Open Auger Bored Piles
Open bore piling is a universal method of piling and it can be used on both small and big-scale projects. The rotating auger is drilled into the ground and then withdrawn, reaming out the soil. The process is repeated until the desired depth has been met. After the steel reinforcement is placed, the bored hole is filled with concrete to complete the pile. By varying the length and diameter of the piles different bearing capacities can be achieved.
At Limaks, we have access to a wide range of drilling rigs, which ensures that we can choose the right method to complete your job most effectively. Upon a site inspection our engineers will decide on the best bored piling rig and the length and diameter of the piles.
Where to use
Wide range of sizes
Ideal for cohesive soils
Open bore piling is an ideal piling method for use in cohesive soils such as clay and silt, where there is no groundwater and a stable bored hole can be formed. The piles take their load-carrying capacity from the friction generated between the soil and the surface of the pile shaft; therefore, this type of piling is often used to support structures where the highest load-bearing capacity is required.
Open bore piling causes minimum vibration, which makes it ideal for use next to buildings and underground services.
Some of most common applications are:
- Multi-storey office buildings
- Underground structures
- Retaining walls where high levels of reinforcement are required
- Constructions near built-up residential and commercial areas
Can you arrange for pile calculations and design to be submitted to the local authority?
Yes. We can produce structural drawings for the piling work and submit them to the local authority building control before we start the works.
What maximum depth and diameter can you achieve?
Our bored piling machines are able to install piles of up to 600mm in diameter and up to 40 metres in depth.
Can you drill through rock?
Yes, we have special rigs for drilling hard strata such us moorum, soft and hard rock.
