Abstract
Abstract A construction assembly comprising a plurality of individual construction units connected together. Each of the construction units comprises a pervious resin-impregnated fibrous mesh material. The walls of the construction units have a cementitious material secured to the exterior surface thereof by permeating the pervious resin-impregnated fibrous mesh material and forming an integral structure therewith.
