Sustainable Waterways

When we plan your stormwater project, we plan to protect your water quality.

Stormwater infrastructure is vital transport networks for drainage and have a significant impact on the amenity and liveability of the communities we serve.  When we plan stormwater works, we consider a range of methods and select the best solution for that specific site.

Critical to our stormwater management process is maintaining an optimum flow to keep streams, lakes and aquatic life healthy. This process also supports water used by people and communities, enabling a natural flow cycle which prevents infiltration, flooding and erosion.

Sustainable waterways for generations to come

We are experts in construction, pipe lining, relining, sealing, coating, repairs and maintenance of stormwater assets. Our partnership will ensure your stormwater assets are managed throughout all stages of the project – from initial consultation, planning and design through to construction and maintenance.

Our teams are qualified to inspect, assess and renew even the most degraded stormwater pipes and will work around-the-clock in the most critical situations to ensure your project is delivered to the highest quality. Our extensive range of services includes our patented spiral-wound liners, that enable us to repair stormwater pipes, whilst maintaining flow capacity. This avoids the need to decommission existing lines or excavate roads, making your projects more time and cost efficient.

We deliver elegant solutions for all your culvert needs

Since our inception, we have been providing our customers with essential pipeline infrastructure solutions for roads, rails and bridges. Our expertise in this field enables us to offer end-to-end solutions for the understated but essential pieces of infrastructure that support our transport networks – culverts.

Our culvert delivery solutions cover every stage of your project: from planning, design, construction, renewal, and periodic maintenance – all factors are considered when managing your culvert assets.

We have an extensive range of trenchless culvert renewal solutions to renew culverts, including corrugated metal and box culverts, which can be tailored to a range of diameters and ensure minimal loss of diameter.
