King post/soldier piles and lagging walls are a cost effective system of temporary or permanent retaining wall using beams and pre-cast concrete panels.
Most retention applications and heights in different ground conditions including rock
Often used for basements, embankment retention and flood defence walls
King post walls are a simple and quick installation method. They comprise drilling a hole with a high powered, 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.
Quick to install
Cost effective compared to sheet and concrete piled walls
