Piling services - bored piles
Bored piles are a very effective, state-of-the-art construction element with many applications in foundation and civil engineering. They are typically used as heavy foundations, and suitable for infrastructure projects such as tunnelling, road or bridge construction, and flood protection, as well as ground retaining and slope stabilisation applications
Bored piles are a very effective, state-of-the-art construction element with many applications in foundation and civil engineering.
Typical applications
As heavy foundations, securing deep excavation especially close to existing buildings as well as stabilising and retaining slopes
Infrastructure projects such as tunnelling, road or bridge construction, and flood protection
Transfer to deep rock or competent soils and withstand high loads
Ground retaining alongside an excavation pit or close to adjacent buildings (often combined with other techniques such as ground anchors or soil nails).
Slope stabilisation to prevent landslides or protect existing buildings
Installation 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.
