Restricted Access Piling in Leeds

Dawson FE completed restricted access piling inside a live Leeds paper mill, installing four 273mm bottom-driven steel-cased piles for a new machine base.

Cased Auger Piling in Scotland

Dawson FE completed 450mm diameter cased auger piles in Scotland, using 508mm temporary casing through soft alluvial deposits before founding into dense gravels.

SFA Bored Piles at JCB Golf & Country Club

Dawson Foundation Engineering installed 88 No. 300mm diameter SFA bored piles at JCB Golf & Country Club in Uttoxeter, with the piles designed in-house to support compressive, tensile and shear actions.

SFA Piling In Surrey

Flooded land whilst doing SFA piling in Surrey

Project Overview Piling is not always picture-perfect. It is often carried out in difficult ground, adverse weather and under challenging site conditions. Our newly acquired Klemm 709 piling rig did not even have time for a clean-down before being put straight to work on a site in Surrey. The project required the installation of 31 no. 300mm diameter hollow stem SFA bored piles, delivered during one of the wettest months on record. Ground Conditions & Site Constraints The working area had already been excavated, with concrete blinding installed across the working platform. Persistent rainfall quickly turned the site into extremely challenging ground conditions, testing both access and stability throughout the programme. Despite the difficult environment, the Klemm 709 performed reliably from day one, completing the works safely and efficiently. Installation Method The scheme utilised Sectional Flight Auger (SFA) piling, a versatile bored piling technique suited to restricted and variable ground conditions. The hollow stem system allows controlled drilling and concrete placement, providing a robust and efficient foundation solution. Engineering & Delivery As with all DFE projects, the piling works were supported by in-house engineering expertise, ensuring the pile design met the required structural loading criteria and ground parameters. This project demonstrates DFE’s ability to deliver specialist commercial piling solutions in demanding conditions, maintaining programme and quality standards even when the weather does its worst. What’s Next Following completion of the Surrey works, the Klemm 709 moved on to its next project in Sevenoaks — hopefully with slightly drier ground conditions. To discuss an upcoming project requiring SFA or bored piling works, get in touch with the DFE team.

CFA Piling Works in Preston

Preston CFA piling works

Project Overview As the sun set on 2025, the Dawson Foundation Engineering (DFE) team concluded the year on site in Preston, delivering specialist Continuous Flight Auger (CFA) piling works for a construction project requiring high-capacity foundations. The scope of works involved the installation of 300mm diameter CFA piles to depths of up to 13.0 metres. The piles were installed through a sequence of layered cohesive and granular soils, requiring careful control during drilling and concreting to ensure consistent pile formation. Pile Design & Installation All CFA piles were designed in-house by DFE’s Chartered Engineer to accommodate significant compressive, tensile and shear loads. This integrated design-and-install approach allowed the foundation solution to be tailored precisely to the ground conditions and structural requirements of the scheme. The use of CFA piling provided a fast and efficient foundation solution while maintaining excellent control of spoil and concrete placement throughout the installation process. End of Year Operations With site operations concluding for the year following completion of the Preston works, the DFE team successfully closed out a busy and productive 2025. While site activities paused for the festive period, the DFE office remained open, continuing to respond to client enquiries up until Christmas Eve. Our Expertise Dawson Foundation Engineering designs and installs a full range of specialist piling and foundation solutions, including: Sectional Flight Auger (SFA) piles Continuous Flight Auger (CFA) piles Bottom-driven steel cased piles ODEX piles Screw piles In addition to piling works, DFE also designs and constructs ground beams, slabs and pile caps, providing a fully integrated foundation service from concept through to construction.
