Drilling · Engineer Operated · 4WD Mobilised

Geotechnical & Environmental Drilling Sydney.

Headquartered in Marrickville, mobilised across the Sydney metro and into regional NSW: one 4WD-mounted rig, operated by the engineers who log what it brings up. Drilling for builders, consultancies and some of the bigger firms in Sydney.

01 · Borehole Drilling

Borehole Drilling.

An agile 4WD ute-mounted rig that gets on site fast and drills the ground Sydney is actually made of: Cumberland Plain clays and shales in the west, sands and estuarine profiles near the water, residual soils over sandstone everywhere else. Every borehole is logged by an engineer on site, not decoded from a driller’s notes afterwards.

  • Solid flight and hollow stem auger drilling
  • Dynamic Cone Penetrometer (DCP) at every hole; SPT on consultancy and commercial programs
  • Engineer-logged profiles, scoped to Sydney ground conditions
  • Rapid mobilisation across the Sydney metro and regional NSW

02 · Rock Coring

Rock Coring.

When the design needs more than refusal depth: intact cores from Hawkesbury sandstone and Ashfield shale, recovered, photographed and defect-logged so structural decisions rest on what the rock actually is.

  • NMLC rock coring with recovery and defect logging
  • Hawkesbury sandstone, Ashfield shale and interbedded profiles
  • Intact core for point load and strength testing
  • Advance booking and prepayment required

03 · Tight Access

Tight Access.

Terrace backyards, basement levels, side paths a wheelbarrow barely fits down. Access shouldn’t decide the quality of your engineering data. Motorised hand augers, tight-access coring and a 4WD-mounted rig reach the ground other crews quote around, with the finished surfaces protected on the way through.

  • Manual and motorised hand augering
  • 4WD-mounted rig where truck rigs stop at the kerb
  • Basement and restricted-height drilling
  • Low-impact setup and site protection

04 · Subcontract Drilling

Subcontract Drilling.

The rig and crew are available under your scope: engineering consultancies from boutique practices to some of the bigger firms in Sydney, environmental consultants running PSI and DSI programs, and builders and civil contractors who need holes without the overhead of an in-house crew. Your supervision or ours; engineer operated, always.

  • Engineer-operated rig on your program and your paperwork
  • Sampling, logs and chain of custody delivered in your format
  • Environmental sampling for consultant programs, with monitoring wells arranged through a bore driller under our scope
  • Standing arrangements for repeat capacity

Sunrise · Western NSW

Regional NSW

Whoop Whoop? We’ve Been.

Sunrise on a farm track, frost still on the paddock, mast already up. That’s what a regional program looks like when the rig travels self-sufficient. The 4WD rig runs the same engineer-operated standard hours from the nearest bitumen as it does in the Inner West, so consultancies and builders with work beyond the metro don’t have to lower the bar to get holes in the ground.

Who We Drill For

Your Scope Or Ours.

Builders

Boreholes for the site classification or investigation, booked around your program, and answers when the excavation finds something the report didn’t.

Engineering Consultancies

Subcontract rig capacity with engineer-grade logging: field data you can put your letterhead on without re-checking it.

Environmental Consultants

Drilling and sampling for PSI and DSI programs: clean execution, chain of custody kept, monitoring wells through a bore driller under our scope.

Bigger Firms & Majors

Reliable capacity for programs that can’t wait on a booked-out fleet: night works, staged access and standing arrangements included.

Common Questions

SFGEO drills boreholes, cores rock and runs tight-access and subcontract programmes for builders, engineering consultancies, environmental consultants and some of the bigger firms in Sydney. One 4WD-mounted rig, based in Marrickville and operated by the engineers who log what it brings up, mobilises across the Sydney metro and into regional NSW. Programmes are quoted per site, as a fixed fee in writing within one business day.
