Abstract: An expanding grass or weed inhibitor around a growing tree or shrub trunk with a series of overlapping, semi-circular wings (16) attached to the base (10), rotating via multiple pivot bolts (18). With an expanding trunk (14) diameter, the pressure of the trunk forces the semi-circular winds to move away from the trunk. Due to the overlapping of the semi-circular wings, their mutually-applied pressure blocks sturdier grass or weeds from uplifting the wings (16) or permeating the base (10). Along the perimeter of the base (10), a barrier wall (12) prevents the semi-circular wings from rotating too far respective to the trunk (14). For the purpose of mounting, base (10) pivots via a pivot bolt (18) while opening along slit at pivot side of base (26). On the opposite side of the base (10), slit at opening side of base (24) opens to account for a wide range of trunk diameters. To secure the base (10), lockable bolt (20) transects a hole connecting to lockable bolt (22).

Abstract: A flexible, molded, polymeric grid is embedded in a predominantly concrete mat comprising a concrete slab having relatively thicker portions defining blocks connected by relatively thinner portions, along which the concrete slab is breakable. The flexible grid has two longitudinal edges, two transverse edges, longitudinally extending members, and transversely extending members, where the longitudinally and transversely extending members connect the blocks to one another when the concrete slab is broken along the relatively thinner portions.
