This is a circular concrete made out of dredged sediments. Dredged sediment is a muddy waste stream from our rivers and canals. Dredge currently knows only low value applications, although it causes high costs, a lot of CO2 emissions and wasted time.

By applying dredge in a circular concrete, Waterweg makes sure it can have a high value application. Because of the use of a waste stream and the low energy production process this product can get up to 50% CO2 reduction compared to conventional concrete. Waterweg aims to apply this material in holistic products that contribute to a climate adaptive and future proof city, of which their water passing tiles are the first of many products to come.
