Contaminated Dredged Material: Building Material of the Future? An Investigation into Building Mound

The Dutch Department of Water Management (Rijkswaterstaat) is developing an innovative concept: building mounds (terpen) of dredged material. Terpenor mounds were common in Holland centuries ago: man-made mounds a few metres high that were placed as a protection against the sea.

Dredging Stiff to Very Stiff Clay in the Wielingen Using the DRACULA® System on a Hopper Dredger
Dredging Stiff to Very Stiff Clay in the Wielingen Using the DRACULA® System on a Hopper Dredger

Dredging stiff clay is notoriously difficult. A newly patented system using high pressure waterjets in the hopper dredger's draghead has solved several operational problems. For his description of this innovative technique, the author was presented with a 2002 IADC Award at the PIANC Conference in Sydney, Australia.
