Bored Piling Solutions Ivor King offer a range of Bored and CFA piling services that integrate with our sheet piling solutions

Bored piling uses reinforced concrete piles formed in the ground to support structures carrying significant vertical loads. It can be used across a wide range of ground conditions and is often selected where unstable or difficult soil strata need to be overcome. The most appropriate bored piling method depends on the design loads, ground investigation, access and surrounding site constraints.

CFA piling uses a continuous flight auger to drill and form the pile, offering a virtually vibration-free solution with strong load-bearing capacity. Rotary piling is suited to a broad range of ground conditions and pile diameters, while bored displacement piling displaces the ground rather than removing it, which can reduce spoil and improve production efficiency. We assess the project requirements before recommending the most suitable technique.

A contiguous piled wall is formed from closely spaced bored piles with a small gap between neighbouring piles. A secant piled wall uses overlapping piles to create a more continuous barrier and may be selected where greater water resistance is required. Both can provide earth retention for basements and other excavations, subject to the project design and ground conditions.

Yes, where the site investigation and design confirm that the method is suitable. We operate specialist rigs capable of installing secant or contiguous piled walls within approximately 100 mm of an adjacent structure. This can be particularly valuable on basement and restricted urban sites where maximising the usable footprint is important.

Yes. As a multi-disciplined piling contractor, we can design and deliver integrated bored and sheet piling solutions where a project requires elements of both. Some of our rigs can install both sheet piles and CFA piles, which may reduce plant movements, transport requirements and time on site.

Useful information includes the structural loads, site layout, ground investigation and groundwater data, access and headroom, nearby buildings and services, environmental limits and the construction programme. We can support the project from initial feasibility and design through to installation, testing and completion.
