Beachville Seawall

The construction of a new seawall on Beachville Road in Redcliffs was a demanding SCIRT project which won praise from residents and the construction industry alike.

Enhancing the coastline along Beachville Road in the Christchurch suburb of Redcliffs is an elegant riprap revetment seawall built to protect the coast from erosion and local residents from flooding and storm surges.

The modern earthquake-resilient structure replaced a more than 100-year-old vertical seawall which was no match for the seismic forces unleashed by the February 22, 2011 earthquake.

Local residents along the seawall took a huge interest in the SCIRT rebuild project and shared the journey each step of the way as the coastal defence was built in stages along a half kilometre section of Beachville Road during late 2015 through until August 2016. In the process, several thousand tonnes of rocks were employed, and around 40,000 square metres of geotextile.

Local company Seipp Construction, contracted by SCIRT to build the seawall, won the 2016 Canterbury Contractor of the Year Award, for a project in the $1.5 million to $5 million category, for the expertise and capability it demonstrated on the challenging job.
