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
