Regional and Council Projects

Many existing council ventilation shafts are now in excess of 60 years old and present an urgent safety risk to people and property. Concrete cancer and sewer gases attack the vent shaft and expose the reinforced steel bars, making concrete vent shafts susceptible to lightning strikes, collapse and the risk of causing serious injury.

Vent shaft replacement is the best option for public safety, with no ongoing maintenance costs.

We specialise in:

  1. Removal, disposal and replacement of aging and deteriorating vent shafts for regional councils and water agencies
  2. Difficult vent shaft access e.g. residents’ backyards, working near roadways, overhead power lines and underground services
  3. Detailed design advice, odour/gas assessment and condition assessment of existing vent shafts, helping you plan your maintenance budget
Interested stakeholders

Community relations

Since the majority of vent shafts are located on private property and in residents’ front and backyards, our first priority is to communicate with property owners.

We liaise with other interested stakeholders including neighbours, local councils, government organisations, developers and private businesses.

Where the work has a high impact on the wider community, we assign a site-specific Contractor Community Liaison Plan.
