Since 2007 Kynningsrud Prefab does not use the highly valuable natural resource, natural gravel, in our production but instead crushed stones.
At the forefront regarding environment and energy saving
Kynningsrud Prefab is at the forefront when it comes to environmental aspects, compared to equal companies. Kynningsrud Prefab has for a long time used crushed ballast instead of natural gravel so as not to deplete the ecosystem’s natural water purification. The manufacturing process includes complete recycling of sludge water, waste concrete and residual concrete.
Another strong environmental advantage of our concrete products is that concrete structures store heat. Storage capacity significantly contributes to cutting the very expensive peaks in energy consumption during cold winter days.
