This highly capable truck mounted geotechnical rig was commissioned in late January 2018. It's immediately proving a big hit with our clients combining great mobility and speed of operation.
The new probe detects volatile contaminants with the MIP, measures soil electrical conductivity with a standard (MIP) dipole array, and measures HPT injection pressure using the same down-hole transducer as the Geoprobe® stand-alone HPT system.
Numac recently completed a mineral exploration drilling program with a sonic rig in unconsolidated formations for Nickel Laterite.
Our new Volvo FH13 540 Prime Mover looking smart in the her new skin. With the large distances we move rigs each year it is certainly nice to know that have reliable, safe and comfortable equipment making these long road-trips comfortable fro the drill crews.
One of the highlights of 2017 was being involved in the Sydney Metro Geotechnical investigation in Sydney Harbour. Numac was presented with an opportunity to use one of our Sonic drill rigs from a overwater in close proximity to the Harbour Bridge.

Numac are very proud to be awarded 3rd party accreditation from Best Practice Certification for our Safety (AS/NZS 4801), Quality (ISO 9001) and Environmental (ISO14001)
As Australia's leading provider of High Resolution Site Characterisation (HRSC), Numac welcomes back David Heicher from Dakota Technologies for his keynote presentation at Cleanup 2017:
".....look for a cost-effective method for characterising shallow groundwater resources in remote Northern Australia"
Numac Drilling Services Australia was awarded a public tender by Hunter Water to manage and undertake the drilling and installation of 15 municipal water production bores within the existing use regional aquifer.
Using tracers to Investigate aquifer recharge. A wide a range of tools wre employed to gather data including monitoring wells, the Hydraulic Profiling Tool (HPT), Geoprobe push tube soil sampling and the SP16 groundwater sampler in this investigation.
Early 2016 saw 2 Geoprobe machines running double shift for a large scale environmental assessment. The investigation included a large Membrane Interface Probe (MIP) investigation which we believe was a first for Singapore.
Sonic Drilling is taking off in Australia and is quickly becoming the preferred tool in both Environmental and Geotechnical site investigations. After a couple of years of use this is the lowdown on where we see the value.
The HPT provides a continuous hydrostratigraphic log of the subsurface that provides relative hydraulic conductivity of the formation. Soil lithology is also mapped along the vertical profile of the subsurface. Identify pathways and calculate permeability and static water levels in real time...
Run on a Geoprobe drilling rig, the UVOST systems makes for a much more productive day in the field. Real time delineation LNAPL plumes can be conducted with speed and with complete confidence. There is a greatly reduced requirement for soil sampling, laboratory analysisand groundwater wells.
AUSTRALIA'S Premier drilling contractor
Numac Drilling Services is Australia’s premier environmental, Geotechnical and Sonic drilling contractor. With permanent office locations in Brisbane, Melbourne and Sydney, Numac has access much of the country at competitive rates. With 20 years in the industry and a huge variety of equipment we have all of your needs well covered. Our safety, quality and environmental management systems are all third party accredited which ensures we can get on any site with minimal effort to our clients. Our experience rages for small scale environmental investigations through to full remote camp mining projects and international projects. Numac provides Australia’s most comprehensive suite of High Resolutions Site Characterisation (HRSC) systems for contaminated land investigation and some of the most power sonic drilling rigs in the market.
Numac has over 10 years experience in chemical injection for the purpose of in-situ chemical oxidation/reduction (ISCO/R). This system seen in this video is the result of 10 years of deveopment and continual improvement of the process.
