After years of noise pollution from a nearby highway, a GroundPlug noise barrier was built for the local residents in Bregnerod in 2019. As general contractor, we were responsible for the technical calculations, production and installation of the GroundPlug foundations and noise barrier cassetts for the 4m high and 525m long noise barrier. The noise barrier now extens from a small lake near the highway bridge to a nearby forest, where the local residents can now take a walk without being disturbed by the noise of the highway.
