cut, because nobody photographs it. Too thin, or dumped in one deep lift instead of compacted in shallow layers, and it keeps settling for years under foot traffic and rain. Then there is edge restraint: without something holding the perimeter, the outside row creeps outward, the joints open, and the field starts to wander. Patios almost always fail from the edge inward.
Joint sand is the last piece. Swept in, vibrated down and topped up, it locks the pavers against each other so the surface behaves like one plane instead of a few hundred loose pieces. Skip it and every paver is on its own.
The upside of doing all of this properly is that a paver surface is repairable in a way concrete is not — lift the affected pavers, fix the base underneath, put the same pavers back. Nothing has to be poured again.
