King post walls are a cost-effective system of temporary or permanent retention using beams and precast concrete panels.
King post walls are a simple and quick installation method. They comprise boring a hole with a continuous flight auger (CFA) piling rig, filling it with concrete, then installing an H beam. This allows concrete pre-stressed panels or sleepers to be inserted between the webs of the H sections.
Excavation then results in the finished embedded retaining wall.
