Over many years we have developed specialised know-how in making calculations and designs for noise barriers. With the arrival of the HSR in the Netherlands and a number of other large infrastructure works, the number of projects for this discipline has grown significantly, adding to our experience. We can take care of the entire range of composition (elements, styles, rails, foundations, cantilever beams, etc.) as well as elaborate specifications (alignment drawing, pile planning, list coordinates, element drawings, etc.).
