Legion’s experience injecting slurries into overburden, transition zones, and fractured bedrock settings makes this partnership a natural and complementary fit. The trend towards in-situ management of PFAS versus groundwater extraction

Most environmental consultants would never allow soil samples to be taken with auger methods in soils that could would be conducive to direct push methods. It is important to carefully follow sampling protocols and to use proper decontamination techniques between sample locations.

Legion Drilling was created for this buyout by Numac’ s long time General Manager. As part of the purchase agreement Legion acquired the rights to continue using the Numac name. This helped ensure a smooth..

Recently captured a couple of great shots with crews undertaking drilling works on the Sydney “Metro” project in New South Wales (NSW). The image above shows one of our Boart Longyear DB520 Multipurpose rigs completing an 50m HQ3 geotechnical core location in the shadow of the HMS Endeavour replica.

The next presentations will be dedicated to MiHPT (Membrane-Interface & Hydraulic Profiling Tool) and UVOST (Ultra-Violet Optical Screening Tool), two direct sensing tools that have revolutionised the way we investigate contaminated sites thanks to their high resolution and real-time visualisation capabilities.

At Numac we thrive on providing solutions for challenging drilling programs. Our loyal clientele return for the support of a drilling contractor that can deliver in high risk and high performance situations.

BOS 200® has been implemented in hundreds of sites to effectively treat LNAPL source zones, fuel oxygenates, alcohols, glycols, and cyclic ethers. BOS 200® is a complete system effecting accelerated biodegradation processes on an activated carbon platform that includes

Sydney based R20 Sonic crews have been on a 13 week tour which included quarantine, 4 states, 4 projects and a total of 6400km mobilization. Project requirements included 150mm production bores, Environmental monitoring wells, and Vibrating Wire Piezometers for a Geotechnical client. The rig completed projects in Queensland, South Australia, Northern Territory and New south wales.

Despite its small stature the Geo 205 is still capable of HQ coring to 30m quite comfortably and it automatic SPT hammer ensures safe operation. The tight squeeze is assisted but fully remote control operation allowing the driller to keep well out of harm’s way.

The bore shall be constructed by a suitably qualified driller who possess the appropriate experience and the relevant class of licence that the state or territory deem necessary. An appropriately licenced driller shall be on site at all times during bore construction and decommissioning activities.”

Never a dull day as a drilling contractor. Our drill crews in Adelaide were part of the government PR machine this week undertaking a deep groundwater monitoring program

Geoprobe 6620 (R1) returns to service in 2020 after a full refit and upgrade by the Numac maintenance and engineering team. View a short video of the results.

At this point, 20+ years into the development of direct sensing technology there have been a multitude of arguments presented touting the technical and financial advantages of High-Resolution Site Characterisation (HRSC) using Membrane Interface Probe (MIP), Ultra-Violet Optical Screening Tool (UVOST) and Hydraulic Profiling Tool (HPT). 

To better service north QLD clients we now have a Geoprobe 7822Dt operating from a satellite base in Cairns Australia.

This short video is a small window into what kinds of drilling projects are going on at Numac on any given day. As a tier 1 drilling contractor we can provide high quality drilling services including Sonic, remote access diamond coring, geotechnical, overwater and contaminated land investigations with Geoprobe machines.

This is what a Geoprobe 6620 looks like stripped down to its component parts. Our fitters have recently commenced a complete overhaul and upgrade of “R1” our Geoprobe track mounted drilling rig.

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.

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.
