Our solution combines innovative technology, natural materials and the concept of circular economy.
We use cement in a sustainable and circular process to create beautiful, complex structures using 3D printing powder bed technology.
Coastruction’s mission is to restore reef systems, protect coastlines and inspire people to achieve a sustainable relationship with marine ecosystems. In our work we collaborate with as many parties as possible. The condition of the reefs simply demands large-scale solutions in order to be effective.
This can only be done through collaboration.
3D printing powder bed technology allows the user to create any form imaginable while at the same time providing the freedom of material. The result is a concrete structure that combines habitat preferences of multiple species in a sustainable production process.
Marine reef systems are essential to humans.
We feed from them, we are protected by them and we breathe through them. We work with them study them and enjoy them while diving or snorkelling.
Coral reefs are under enormous pressure. 50% of coral reefs worldwide are already dead and >90% of coral reefs will likely die by 2030.
And with corals dying, the complex system they belong to also deteriorates. Rising seawater temperature, bleaching events, overfishing and pollution are threatening reefs at a higher pace than we can imagine. When corals are gone, beaches erode, fish populations decrease, and many low-lying places will suffer from flooding.
We can print site-specific structures that cater to the needs of local species. With our 3D print technology, we can create any shape imaginable. Without anything other than water, limestone and sand. We believe that in order to create successful artificial reefs, habitat requirements of key species should be taken into account. If there are hiding spaces for herbivorous fish, the structure will be less overgrown with macro-algae and if there is habitat for damselfish, corals might be attacked less often by predators, nutrient concentrations in the water around the corals are enhanced, and both tissue aeration and water flow between coral branches through their swimming actions will also be enhanced.
When we 3D print artificial reefs, we print habitat for all these species, taking into account their specific needs.
No additives are needed in our process.
We use local and natural materials like (sea)water, cement or limestone and local aggregates, such as the sand from nearby beaches or the seabed. No additives are needed in our construction process.
Sustainable and Circular
3d Printing with powder-bed technology allows freedom of form. The powder-bed supports complex shapes such as arches and spheres. The process is also free of moulds and waste. Unused cement can be reused and so are excessive reefs. We further reduce emissions by printing onsite. We transport the printer instead of the reefs.
Freedom of Shape
Mesmerizing structures inspired by biomimicry (the emulation of the models, systems, and elements of nature for the purpose of solving human problems) that cater for a plethora of species: the application of innovative technology, joining forces with people that care for our oceans and trying to make the world a better place. That is Coastruction!
Coastruction is contributing to the Sustainable Development Goals 12, 13 and 14.
Help us save the reefs, let's start printing!
