During the construction of the large infrastructural projects like the HSL (High speed train). Because the line has several tunnels under the main rivers and canals, the state office for infrastructure in the Netherlands have relied heavily upon  camera’s from Tecson Inspections for assuring quality or locating the reason of problems.

An example of a special inspection in this area is done during the filling of the last vow at the inside of a tunnel. The closing vow is the connection between the land part and the water part and can only be done from the inside of the tunnel.

The camera’s are the eyes for the construction company and will tell them if the vow is completely filled with concrete.

Due to the increase of strict environmental regulations inspection of sewers has become very important during the last several years.

Tecson Inspections and its sister company M.J. Oomen Leidingtechniek are the biggest camera-inspection companies offering sewer inspections in the Benelux countries.
