Den Herder Seaworks supplies a variety of natural mineral products.
It sells these products directly to clients, or operates under subcontract as an extraction service.

When operating from its own dredging areas on the Dutch continental shelf, the product is mainly sea sand, in a range of particle sizes. When under subcontract as an extraction service, minerals (sand & gravel) can be screened and/or desalinated according to the client’s needs. These products meet requirements of directives of the Dutch Building Materials Decree (KIWA BRL 9313), or applicable foreign regulations.

Through our powerful modern technologies, knowledgeable staff, and deep experience, we supply raw materials of the highest, most consistent quality; we always take care to operate in the most economical manner; and we take every precaution to protect the natural environment.
