Green roof edging and restraint system

Abstract

An edging system for green roofing applications defines the margin between grow medium zones and vegetative free zones. An edge and restraint system comprises a edging structure having a substantially upright section having a height and a base section extending laterally from a the middle or lower end of the upright section on at least one lateral side thereof. The base section extends substantially perpendicularly from the upright section. The upright section and base sections may or may not include openings therethrough to allow drainage of water and the like. The upper end of the upright section is adapted to allow a restrainer piece to be releasably secured thereto in snap fit engagement. An edge of a water permeable fabric, which extends between a grow medium and drainage board upon which the grow medium is contained, is essentially secured in place at one end thereof by positioning an end portion thereof which extends from under the grow medium under the restrainer piece as it is snapped in place upon the upright section.
