WHY SFA PILING

Versatile Installation. Restricted Access Ready.

Our Go-To Method for Everyday Projects

SFA is an auger-based piling method for extensions, new builds and sites with restricted access. Suitability depends on the ground conditions and engineer's design. Compact rigs help keep transport costs and site disruption down.

The installation method is selected to suit the ground and design. Open bore drilling or grout injection may be appropriate, depending on the conditions. Where no ground investigation report is available, an assessment may sometimes be possible on day one.

SFA PILING FAQ

Frequently Asked Questions

Common questions about sectional flight auger piling for low headroom and internal works.

SFA (Sectional Flight Auger) piling uses modular auger sections (1-2m lengths) instead of a single continuous auger. This allows the rig to work in spaces with low headroom - as little as 2.4 metres. Suitability and capacity depend on the ground conditions and engineer design.

"What can I say, the team were a pleasure to deal with from start to finish. My wife and I did a fair amount of due diligence... Our experience was that they seemed to go the extra mile. A shout out to Barrie the project manager but of course not forgetting Lenny and Baz who worked tirelessly throughout. And a special thank you to Ben Crabb - right from our first conversation, you proposed options and were so helpful and informative."

"A really nice family business that we couldn't recommend more highly. We had a 14m x 11m foundation concrete slab with mini piles completed within their estimation of 4 weeks... The building inspector said he wished all his clients were up to their standards! From my many phone calls with Ben from the outset through to Ricky, Barrie and Shane (3 brothers) they are all so friendly and helpful."

From my first contact with Barrie in the office to the two hardworking men, Dan and Lenny who carried out the job, I have been so impressed with their professionalism, capability and friendliness.

Ricky the project manager explained what was happening throughout the procedure with phone calls and I must mention Rachel for any issues we had. Overall very good job done."
