Inland dredging

Carrying out dredging work

To ensure the continued optimal use of waterways, harbours, estuaries, lakes, ponds and sand extraction pits, professional dredging is essential. Timely dredging maintains water depth and prevents blockages and silting. This ensures that an area remains not only accessible, but also safe and sustainable in the long term.

As a Dutch dredging company with more than 35 years of experience, we specialise in executing dredging projects. Over those years, we have grown to become a reliable partner for both small-scale and complex inland dredging projects, wherever quality, flexibility and innovation are key. Our expertise includes, among other things, the following activities:

  • Cleaning up sites by removing vegetation
  • Dredging
  • Pumping and transport by water (using hopper barges),
  • Shredding and/or screening of dredged material, such as:
    • sand
    • sludge
    • or other vegetation in waterways, harbors, estuaries, lakes, ponds, and sand extraction pits

Specialists in dredging at hard-to-reach locations

Not every location is suitable for standard equipment. This is precisely where our strength lies. We conduct dredging activities in places where other equipment such as tracked dumpers, tracked excavators and suction dredgers are unsuitable. We carry out our work in areas that are difficult to reach or access such as:

The dredging equipment we have developed in-house enables us to work efficiently and safely in these challenging conditions. Examples include amphibious excavators and DOP submersible dredge pumps, which allow us to dredge effectively even in vulnerable or hard-to-reach areas.

From advice to implementation

A comprehensive range of services for your dredging projects

A successful dredging project starts with thorough preparation. That is why we carefully consider the best approach right from the start. From consultancy and project preparation to the full execution of dredging works, we offer a complete service. We supply a comprehensive solution that matches the specific situation and objectives of the project. Electric dredging is now also possible.

We also provide support on sub-projects and dredging equipment rentals. This allows us to move quickly and deploy tailor-made capacity when needed.

Areas of Application

Our activities are wide-ranging and highly versatile. Because of this versatility, we are able to provide a suitable solution for any dredging-related issue. These activities can be applied in a wide range of projects, such as:

  • Cleaning or clearing excavation pits
  • Pumping out ships’ holds
  • Dredging in sand extraction pits
  • Work in lignite mines (for example, for the construction of solar farms)
  • Maintaining and restoring lakes, ponds and recreational areas
  • Dredging in harbours and estuaries
  • Trenching for cables and pipes
  • Installing silt screens
  • Transporting dredged material, peat, silt and sand
  • Pumping dredged material to disposal sites

Together for a better water environment

Dredging equipment and rental options at Knoop BV

We use a modern and versatile fleet of equipment to carry out our projects, from amphibious excavators and modular pontoons to dredging pumps, workboats and pipeline systems. This versatility allows us to work efficiently in a range of conditions.

In addition to use on our own projects by our dredging company, the dredging equipment is also available for rental. This allows us to offer reliable and well-maintained equipment, tailored to the specific requirements of the project.

Combining different types of equipment for a suitable solution

No two dredging projects are the same. That is why we work not only with standard equipment but also with smart combinations of specialist equipment. By deploying machines, pumps, pipes, hopper barges, workboats and complementary technologies in a modular way, we are able to put together the most efficient solution for each project.

A good example is our screening dredger. It arose from a specific project requirement, which called for a combination of dredging and on-site separation. By integrating existing technologies into a single working solution, we were able to make the process significantly more efficient and sustainable.

Amphibious excavators (2 to 35 tonnes)

Specially developed for working in low load-bearing areas and hard-to-reach locations. Thanks to their amphibious undercarriage with low ground pressure, they can dredge efficiently on land and in water

DOP pumps (submersible dredge pumps)

Powerful submersible pumps for pumping sludge, sand and other dredged material over longer distances. Ideal for hydraulic dredging in combination with floating pipe and HDPE.

Shredder Dredger

Developed in-house for shredding coarse materials and vegetation in water and pumping them to the disposal site.

Screening Dredger

Developed in-house, combines dredging, screening and processing in one pass. Separates coarse particles (such as wood or plastic) directly from the dredged material, making transport and processing more efficient.
