Coastruction's technology comes with freedom of material

FREEDOM OF MATERIAL

Sustainable use of natural resources

Coastruction's technology comes with freedom of material. This literally means the possibility to use any type of liquid binder with similar viscosity of water, any type of cement and any type of granular fill material. 

 

The combination of these three parameters allows us to print a lot of different recipes. We can 3D print with seawater or local fresh water and with respect to cement we can use limestone or different varieties of Portland cement or any other type of cement. The selection of fill material is probably the widest, ranging from common local aggregates, such as sand from the nearest beach or the seabed, dredged material to even recycled concrete.

WORKING ON-SITE, USING LOCAL RAW MATERIALS

Sustainability for us begins with the use of natural, and ideally, local materials. We are not a big fan of chemical additives to bind the material and therefore we don't use them. For us, au naturel, works just fine. 

The use of regionally extracted raw material optimizes the supply chain by shortening transportation routes and reduces harmful emissions to the environment. Subsequently it has a big positive impact on the project budget.

Lowering CO₂ impact

Global warming has strongly contributed to the reduction of coral reefs worldwide. The production of cement is the 8% cause of CO₂ pollution. It is therefore our goal to make any structures we print CO₂ neutral.

 

We have come a long way, but we are not there yet. Our production process has a number of advantages positively impacting the footprint and the environment.​ We foresee a huge interest in the re-use of (construction) material in combination with innovative technologies such as 3D printing. The process of making concrete is irreversible. The only way to reuse concrete is by using it as a filler. Our technology allows this.
