Landfill Quality Assurance
Terra Firma’s expert landfill consultants deliver detailed inspections, verifications & quality assurance while considering the environment footprint. Our consultants have extensive experience securing landfill quality assurance in new cells for EPA licensed landfills across Australia.
We place experienced CQA Engineers onto construction sites so that the validation work is carried out accurately and effectively. We have significant experience of all types of lining systems and the CQA procedures to verify them.
The duties of the third-party CQA consultant(s) will include:
- Inspections
- Verification
- Audits and Evaluation of the materials and workmanship
- Provision of advice on the interpretation of the drawings and specification, including installation, testing, repair and covering of the critical aspects of construction (not design or contractual advice); and issuing a final CQA Validation Report documenting the quality of the constructed facility.
Associated works are done in accordance with the Australian standards

Our Process
The process for a client engaging with a Landfill Construction Quality Assurance (CQA) company typically involves several stages. The goal of the CQA process is to ensure that landfill construction activities comply with regulatory requirements, environmental standards, and engineering specifications.
Throughout this process, effective communication between the client and the CQA company is crucial to address any concerns, changes in scope, or unforeseen challenges that may arise during landfill construction

Electrical Leak Survey
The geomembrane you use in your project undergoes extensive quality assurance during the manufacturing stage to verify the physical and chemical properties against the project specifications and internationally accepted best practice guidelines. However, there are number of factors that can damage the geomembrane and cause it to leak. Therefore, the leak detection of your installed geomembrane prior to use is extremely important and mandatory within most jurisdictions around the world.
A leak can be an invisible 0.5mm pinhole or a 2-meter tear under the cover material placed on top of the geomembrane. Our team uses internationally recognized electrical leak detection methods to find the defects on your geomembrane to give you the confidence of a leak proof liner system and to help you obtain the licences and approvals.
Why is this required?
You may have a leak in your dam or landfill you need to find where it is to repair. A leaking liner can cause a whole lot of structural and environmental issues for your operations
