Our proven capabilities

Over the last 30 years we have worked on many major projects, both locally and internationally to expose the value of land and groundwater. We have successfully assisted in the remediation of land, creating a cleaner, greener earth for future generations.


When land needs to be nurtured, repaired, sustainably utilised or its value unlocked, our name should be foremost in mind. We are committed to producing scientifically sound work that offers our clients the best value.


Since 2002 we have been restoring the value of contaminated soil and groundwater resources, using unique scientific based solutions. Our mix of established practices and innovative solutions assists our clients in meeting the various strict environmental regulatory controls that are in place.


As a solution focused business, we strongly believe in investing in research and development. Our research team works tirelessly behind the scenes to innovate and commercialise the most sustainable methods to deal with contamination.
