The Soilmec SF-50 is a dedicated CFA piling rig. We currently operate 4 of these machines making them the workhorse of our fleet.

The SF-50 is self-erecting, quick to mobilise and will drill up to 25m depth with a diameter range of 300-900mm. It is ideal for quick and efficient production, especially in soft soils.

Each of the rigs is fully instrumented to monitor drilling parameters and concrete pressures and ensure quality of pile construction.

We have recently invested in low headroom conversion kits to fit these machines, ideal for projects where height restrictions may be in force or where space is limited. This kit removes the folding mast extension significantly reducing reducing setup time and space. The rig has been frequently employed with a shortened mast on various smart motorway schemes, working in narrow lane closures with regular rig moves.
