Precast concrete plays a crucial role in protecting New Zealand’s coastlines, offering a durable and resilient solution for managing erosion, wave impact, and rising sea levels. Its inherent strength and long service life make it an ideal choice for safeguarding vulnerable shorelines, public spaces, and essential infrastructure — all while minimising ongoing maintenance.

Preco manufactures precast coastal protection elements that are engineered to withstand harsh marine environments and perform reliably over decades. These solutions not only help preserve natural landscapes but also protect habitats vital to local wildlife and ensure safe access for communities who live, work, and play by the coast.

From seawalls and wave deflectors to bespoke armour units, our team can provide tailored design input, practical constructability advice, and high-quality precast components that support environmental, community, and ecological resilience. If you’re planning a coastal protection project, we’d be happy to discuss how Preco can assist.
