The Boskalis Dolman bv laboratory focuses primarily on supporting the soil washing process at Boskalis Dolman bv itself. The laboratory also provides back-up for the activities of Royal Boskalis Westminster nv, both in the Netherlands and abroad.

The laboratory's activities include soil and waterbed surveys during preparations for project tenders, the monitoring of process quality during a project, physical analyses of soil and bed material, and setting up 'project' laboratories on site. Two members of staff have been certified to conduct environmental soil surveys in accordance with BRL2000 (protocols 2001 and 2002).

As well as conducting physical analyses, the laboratory also maintains good contacts with external chemical laboratories and research firms for the purposes of soil surveys and a wide range of analyses. This means that the laboratory can provide full support.
