Culverts are a crucial part of infrastructure across New Zealand, offering a fast, reliable, and cost-effective solution for directing water, supporting traffic, and managing stock movement. Their inherently strong structural form allows them to withstand a wide range of loading conditions, while their rapid installation minimises disruption to surrounding environments and road networks.

Preco manufactures culverts in standard 500mm size increments (internal measurements) as well as fully bespoke configurations, with dimensions typically ranging from 1.5m to 5.0m in both span and height. Lengths of up to 2m can be produced, with optional features such as fully watertight joints, rebated or flush connections, and customised design enhancements.

Our team can provide full design and constructability advice to ensure you receive a solution that is efficient, durable, and tailored to your project requirements. If you’re planning a culvert installation, we’d be happy to discuss how Preco can support your next project.

Additionally, through our Post Tensioning division, Post Tensioning & Grouting, we can offer longitudinal stressed and grouted solutions to further enhance performance and structural efficiency.
