Boskalis Environmental is a global leader in large-scale environmental remediation of contaminated soil and dredged sediment. We conduct waterbed remediation by processing dredged material in specially designed mobile separation and dewatering plants. We also construct permanent sediment treatment plants. In addition we can provide extraction of building materials from waste for re-use. Boskalis subsidiary Cofra has patented techniques for sealing contaminated soil, extracting landfill gas and compacting material to reduce volume.

Cost-competitive soil remediation and beneficial re-use

Around the world, there is a growing demand for large-scale remediation solutions for contaminated soil located on land as well as underwater. This remediation is often part of land development projects that are time critical, subject to strict environmental requirements, and where costs are a major feasibility factor.

Involve us early on to help guarantee an accurate and comprehensive response to complex issues.

Boskalis has extensive experience delivering complex projects worldwide. We manage the entire process for you – from inspection and design through to the implementation of remediation work, transportation and disposal at re-use sites or depots.
