Raised Lawn Edge

A lawn is slightly raised (typically about 50mm, or so) above the level of an adjoining area, such as a tarmac or gravel path. The top of the lawn's rootzone around its perimeter would be exposed if there was no raised edge protecting it down towards the top of the surrounding (lower) area. A wooden or heavy-duty plastic edging strip, a brick or smooth edging stone, would typically be used as the edging material.
