About Subcon

Subcon is a global provider of engineered reefs, marine foundations and seabed stabilisation services. At Subcon, we believe in engineering for the good of marine economies and eco-systems. This means on every project, we work to reduce our carbon footprint and to maximise the benefits our solutions provide to our clients and the environment.

Subcon solutions are engineered to maximise habitat value, reduce inefficiencies in installation and deliver optimal operations. We don’t set out to reinvent the wheel – but if we see current processes in need of improvement, we’ll innovate solutions that promote thriving ocean communities.
