A series of concrete blocks with a difference are appearing on the waterfront overlooking Plymouth Sound.
Five BIOBLOCKs have been deployed on the coastline at Teats Hill, close to the University of Plymouth’s Marine Station and the National Marine Aquarium (NMA).
Constructed by Brixham-based ARC Marine, they are designed to raise awareness of the potential benefits of artificial reefs in the marine environment.
Researchers at the University are involved in a number of schemes using designs different to the standard smooth concrete normally used in coastal infrastructure as a means of improving biodiversity along our coastline.
Now they are working with the NMA, ARC Marine and Plymouth City Council to incorporate some of those measures into the wider regeneration of the Teats Hill foreshore.
The BIOBLOCKs, funded by the Marine Institute thanks to Higher Education Innovation Funding (HEIF), are now in situ on the Teats Hill foreshore.
Each measuring a cubic metre and weighing around 2.4 tonnes, they feature a range of holes and depressions designed to replicate a rocky intertidal area. Normally, they would replace boulders in groynes, breakwaters and other rock armour structures, but have been specifically positioned by the slipways at Teats Hill so they can be observed by the public.
