Cannon Piling Increases Efficiency with Aarsleff’s Endura-Line Auger

Cannon Piling adopted an Endura-Line auger, supplied and manufactured by Aarsleff Plant & Fabrication, for a more efficient way of working.

In the heart of central London, Cannon Piling was contracted to install a secant wall comprising both 400mm and 600mm diameter piles, drilled to depths of up to 26.0 metres below ground level (BGL). The ground conditions presented a typical
sequence of made ground, sandy gravel, firm slightly sandy clay, a challenging environment for any piling operation.

Traditionally, Cannon Piling used standard flight augers requiring frequent hard facing to maintain cutting performance in abrasive ground. This meant a mobile welder was routinely present on site, typically for one full day each week, to apply wear protection. Not only did this come at a direct cost, but it also introduced indirect losses in productivity due to auger downtime and disruption to planned sequences of work.

To address this issue, Cannon Piling adopted an Endura-Line auger, supplied and manufactured by Aarsleff Plant & Fabrication. These augers are fitted with high-performance wear strips that are especially engineered to resist abrasion, reduce wear and eliminate the need for on-site hard facing.

The benefits of switching to the Endura-Line auger were immediately evident:

Zero Rework Required: Over the course of the 8-week programme, the augers did not require any maintenance or hard facing, a significant change from the prior  weekly routine.

Maximised Drilling Time: With no interruptions for rework, the site team maintained continuous productivity, achieving over 4,000 linear metres of piling within the 8‑week period.

Reduced Downtime and Hidden Costs: Without the need for mobile welding support, Cannon not only saved on direct costs, but also avoided the cascading inefficiencies of idle plant, re-sequencing work, and labour stand-downs.

Case Study

"The Endura‑Line auger has transformed how we manage tool wear. Not a single day was lost to reworking augers, meaning the team could stay on production continuously. It’s a smarter, more efficient way of working."
