"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."
For Any Ground Condition.
Sectional Flight Auger is our go-to mini piling method for extensions, new builds, and domestic work. Open bore for stable clay, grout injection for tricky ground. Compact rigs keep costs down, and the sectional design also handles low headroom when you need it.

Versatile Installation. Restricted Access Ready.
Our Go-To Method for Everyday Projects
SFA is the auger-based mini piling method we use most often. Gardens, extensions, new builds - it's versatile enough for almost any domestic or commercial project. Compact rigs mean lower transport costs and less site damage, same as standard mini piling.
The real advantage is flexibility. In stable clay, we use open bore drilling. When ground is wet or unstable, we switch to grout injection - pumping concrete through the auger as we drill. And if headroom is tight, the sectional design works in spaces as low as 2.4 metres.

Open Bore or Grout Injection
We match the method to your ground conditions.

"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."
"What a breath of fresh air to deal with a company that exceeds all of your expectations. 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. Thank you for a job 'very well done'."
"We chose them for our extension. The sales person Ben was extremely helpful with his comments and always available to discuss matters and never missed a call back. 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."
