Roads. Tunnels. Dams. Mines. Ports. Residential. Commercial. Groundwater.

It's too important to guess. 

Have you met the Brights?


We are taking a light-hearted look at a serious issue: mitigating risk from a significant seismic event. Most New Zealanders understand this is a 'when' not 'if' scenario. But what can really be done to protect assets, and people?

RDCL goes Wireless with Seismic


Gone are the cables and difficult traffic management when RDCL can deploy a wireless seismic array pretty much anywhere

Used in conjunction with RDCL's current seismic systems we can look deeper and and produce more data for Sub-soil Site Class Assessment.


The Geometrics ATOMs are a welcome addition to our asset pool.

Say Hello to the Tiger


Upgrading the vehicle fleet is fun when you end up with 4x4 Vans that can crawl up mountains and safely transport all RDCL's people and tooling around the country.  

Purposely commissioned from VW with increased ground clearances, diff locks and loads of storage we can get to site with all the gear safer and more efficiently. 

The A-Team rear spoiler and Mr-T gold chains are on the order list

Know where you stand


Understand ground conditions before you design and build. Establish site class, identify seismic hazards and liquefaction risk. RDCL apply in-situ ground testing, advanced geophysics coupled with insightful geology and engineering knowledge to reduce risk to assets, avoid over-engineering and reduce insurance costs. 

Take a look at some of our recent projects

Get the full picture

RDCL provide detailed geophysics to extend the value of your drilling and sampling. Our geophysicists get out and dirty to acquire the data, and work with our geologists and geotechnical engineers to interpret it and give you the answers you need. We work with developers, contractors, structural engineers and others to add assurance to large-scale construction projects and save you money on problems you didn't see coming

Here's an overview of our capability

The right people - and the right tools - for the job

RDCL have a significant investment in special people and specialist equipment. More importantly, we have the in-house resources to interpret geophysical data and provide you with meaningful advice. We have built a smart, mobile team of engineering geologists, geophysicists and geotechnical engineers who understand real-world construction and development issues.
