At Performance Piling, we recommend Bottom driven piling (also known as tubular steel piling) when there are poor ground conditions or when the piles need to carry high loads and deep foundations are not possible.

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.

We use recycled steel tubes for our bottom driven or tubular steel piles, which enables us to deliver cost-effective and environmental benefits to our customers.


Bottom driven piling is where close ended thin walled steel lining tubes are pile driven in lengths to a pre-determined set or depth, depending on design criteria using a cylindrical drop hammer operating within a casing striking a dry mix concrete plug. The steel tubes are typically 2 to 3 meters in length and are joined by full fillet welding as installation proceeds.

Site Requirements

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.

Bottom driven piling has a number of advantages:

  • Quick and efficient form of piling
  • Economical, mobile and yet still powerful
  • 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 capacity
  • 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
