Bored piles are a very effective, state-of-the-art construction element with many applications in the foundation and civil engineering.

Common uses

As heavy foundations, securing deep excavation especially close to existing buildings as well as stabilizing and retaining slopes
In a variety of infrastructure projects such as tunneling, road or bridge construction as well as flood protection
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 stabilization to prevent landslides or protect existing buildings
Process

A temporary casing is installed and soil drilled out using specialized tools. If the hole requires support to remain open, additional casing or 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.

Advantages

• Very high load capacity
• Various diameters available from 450mm upwards
• Can be installed in a wide range of soil and rock conditions
• 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.
