Application areas

Cofra provides integrated solutions for many ground improvement and specific environmental markets. We cover all project phases related to ground improvement from (pre-) feasibility and design through to construction and monitoring. We can offer together with Boskalis comprehensive solutions (quay walls, roads, railways, tunnels and bridges) and have together almost over a century experience to accommodate it.

Our Markets and Application areas

Csm IMG 7687 4Ede827051

Infrastructure: roads, railways, ports, airports

We provide solutions for the consolidation and compaction of the subsoil in order to reduce post construction settlements and guarantee stability during construction. Our barriers can be used to create the line infrastructure below ground water level.

Makassar CVC 77

CDC, CRC and CVC compaction for new reclamation for the expansion of Makassar Indonesia

We compacted 450,000 m2 land reclamation using our compaction techniques. The uniqueness of this project was that three compaction techniques were available for the compaction of the reclamation of up to 12m thickness. This made that optimisations were reached in the deployment of the techniques.

Dover_1

CDC compaction for DWDR project in Dover, UK

We compacted in 2017 in several phases 90,000m2 for the expansion of the Dover Western Harbour Front. Compaction was executed right next to sheetpile walls.

Saa-One_172

CDC compaction for carriageway railway bridge

We compacted in several phases the carriageway for the transport of a 13,500ton railway bridge in 2016. Compaction was executed in strict time schedule due to closures of highways for the compaction of the subbase material.

Felixstowe2_36

CDC compaction for Felixstowe berth 9 expansion

We compacted in two phases the new berth 9 quay  in 2015 and in 2018 the remaining area behind the quay.

CDC compaction for Gabon Fertilizer plant

We compacted 540,000m2 for the Gabon fertilizer plant in Gabon in 2013 using 3 machines.

DSC_9020

CDC compaction for Antwerpen East port

We compacted 80,000m2 for the development of warehouses near Antwerpen, Belgium.
