AUGER (SFA) PILES
Mini Sectional flight auger (SFA) piling is an auger bored replacement pile solution for restricted access piling which provides the ability to install piles in low headroom or restricted-access sites. SFA piling offers a similar solution to CFA piling, except the auger is made up of shorter sections of hollow stem continuous flight auger.
WHAT THEY’RE USED FOR
Sectional flight auger (SFA) piling is suitable in all unobstructed conditions including made ground, clay, weak rock, gravel, glacial till, and ground with high water tables where there is restricted access or limited headroom.
SFA mini piles are formed using a sectional hollow stemmed auger. This replacement technique produces the arisings from the bores in most ground conditions. Once the bore is produced to design depth, concrete or grout is then pumped through the auger hollow stem as it is withdrawn. Concrete simultaneously fills the void left by the auger extraction before reinforcement is inserted.
Installation is monitored and controlled using onboard instrumentation to ensure quality standards are maintained.
WHY USE SFA Piles?
- Fast, quiet and virtually vibration-free
- RB in-house purpose-built rigs
- Quiet installation compared to other methods of piling
- Suitable for most ground conditions
