GMB is a versatile family business. We realise and / or renovate, among other things, dikes, harbour areas, sewers, pumping stations, water purification installations and sludge processing installations. We also process sludge from wastewater treatment plants in our own processing plants. For our clients - ranging from government organisations  to businesses - we are a partner with whom they enjoy sharing both major and minor challenges.

Six clusters

In recent years we have developed an organisational structure that is designed for all types of projects and one that is tuned to our competences design & construction, management & maintenance and operation. We offer tailor-made service to our customers. This is possible due to an organisational structure in which six clusters are central:

• GMB Services

• GMB Bioenergy

• GMB Sewage techniques

• GMB Water quality & installations

• GMB Water safety & constructions

• GMB Harbour & industry

400 professionals

We serve five market groups with the six clusters: the Dutch Ministry of Infrastructure and Water Management (Rijkswaterstaat), regional water authorities, municipalities, drinking water companies and industry. More than 400 professionals work hard every day to be of value to our customers and to society. In doing so, we unite strong design and implementation skills with knowledge, innovative solutions and passion for our work. This is characteristic of GMB. Heart, head and hands. This combination enables us to accomplish surprising achievements.
