Project Description

Overview

Part of the English Riviera, Paignton itself was once just a small fishing village. In the mid 1800s, a man-made harbour was built to protect the fishing boats – to this day, it still offers shelter from stormy seas and changing tides. Unfortunately, the sea had scoured and undermined the harbour’s east breakwater, which was now at risk of collapse. Our brief was to shutter and concrete a section of the concrete wall.

 

Challenge

This project presented several key challenges in terms of exposure to the elements and location. First, we had to carry the work out during the largest spring tides of the year. Access was poor, so we had to carry all materials and equipment down to the bottom of the wall. Finally, to minimise potential contamination risks, we needed to use additives in the concrete mix – which we then pumped over the breakwater to fill the pre-constructed shutters.

 

Result

Despite a limited working window of three hours each tide, we were able to complete the work within five days. The new section of concrete wall now underpins the existing wall and offers protection from further scour and undermining.
