Abstract
A simulated masonry module, made of blow molded plastic, has a hollow box-like body with a heavily textured front and top. Modules are pin-connected to each other at interleaving ends, which preferably comprise a slot mortise and tenon which fit closely, so that rotation about the pin is prevented. Modules may be stacked, to form assemblies simulating a masonry wall, and to form an enclosure suited to contain soil or water in a tub-like liner. Sand or other material may be put inside the modules through a rear access port, to add mass and stability. The bottom of a module has sculpting, to loosely fit and interlock with the contour of the top of a like-module, when modules are stacked, so the horizontal joint is unobtrusive. A spike, used for connecting module ends, is retained in a shaped groove on the rear of the module, to enable convenient shipment of a module and spike combination.
