What is a driven pile?

A driven pile is a prefabricated steel, timber or concrete column that is ?driven? into the ground using a pile driver machine. The pile is installed by impact hammering, vibrating or pushing it into the ground to a predetermined depth.

Performance Foundations recommend bottom driven piling when ground conditions are poor or in situations when piles are required to carry high loads and deep foundations are not possible.

Driven piles are sometimes referenced as displacement piles. During the installation process, soil is moved as the pile is driven into position. They are particularly suitable for accommodating substantial horizontal loads and vertical tension loads created by large bending movements, horizontal reactions and uplift and heave reactions, as well as large axial loads. It is particularly good for brownfield sites because costly spoil removal is not needed.

What are the methods of pile driving?

Choosing the correct process to install driven pile foundations is determined after close consideration of the site, ground conditions and type of project.

How do I know if I need piling for my project?

Piling is required for many different construction projects. We will work with you to help you determine what kind of foundation works your project requires and advise on the best options available to you. Our team also work alongside construction architects, site managers and engineers to keep you fully informed on what is needed to progress your project to the next stage.

Drop Hammer Pile Driving

A pile driver hammer is started by raising a weight the same size as the pile and releasing this on the pile head to drive it into its ground position.

There are two types of drop hammer machinery available;

  • Double-acting pile hammers
  • Single-acting steam or air hammers

Vibration Pile Driving

The vibrating pile hammers utilise a system of counter-rotating weights that is fastened to the pile. The vibration motion can both drive and extract a pile. Vibration pile driving is commonly used to extract steel ‘H’ piles.

Site Requirements for Driven Piling Methods

The site needs to be dry, firm, flat and level, and capable of sustaining the load of the piling rigs which typically will weigh up to 10 tonnes. Access roads need to be suitable for normal delivery vehicles.

  • Quick and efficient form of piling
  • Economical, mobile and yet still powerfu
  • Low noise and low vibration impact on the environment
  • Bottom driven piling can be installed successfully into most grounds, including peats, soft clay and loose sands
  • Bottom driven piles are self-testing when driven to set
    Permanent casing prevents any risk of concrete/grout loss thus ensuring pile integrity
  • Concreting in the dry in a single operation to a controllable level
  • Good axial and shear capacity
  • They have a high-column buckling strength and energy-absorbing capability so that they can be driven hard and are difficult to damage
  • They are preformed and no preparation is needed at the site before driving
  • They have a high load capacit
  • Bottom driven or tubular steel piles come in a large range of sizes and thicknesses available
  • The wall thickness can be varied throughout the pile length
  • No spoil needs to be removed
  • Minimal site preparation is needed
