1 Quote, 1 Invoice

Let Backyard Bores and Geotech Drilling reduce your paperwork and administrative overhead by providing you with one quote to cover NDD, underground utility locating, concrete cutting and coring, drilling, providing samples and installing monitoring wells.

We have a long-term working relationship with Mackay's best:

  • NDD (vacuum truck) company
  • Underground utility locators with GPR (ground penetrating radar)
  • Concrete cutter and corer (up to 300mm thick)

Experience, skills & local knowledge

Backyard Bores & Geotech Drilling Pty Ltd have drilled thousands of soil sampling and groundwater test holes and installed hundreds of groundwater monitoring wells between Bowen and Rockhampton over the last 20 years.

We have drilled and installed 4 times* the number of monitoring wells around Mackay compared to any other drilling company. Why? Because our team uses the right equipment with the right processes and the methods for the right reason by utilising wisdom, judgment and discretion in the pursuit of your project's goals.

Licensed drillers - Every monitoring well logged

Backyard Bores & Geotech Drilling Pty Ltd have Queensland licensed drillers, and we log every monitoring well we drill as required by the obligation of our licenses. Ask the other drilling companies quoting on jobs if they are using a licensed driller and if that driller logs EVERY monitoring well. Consequences for all involved in not logging monitoring wells are harsh.

Every monitoring well deeper than 6m MUST be drilled by a licensed driller, and a log submitted.

Workplace Health & Risk

We care about our team's health and risk levels at work and have WH&R Policies and Procedures, WH&R Plans, SWMS, and JRAs that put the crew first. As of January 2024, we have a zero lost time injury rate since 2012.

PFAS PFOS Firefighting Foam

We have drilled hundreds of soil sampling and groundwater test holes and installed dozens of groundwater monitoring wells in suspected/confirmed PFAS / PFOA areas. Our rigorous PFAS drilling quality control process allows for the most accurate samples possible.
