King Post walls are a simple, quick and economical piling installation method.


King post wall

They are constructed by drilling a hole with a high powered CFA piling rig and then filling it with concrete and installing an H beam.
This allows concrete pre-stressed panels or sleepers to be inserted between the webs of the H sections, which after excavation results in the finished embedded retaining wall.
They are proving ever-more popular with our customers and here’s 15 reasons why you should consider using them:

1. King post walls are a cost-effective earth retention system and a cheaper alternative to sheet pile retaining walls.
2. King post walls are suitable for most earth retaining requirements including embankment retention and flood defence walls.
3. King post walls are suitable for temporary or permanent retaining walls.
4. King post walls can be constructed from a low-level piling platform avoiding the costs associated with building up platform levels when constructing contiguous piled walls.
5. King post walls are suitable in different ground conditions, including rock.
6. King post walls are quick and simple to install compared to other piled retaining systems.
7. King post walls are silent and vibration-free compared to sheet piling retaining walls.
8. King post walls can be designed and constructed with various rig sizes to allow for tight access sites but still achieve the retaining requirements when using larger rigs.
9. King post retaining walls can be designed for 120-year design life for highway and Network Rail requirements.
10. King post walls can be constructed using various types of infill panels and architectural requirements.
11. King post walls can be constructed on tight boundary conditions and up against existing structures with minimum deflection and damage.
12. King post walls can be tied back using anchors.
13. King post walls are ready for immediate follow on works.
14. King post walls are suitable to construct with acoustic fences as part of the construction detail.
15. King post walls can be used as bearing piles for superstructure support for steel frame buildings and avoiding constructing in-situ pile caps.
