Bespoke Seawalls

The Tupua Horo Nuku project involves the construction of a 4.4 kilometre walking and cycling path along Marine Drive between Ngau Matau (Point Howard) and Eastbourne in the Wellington region. The path will provide a safer route for those walking and cycling in the area, encouraging these active modes of transport which will in turn help reduce congestion and improve health and wellbeing, as well as better connect local communities between the bays. A new seawall is also being built along the corridor which will be the platform for the path and improve the resilience of Marine Drive by providing protection against storms and waves, along with coastal erosion.

Hynds has manufactured the unique seawall units, with each unit measuring three metres long and including high strength 50MPa concrete and galvanised reinforcing. Manufactured at our Palmerston North site, the new seawalls will not only provide protection from surge and waves, but also enable the Marine Drive corridor to respond to the challenge of climate changes and sea level rise, ultimately helping to protect the road and essential services for local communities.

The seawall units have also been designed to allow sea life to thrive with a Reckli liner. The curved surface on the front of the units has an architectural pattern cast into the unit. The design not only looks impressive, but creates a 29mm deep roughened pattern that will help provide a natural habitat for sea life.
