In a retaining wall comprising stacked courses of concrete modules, eac h module has unitary walls including a front wall, two lateral walls, and a bottom wall, the front and lateral walls being upright. Each lateral wall has a fro nt edge adjoining the front wall, a back edge spaced from the front edge, an upright rib extending inwardly from said lateral wall, and an upright rib extending outwardly from said lateral wall, the upright ribs being spaced equally from the front wall. Each lateral wall has a provision, such as a recess opening upwardly or an opening through that lateral wall, which is adapted to receive and receives a batten so that the batten can extend through said lateral wall and which is positioned where the batten if pulled backwardly can bear against the uprigh t ribs of said lateral wall. In each of at least some of the courses, a batten is received by the provisions of the lateral walls of at least some of the concrete modules and a geogrid is anchored to the same modules, by the batten.</SDOAB >
