What is the life expectancy of the PermaBase board?
The chemical and physical composition gives it a very low water absorption, which explains its great dimensional stability. Therefore, it cannot be damaged by great differences of temperature. On top of that, PermaBase is rotproof. The armature used has a special treatment against alkalis contained in the cement. PermaBase does not stop solidifying itself as the years go by (like any concrete does). These facts demonstrate the long life of PermaBase, as seen in the field and in the laboratory during accelerated aging tests. But the most evident proof is the fact that PermaBase has been proven in Canada, a country with the most drastic changes in weather in the world.
