<p>The football field has a covering which provides the protection against all weather influences. In this way, the continued growing of grass can be ensured throughout the winter months. A covering construction is used to cover the complete pitch. The space below the cover is heated by a system fitted in the ground below the playing surface. The heat outlet orifices can be sunk into ground so that they do not appear on the playing face. The cover construction can be produced in pallets 5m x 5m square which can be quickly taken up shortly before a game and rebuilt afterwards.</p> |
