Which types of pile are available to you?

dreamstime_xxl_6040678There are many different types of pile for different types of conditions.

Here is a basic guide to the types of pile we can work with.

Displacement Piles

Mini Piles 100, 150 & 175mm diameter available

Mini piles are steel tubular castings driven into the ground with an air powered bottom driven mole until a “pile set” is achieved. The casing is then cut off to the exact height required and filled with C35 concrete and a central T16 bar left projecting to tie into the pile cap.

Cased Piles 225 & 273mm diameter available

These are similar to mini piles but normally driven to a set depth with a drop hammer rig mounted on a crawler rig.

Bored Piles Auger piles – 150 – 300mm diameter available

Holes are drilled into the ground to suitable strata by a compact hydraulic crawler rig. The bored holes are then filled with C35 concrete and T16 bars.
