Abstract: Edging members for retaining or restraining installations of pavers, landscaping, and covering materials are constructed for endwise, longitudinal assembly with one another, and to receive stakes of generally V-shaped or generally U-shaped cross section, and spikes driven at angled orientations, for securing the members, on a substrate, against lateral and upward displacement.

Abstract: A hand tool for tracing the course of a line of pavers at a distance selectively spaced therefrom, so as to facilitate the construction of uniform borders along a walkway, path, or the like, consists of a tracking head for running the tool along the installed line of pavers, a marking head for remotely replicating the course, a beam on which the heads are mounted, and a handle. The positions of the marking head and handle are longitudinally adjustable on the beam, relative to the tracking head.

Abstract: A bed-depth gauge consists of a guide member, a screed member, and means for assembling them for relative movement, for effective depth adjustment, in a vertical direction that is generally perpendicular to a bottom edge of the screed member. The guide member has a pair of arms that extend laterally, at different heights, which are used to engage and follow a fixed reference surface to thereby enable the bottom edge of the screed member to level and control the depth of both a base layer and also an overlying upper layer, comprising a bed prepared for installation of paving blocks and the like.
