During 2020–24, two new hazardous waste disposal sites were built for the waste management company Vestia in Ylivieska. The total area of the sites is about 50 hectares.
First, the old soil was removed from the sites and rock was excavated. After this, a sealing layer was built out of clay. Finally, a plastic film was installed on top of the clay layer. This effectively prevents harmful substances from entering the soil. Earthfill embankments were also built around the disposal sites.
“Our cooperation with Sundström was smooth – the low hierarchy on the construction site and the ease of reaching agreements surprised us positively. Sundström excellently tackled the challenges posed by the project’s tight schedule. In this kind of weather-dependent land construction project, Sundström’s clear strength is the good availability of equipment.”
