Bored piles are a very effective, state-of-the-art construction element with many applications in foundation and civil engineering.
Process
A temporary casing is installed and soil drilled out using specialised tools. If the hole requires support to remain open, additional casing or, occasionally, drilling fluid can be used. Full length reinforcing steel is lowered into the hole which is then filled with concrete. Bored piles can be drilled to depths in excess of 60m and typical diameters range up to 2.4m.

Common uses
- As heavy foundations, securing deep excavation especially close to existing buildings as well as stabilising and retaining slopes
- In a variety of infrastructure projects such as tunnelling, road or bridge construction as well as flood protection
- Transfer to deep rock or competent soils and withstand high loads
- Retain ground alongside an excavation pit or close to adjacent buildings, often combined with other techniques such as ground anchors or soil nails
- For slope stabilisation to prevent landslides, or protect existing buildings
Advantages
- Can support high loads
- Various diameters available from 450mm upwards
- Minimal settlement and deformation
- Minimum vibration
Quality assurance
We use a variety of quality assurance methods for our products including top down and integrity testing, bottom bi-directional pile load tests, and digital recording and logging of the execution parameters.
