Precision Mine Subsidence Survey Services. Fast Turnaround. Zero Guesswork.

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.

What We Do for Mine Subsidence Survey Projects
If your site’s in a mine subsidence area, you’ve probably already realised things can get complicated fast. That’s where we come in. Here’s how we help:
-
Risk Assessments
We take a close look at your site to figure out if there are any actual risks tied to past or current mining activity. No guesswork, just solid, practical insight based on the facts. -
Dealing with Subsidence Advisory NSW
No need to spend hours emailing government departments. We’ve done this plenty of times, so we’ll handle all the coordination with SANSW and make sure your paperwork’s sorted without the usual drama. -
Reports & Advice Before You Build
Before you even pick up a shovel, we’ll give you the lowdown on what you need to know. That includes site-specific reports and practical advice to help your builder or architect design something that won’t cause issues later. -
Fixing the Tough Stuff
If your land’s already been affected by subsidence, we’ll work with your engineers to sort out a proper fix. Whether it’s stabilising the ground or putting mitigation measures in place, we’ve got your back. -
Surveys to Keep You Compliant
We’ll get on-site when you need us, mark things out, and give you all the compliance survey data you need to satisfy councils or SANSW. Quick, accurate, and ready when you are.

TESTIMONIALS
We will definantly be using them on all our projects going forward.
My wife and I are based on the NSW South Coast and have used CEH Consulting for surveying work. Unlike some of the other local surveyors we approached, Matthew provided a quote for the work quickly and the quote was really fair and reasonable.
Once we accepted the quote, the team was on-site shortly after and the surveying was completed a lot faster than we expected. The surveying team were very polite and courteous, and easy to deal with.
The surveying plans/documents produced were spot on, with no issues. When I had to drop off the signed documents to the CEH office (while wrangling a very grumpy two-year old!), the reception staff were wonderful and really helpful, even getting the door for us on the way out.
Throughout the entire process, Matthew and the team were responsive in their communication and very efficient. With Matthew's experience in the industry, he was able to guide us along the way, which was greatly appreciated given our inexperience.
Overall, for anyone undertaking a subdivision/development and seeking quality service, we could not recommend CEH Consulting more highly. Thank you for a hassle-free experience
