Abstract
An edge restraint and method of use where the edge restraint has a vertical wall for retaining segmental pavement in an installation placement and a horizontal base having a plurality of teeth extending therefrom and providing discrete focused points for providing friction between the edge restraint and an installation surface to prevent horizontal movement of the edging in at least one direction with respect to the installation surface. A leading edge of the base is installed under a first surface with the wall providing a barrier between the first surface and a second surface for engaging the teeth with a third surface to prevent movement of edging in a horizontal direction away from the first surface.
