We are interested to note this piece from the Eastern Solent Coastal Partnership website. Parts of the sea defences on the Warblington shore line, compromised during last winter’s storms, have been effectively repaired using a new technique.
The repairs commenced on 1st August 2018 to the worst damaged sections of wall, where the concrete rendering had detached itself from the main wall structure and was laying on the foreshore of the harbour. The works were delivered by ESCP and were carried out by contractors Graham Attrill Civil Engineering Ltd., from the Isle of Wight on behalf of Havant Borough Council.
Within two weeks the works were completed using an innovative material called Concrete Canvas, used by Havant Borough Council for the first time. The Concrete Canvas was delivered to site as a roll of concrete impregnated fabric, which was cut to length and draped over the wall, allowing the fabric to follow the contours of the internal wall beneath. Once in place, the fabric was sprayed with freshwater to activate a concrete fibre embedded within. The concrete fibre forms an impermeable, energy absorbing concrete casing, perfect for withstanding wave action. The material repaired the seawall and will protect the internal structure from further erosion.
Following completion of the works, ESCP staff will continue to monitor coastal structures within the harbour on an annual basis. This will help inform any future works and allow ESCP to identify changes in structure condition within the HBC borough.
