Innovative Solutions

We recognise that sole use of conventional vapour barriers, membranes and liners address only part of the problem. A more holistic integration of science, engineering, building construction, emerging Vapour Intrusion technologies and materials, Construction Quality Assurance (CQA), independent certification and ongoing monitoring is required to be able to deliver world’s best practise vapour mitigation solutions for both on-ground and basement inclusive buildings. Coover has completed projects ranging from a 400m2 residential apartment complex up to a 6,000m2 shopping centre complex.

Customised Design

Innovative thinking, science/engineering expertise, high level construction techniques using a suite of vapour mitigation products and technologies sourced from around the world, enables Coover to deliver exceptional solutions and outcomes for our clients whilst delivering safe and enjoyable urban living spaces for the wider community.

Our unique ability to offer the full suite of vapour mitigation solution services enables Coover to control all aspects of the project so we can deliver reliable, verifiable, cost-effective, and timely solutions for our clients. We work closely with the project’s appointed architect, builder, civil contractors, assessor and EPA to ensure there is seamless integration of the VMS into the construction program and final building form and function.

During construction, our work is regularly checked and independently verified, and on completion of works we comprehensively test and commission the entire VMS. Our service delivery is of the highest standard and regularly endorsed by EPA Auditors.

In order to deliver the best solution for each unique vapour intrusion situation, Coover applies the following a 5-step process:

Coover’s Proven 5-Step Process
