In the summer break window of 2020, PEC Zwolle decided to convert their synthetic turf playing surface to natural grass. The Dutch Football Association requires clubs that play at the highest professional level to be able to keep their fields free of frost and snow in wintertime. It was therefore decided that installation of an undersoil heating system would need to be included in the project. SPS was awarded the contract to supply and install the pitch pipes matrix because of its expertise and very tight construction deadlines.
