King Posts are isolated steel columns that are installed along the line of the proposed retaining wall typically at centres between 1 and 3m. The space between the posts is filled, over the retained height, using a variety of different solutions but most commonly a precast concrete panel. The method of King Post Walls involves drilling a hole with a high-powered CFA, large diameter or mini piling rig and then filling it with concrete and installation of an H beam. This allows concrete pre-stressed panels to be inserted between the webs of the H sections, which after excavation results in the finished embedded retaining wall. King Post Walls may be used for different retention applications and heights in different ground conditions, including rock.
