For the reclamation of the new Invergordon Phase 4 service port, BONTRUP delivered over 200,000t of Widegrade® material, which was used as revetment dyke around the reclamation area.
The material was delivered directly to the project site by self-offloading conveyor belt vessels. The use of Widegrade® as revetment ensures a stable structure, also when exposed to currents and waves during construction.
Due to its unique grading it provides a stable filter, allowing direct placement of fine (sand/silt) backfill material without the need for a geotextile layer.
