TL;DR
Edge restraint is the rigid perimeter — staked plastic or aluminum channel, a concrete toe, or set curbing — that locks the outer course of a paver installation in place so units cannot creep outward under traffic. Without it, joints open, bedding sand migrates, and the field loosens from the border in.
What it means
Edge restraint is the rigid perimeter — staked plastic or aluminum channel, a concrete toe, or set curbing — that locks the outer course of a paver installation in place so units cannot creep outward under traffic. Without it, joints open, bedding sand migrates, and the field loosens from the border in. ICPI guidelines treat it as mandatory; the spiral nails or stakes pin it into the compacted base beyond the paver edge, hidden below turf or mulch.
