Searching for creative solutions for the unruly North Sea is part of our DutchDNA. The unique locations of hydraulic engineering structures that are constantly battered by the elements mean that robust solutions are required. And we have them!
We supply all standard types of armour stone with the usual density of 2,650 kg/m3. We also supply quarry stone with a very high density. Eclogite has a density of 3,200 kg/m3 and Rodense even has a density of 3,700 kg/m3.
What are the benefits of high density armour stone? A thinner layer is sufficient which saves on material. In the event of stone penetration with hydraulic engineering asphalt or colloidal concrete, it means you need less asphalt or concrete. A higher density is therefore interesting both from a financial perspective and the perspective of ENVI.( Dutch for Most Economically Advantageously Tender).
