In 2012 the Dutch government introduced the Hillblock for the first time in her sustainable revetment project; Stavenisse.
Due to the shape of Hillblock 30 percent less concrete is needed to reach the high requirements of stability of Rijkswaterstaat.
After a year of extensive monitoring the pilot status of Hillblock in Stavenisse was converted into the status of established project.
RWS was rewarded for the Sustainable revetment project ' Stavenisse polder'

Rijkswaterstaat aims to improve the sustainability of
infrastructure projects and aims to reduce energy
consumption in 2020 by 20 percent compared to 2009.
Rijkswaterstaat uses four instruments to achieve this goal:
the ‘Omgevingswijzer’ (‘Context Appraiser’); DuboCalc LCA
software; the CO2 performance ladder and a tendering

Rijkswaterstaat’s contribution to the government policy

collaborates closely with all partners, customers and clients
in the civil engineering sector to make the sector more
sustainable in a partnership called the ‘Green Deal
