Mine subsidence Survey Services
Professional Mine Subsidence Survey Services in NSW:
If you’re building or developing in an old mining area, mine subsidence is something you can’t overlook. We help you navigate the risks that come with developing on land that’s been affected by historic or active mining. If you’re planning a subdivision, a new build, or a major infrastructure project, our team works closely with you to make sure your plans stay safe and compliant from the ground up.
What is a Mine Subsidence Survey?
Mine subsidence is when the ground dips, shifts or sinks because of old tunnels or voids left behind from mining underground. It might happen suddenly, or slowly over the years, either way, it can put buildings, roads and even people at serious risk. That’s why parts of NSW are mapped as mine subsidence districts, to make sure any development in these areas is properly assessed and built the right way.

They were quick to respond to my inquiry and quick to provide a quote. Once I approved the job the turnaround time was amazing. Great communication and very helpful to deal with. Highly recommend, very competitive pricing and would definitely do business with them again. Peter Buffington27/08/2024Trustindex verifies that the original source of the review is Google. CEH Consulting helped us during a first time doing a house construction and subdivision. All the staff were great but Matt Smith in particular carried out all of the required surveys, redefinition plan, CDC approval, land title paperwork etc. very professionally and in a timely manner. He also offered general advice that looking back really helped us in the process as it's a bit confusing if you haven't done it before. We definitely wouldn't have gotten the project wrapped up in the timeframe we did without Matt and the CEH team. Would highly recommend. Federico O24/06/2024Trustindex verifies that the original source of the review is Google. Greate and professional service! Highly recommend CEH.
