Protecting your projects undergound assets..

We are a progressive Sydney based business, specialising in handling non destructive vacuum and hydro excavations. NDEA coined the term non destructive excavation almost a decade ago!

We appreciate that underground services can pose huge risks to any construction project. Gas, power and telecommunications lines are everywhere. Many contractors believe that the dangers presented by these risks are acceptable occupation hazards. But here at NDEA, we’re trying to change that mindset.

Hence we successfully locate all the underground services on your site while keeping the environmental impact to a minimum.

NDEA are proud of its cost effective and safe vacuum excavation procedures.

Whether its optical fibre, gas lines, sewer pipes or water pipes, etc. our expert team of professionals delivers timely and effective identifications for all underground infrastructure.

The Process

Using our huge 4500 litre sludge tanks along with 2500 litre capacity water tanks, we can take over and deliver the most difficult of jobs on time.

Pressurised water is used to loosen and remove soil. A vacuum source makes sure that all the excess water and soil is promptly removed from the site making sure that the underground infrastructure remains intact and clearly exposed. This earth is then stored in our self contained trucks to be removed.

We are able to locate pipelines, phone lines and fiber optics, in fact anything that may be buried under ground. Our usual digs are 0.8 to 2.2m underground, but if the need be, you can count on NDEA to dig whatever is required.

Our operators are trained, responsible professionals who work safely and efficiently. Our work is always ready to be inspected and we make sure that if further work is required we will deliver timely results.
