Stream 5B: Eco Armouring

Moderator: Caroline Barford, Coastal Partners, UK

Question – Diccon Rogers, KLM: Is it fair to say that the concrete eco enhanced structures are only really going to be deployed in more benign environments, and when I say more benign, I contrast it with the very aggressive degradation tests we have to meet when we deliver rock armour. If you think we do drop tests, which is an extremely aggressive form of testing - dropping rock from three or four meters onto a pre prepared anvil, we do everything we can to really stress our rock, I would venture to say that the structures that you’re promoting probably wouldn’t pass that drop test, or all the other aggressive degradation tests. So just a question, really, will they ever be as rugged as rock armour?
