Get quality data quickly with our CPT drilling rig and testing services.
CPT Experience You Can Count On
We have been in the CPT and drilling business since 2005. With over 17 years of experience in the game, we know how to get quality data – and what it actually means.
Three Birds With One Stone
Forget about mobilising three rigs on site for CPTs, drill holes and test pits. Get them all done at the same time from one rig, quickly. Mobilisation costs can be a huge component of your project budget so why waste it on moving lots of heavy equipment to site? Get core to calibrate your CPT with direct push borehole technology, or simply dig some test pits with the excavator on the same day.
CPT, Drilling & Penetrometer Testing with a Difference
Don’t be limited to flat dry sites. Get right into that landslide, down the bank or up the face, over the fence or through the trees on the day. Or go further by cutting a track in, right there and then. No need to prearrange for, and project manage an excavator to cut in access tracks for the conventional CPT and drilling rigs. We’ll even log the core for you if you wish.
Exceptional Data
Our plots are perfect for geotechnical interpretation. Clear information and a log of interpreted data calibrated to New Zealand standards give you everything needed to quickly understand the site.
Earthworks Testing
We have the gear for confirming fill quality and compliance, including two calibrated Nuclear Density Meters. We’ll come to site and take care of the compliance.
