edge restraint
In short and in plain language
An edge restraint is the firm side edge of an area of paving or slabs.
It is usually made of kerbs, posts or steel edging.
It holds the surface and the bed below it in place. So the area does not spread at the edge.
Without a firm edge, stones can shift over time.
