Failure of defences
6th April 2018
Works have continued to progress well down on site. The sheet piles have now been driven to required depth and the tops cut down to the correct level. Structural fill has been placed and compacted behind the sheet pile wall, ready for concreting and resurfacing.
200 tonnes of rock armour have been placed in front of the sheet piles and covered over with beach material. The rock is designed to reduce wave energy, protecting the area in front of the piles and will stabilise the existing beach. The rock is Purbeck stone from Dorset and each one has minimum weight of 1 tonne!
We have also begun bringing in material to help replenish the beach, and nearly 150 tonnes has been placed so far. The shingle is of a similar size to what is currently on the beach and is locally sourced from the Solent.
Next week we are planning to continue to bring and place beach material, with 800 tonnes ordered in total. The concrete slab will be poured on by the end of this week, and the capping beam the following week.
