The Piling Services We Offer

Mini Piling

We specialise in the provision of mini piled systems, offering a mini piling service utilising piling rigs from 1.5 to 15 tonnes.

CFA Piling

Continuous Flight Auger piling involves drilling downwards with a hollow auger. Causing minimal disturbance to the surrounding area.

Open Bore Piling

Open bore piling allows for a greater range of sizes and depths of pile. Suitable for most ground conditions.

Below Ground Retaining Walls

The method is generally used for sites where groundwater is not an issue. Retaining walls are created by installing a series of piles close together, positioned so that they almost touch each other, leaving a gap of around 100mm between each pile, forming a robust retaining wall.

These embedded piles create structurally sound walls for basement excavation. There are two main systems for creating retaining walls: contiguous bored pile walls and secant bored pile walls.

Secant Piling

This retaining bored pile wall system involves the installation of the piles in such a way that they overlap using a male and female pattern. The secant piling technique forms a watertight seal and thus provides a solid barrier against groundwater flow.

Cased Piles

These piling services work by using temporary casings to create a watertight seal through wet or unstable ground conditions down to a more stable strata of clay below, which enables us to drill beyond to the specified depth. The benefits of case piles are less over break, reduced concrete consumption, open clean pile bore for easy inspection and the ability to achieve greater depths.
