Gebr. Van Leeuwen mainly works with exclusive in house developed equipment. An important advantage besides the high quality is that it allows us to interchange TBM’s and equipment, enabling an ideal combination of components for each project. All our equipment is periodically maintained and inspected in accordance to mandatory standards.


Using our own microtunneling equipment Van Leeuwen Sleufloze Technieken installs pipes ranging from 400 mm up to 3000 mm in diameter. All known pipe types such as steel, concrete, fibreglass reinforced, and polymer can be used. Other materials are also possible, for example plastic pipes to ensure a safe disposal of liquid waste from laboratories.

A major advantage of the microtunneling technology is that it can be carried out ‘in the wet’, meaning without having to disrupt natural groundwater levels in the drilling area. If dewatering of the start and ending shafts is not an option, a sheet pile construction in combination with an underwater concrete floor provides an ideal solution.
