McGee

Piling

As a key support element to our core services, McGee Group has significant capability in a range of piling and wall installation techniques. These include large and small diameter bored piling, continuous flight auger piling (CFA) and restricted access piling. In most instances we self execute these works using our own employed labour and our own plant and machinery. Our in-house design service means that we are equally capable of undertaking contracts as a specialist subcontractor.

These techniques are used to form a variety of structures from; foundations (bearing piles), deep Basements, station boxes, underground car parks, bored pile retaining walls to cut-off walls and shafts. Our clients reap the programme and cost benefits of using a single contractor for all elements of the work, both below and above ground.

Techniques:

McGee Group has a range of rotary and CFA piling equipment utilised to carry out the majority of the geotechnical works on our projects, in all types of ground conditions.

Retaining Structures – Temporary and Permanent

Bored, cast-in-situ piles of either small or large diameter are frequently used as an efficient and economic method of constructing temporary or permanent retaining walls. These techniques are suitable for the provision of deep basements, underground structures and motorway cuttings, where working space is limited or adjacent existing structures require restraining. This enables the avoidance of excessive bulk excavation and helps to control ground movements.

McGee Group has the capability to install both continuous flight auger (CFA) and rotary piling methods. Pile diameters can be constructed up to 900mm for CFA and 1200mm for rotary methods.

We can construct these piles in most ground conditions, carrying their loads by friction, end-bearing or a combination of both, depending on the strata encountered.
