Mini piling

We specialise in mini piling solutions that provide the strength and precision needed to keep complex projects moving – safely and efficiently. 

Our fleet of specialist mini piling rigs delivers technical solutions in the most constrained environments, even where site access is limited. Whether we are working in remote and mountainous environments, accessing existing structures, operating in close proximity to live infrastructure or in low headroom conditions, we offer a full range of techniques to meet the site conditions. 

Our rigs are compact, versatile and highly mobile – capable of being craned into position or maneuvered through tight internal spaces. We’ve also developed short-mast configurations for our larger rigs, enabling the installation of piles up to 900mm in diameter when working next to live railway lines during operating hours. 

We also offer a wide selection of high-capacity, small-diameter piles that can be installed in almost any ground condition with minimal site preparation. Our full range of mini piling techniques includes: 

• Augered mini piles: these can be installed with little or no vibration enabling piles to be placed as close as 1 metre from an adjacent building or structure. This technique is regularly adopted in stable cohesive soils at a shallow depth and is particularly effective where there is a requirement for deep reinforcing cages to be installed. High-capacity piles of up to 660mm diameter can be constructed to maximise load bearing capacity. 
• Sectional flight auger (SFA): SFA piles, of up to 600mm in diameter, are installed using hollow stem augers and are drilled in short sections to the required pile depth. They are typically used in mixed and non-cohesive ground and where the depth of the reinforcing cage can be limited. The piles are then concreted through the hollow stem and to the bottom of the auger string as they are removed from the ground.  
• Drilled mini piles: suitable in most ground conditions drilled piles are particularly effective in problem ground – for penetrating rocks, boulders, general obstructions and mass concrete. They can provide high capacity when advanced into bedrock. 
• Self-drilled micro piles: these are suitable for a variety of ground conditions including sand, gravels, clay, made ground and weathered rock. They can be installed through existing mass footings and base slabs and can provide high tension and compression loads.
