Intertidal reef cubes
Intertidal reef cubes help you to protect what’s most valuable across your coastline, whilst enhancing marine habitats and biodiversity.
Durable low-carbon defence to shield coastal communities and infrastructure, while enhancing marine ecosystems
Shield your coast, build biodiversity
Protect valuable coastal structures and local communities with Intertidal reef cubes, hardy, low-carbon coastal defence structures that enhance biodiversity at your coastline.
Intertidal reef cubes dissipate wave energy and reduce risk of erosion, whilst working in harmony with the natural environment. Their marine-friendly materials and nature inclusive design mean they’re an ideal way to deliver biodiversity net gain for our habitats and ecosystems.
Units can be stacked, tessellated or scattered randomly, making them deal for partial or full replacement of rock armour, breakwaters, seawalls and stepped or sloping revetments.

Testimonials
“Kier have been very satisfied and pleased with ARC Marine throughout the preconstruction and construction stages of the Newlyn Tidal R&D project. ARC Marine have fabricated and delivered exceptional Intertidal reef cube® ECO armour units for the project where all parties, including Kier, the Environment Agency and Atkins, have been very impressed with the quality of finish of the units. Overall a very exceptional service from ARC Marine and would highly recommend.”
“reef cubes® is a unique product that could reach a massive global market. Marine-i has been proud to help ARC Marine develop and test their amazing new approach to marine conservation and in particular, its application to marine renewable energy. Their pioneering products have the potential to improve the health of our oceans for generations to come.”
"ARC Marine are providing 25% of the reef blocks for the Newlyn project. Their blocks offer multi-functional benefits, such as biodiversity enhancing design and low-carbon fabrication. The development of viable alternatives to carbon intensive and non-sustainable solutions such as reinforced concrete, or quarried rock, is hugely important in order to meet the EA’s organisational targets to achieve net zero by 2030. More broadly, decarbonisation of the coastal and subsea infrastructure industry will also provide an important contribution to wider UK pledges on climate change."
“The idea of a carbon-neutral reef cube® that can be used to help rehabilitate reef ecosystems is exciting – we really need to do everything we can to give coral reefs a break”
