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 and access to a range of technologies and approaches is required to be able to deliver the most effective solutions for both new and existing (retrofit) VMS building projects. Coover has completed projects ranging from a 400m2 residential house up to a 6,000m2 shopping centre complex.

Fast, Cost-Effective, Verifiable Solutions
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.
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:

Globally Sourced Solutions
Where required Coover also provides ongoing VMS Operation Maintenance and Monitoring (OM&M) support to ensure all VMS installations commissioned by Coover work efficiently and effectively for the designed life of VMS. This may include annual VMS inspection checks of passive venting systems to ensure all exhaust vents and air intakes are clear and in good working order to more sophisticated 24/7 online monitoring of equipment (e.g. fans, alarms, sensors etc) on high risk sites which require higher levels of operational performance and compliance. In all cases we work closely with the managing Owners Corporation/Facility Managers to ensure ongoing monitoring requirements can be implemented efficiently and cost effectively.
