King Post is suitable for applications where space is at a premium and traditional gravity solutions such as crib walls may take up too much space. If boundary contraints are present that prevent the neccessary excavation required for installation, then King Post walls are a viable alternative.
King Post offers a simple and quick installation method: drill a hole with a high powered CFA piling rig and then fill it with concrete and installi an H beam. This allows timber sleepers or concrete pre-stressed panels to be inserted between the webs of the H sections which, after excavation, results in the finished embedded retaining wall.
The infill panels are available in a range of finishes, with an attractive timber-look concrete panel available where aesthetics are important.
