Auger Bored Piles

150-600mm diameter to 24m depth

This piling method is ideal for use in cohesive soils. The rotating auger screws into the strata reaming out the soil. Once the required depth has been achieved the steel cage and concrete is placed.

These highly mobile rigs are economic to use on large open sites with cohesive ground, and on some chalk or sand, which have good access. Smaller models are suitable for internal use. (The example shows the pile being formed using temporary casing to prevent sides collapsing or water entering the open bore).

As a rotary auger causes minimal vibration it is ideal for use next to buildings or underground services. Tremmie techniques can be used if water is present.

A number of our rigs can install this type of pile and the choice is dependent on pile load, size of site and the number of piles to be installed. We have smaller rigs such as G.P. Services, Kitten and Klemm for use on resticted sites. If piles need to be formed through loose or wet strata a temporary cased, continuous flight auger or driven piled solution may be preferable.

The vast range of our piling rigs means that we can offer a short lead-in time and an economical solution for most projects.
