Eco-engineering of seawalls to encourage oysters and biodiversity in general is gaining interest worldwide. Retrofitting existing seawalls is an option. The Reef Design Lab has been commissioned by The World Harbour Project to provide a range of concrete seawall tiles to research organisations in over 12 countries for testing. We manufacture the unique designs in Melbourne and ship them worldwide. We currently have over 20 different designs and varying shaped tiles for a range of applications such as habitat enhancement and wave attenuation of seawalls, pilings, geotextile sand containers and docks.
