Types Of Pile
Which types of pile are available to you?
There 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
20 & 100mm 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 – 350mm 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 H16 bars.
