Piling Methods and Capacity
Bored, CFA, driven, screw and sheet piles, rock anchors and micropiles, installed with our own rigs.
Our piling capability has grown from our bridge and marine work, with in-house engineering for temporary works, pile gates and rig platforms. We are able to provide:
- Bored piles up to 1500 mm diameter using our Soilmec SR-75, SR-65, SR-45 and Enteco rotary drilling rigs
- Bored piles in hard rock using down-the-hole (DTH) hammers up to 900 mm diameter
- Continuous flight auger (CFA) piles in 600 and 750 mm diameter, up to 26 m long, and secant pile walls
- Soil displacement piles at 600 mm diameter to 24 m long
- Driven steel, timber and concrete piles up to 15 MN using hammers from 15 kJ through to our 210 kJ Junttan HHx210
- Steel screw piles to 900 kN capacity
- Sheet piles installed by vibration, by excavator or crane-suspended hammer
- Rock anchors and micropiles from 76 to 305 mm diameter, drilled using an excavator-mounted drifter or DTH
- Marine and over-water piling from our jack-up barge, spud barges and barge-mounted piling gates
Along with our specialist piling equipment, we have a range of excavators (8 t to 45 t) and crawler cranes (50 t to 275 t) ready for your next project. Recent piling projects include the Davis Street Sewage Pump Station in Smithton (the first CFA secant piling application of its kind in Tasmania) and the Macquarie Point Sewage Pump Station in Hobart.
Testing and verification
GRLWEAP, PIT, PDA, CAPWAP, cross-hole sonic logging and Osterberg cell testing through our third-party testing partners, plus static load testing with our own hydraulic cylinders. Rig logging records torque, depth and pressure on every rotary pile, RTK GPS sets out each pile to within 10 mm, and reality capture to plus or minus 5 mm produces the as-built pile record.
From enquiry to handover
Budget and firm quotations from drawings and geotechnical reports; temporary works, pile gate and rig platform engineering; reinforcing cage fabrication in Latrobe; multi-rig mobilisation for large programmes; and QA, ITP and as-built records captured digitally in BridgePro OS for full transparency to the Principal.
