Chris Designer

Limaks carried out works at my property in Acton. My initial enquiry was handled promptly and I was talked through the project and told what to expect. The team itself was very professional, considerate, and courteous throughout the entire project and ready to answer any of my questions. I felt I could trust them 100% in terms of competence, effort, and security.

Service Description

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 The rotating auger is drilled into the ground and then withdrawn, reaming out the soil.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.

Characteristics

Where to use

Wide range of sizes

Open bore piling method allows for a greater range of sizes and depths of piles, which allows for achieving different bearing capacities.

Ideal for cohesive soils

This method is ideal for use in cohesive soils, such as clay, where the bored hole remains stable, dry and open.

Minimum vibration

Open bore piling method causes little or no vibration; hence it is ideal for use against adjacent buildings or underground services.

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

Popular Questions

Limaks Brochure

  • 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.
