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.
