Abstract:
1. An edge restraint assembly for a water permeable pavement system having a loose water permeable base onto which has laid a porous material layer, comprising: a unitary member comprised of a first flat plate-like member of finite length and width configured to lie flat on an upper surface of the base and a second flat plate-like member also of a finite length extending coextensively with said length of said first plate-like member and a width oriented in a plane perpendicular to a plane of said first flat plate-like member and being connected intermediate the lateral edges thereof to one end of said first plate-like member to form a T-shape, a first portion of said second plate-like member that extends in a first direction from said first plate-like member being configured to restrain horizontal movement of the pavement system oriented on said upwardly facing surface of the base and on the porous material layer, a second portion of said second plate-like member being configured to extend in a second direction opposite said first direction and into the base to anchor said unitary member thereto; and wherein said edge restraint assembly includes a further plate-like member oriented initially either vertically above or vertically below said first plate-like member and plural fastening members for fastening said first plate-like member to said further plate-like member to draw said first plate-like member and said further plate-like member toward each other to clamp the porous material layer therebetween to thereby fixedly orient said edging strip relative to the porous material layer and the landscape surface on which said edging strip has been placed.
