A construction block is provided for use in constructing walls. The block includes a front panel, a rear panel, and at least one web connecting the front and rear panels. Each of the front and rear panels is rectangular and has a top edge surface, a bottom ed ge surface, and right and left edge surfaces. At least one web having top and bottom surface s co-extensive with the top and bottom surfaces of the front and rear panels is provided, thereby to define a top surface of the block, and a bottom surface of the rack. The top surfac e of the block is provided with a shallow rectangular ridge along its length, flanked by longitudinally extending outer support surfaces. The lower surface of the block has a shallow rectangular channel formed therein along its length, flanked by longitudinally extending flat outer foot portions corresponding in width to the outer support surfaces. The right and left edg e surfaces of the front and rear panels are profiled to interfit with one another, whereby the right front edge surface and the left rear edge surface each have a first profile, and the le ft front edge surface and the right rear edge surface each have a second profile, the first and second profiles being complementary to permit blocks to interfit end to end.
