Roman-style concrete should be used to build the seawall for the planned Swansea lagoon, an expert has warned. Professor Marie Jackson of the University of Utah warns the steel reinforcing a conventional concrete lagoon seawall will corrode after 60 years. Roman concrete sea defences made without cement or steel could last more than 2,000 years. The firm proposing the lagoon said it would use the best modern engineering. But Prof Jackson told BBC Radio 4’s Today programme that Roman-style concrete based on volcanic ash should be considered. It would also produce far fewer emissions of carbon dioxide from cement manufacture.

One nationally significant infrastructure project consisting of a tidal lagoon has so far been given consent, to be built in Swansea Bay. The government appeared to hesitate about endorsing it and commissioned Charles Hendry, former energy minister, to review tidal lagoons generally. His report came out yesterday and can be found here. The report is an enthusiastic endorsement of tidal lagoons. It’s quite long, at 183 pages, and even the conclusions and recommendations run to 19 pages. Dear report writers, please could you number your paragraphs so that people like me can refer to them easily. Thanks.
