The patented Fürstenberg-PermadurZ®-Bandage consists of a non-rotting and aging-resistant Polythene foil that is used at the outside, and a metal foil that is applied inside to stabilize the system. This allows efficient and cost-effective maintenance of poles in the field.
The foils are applied in winding technology, mainly in the ground/air zone of the wooden pole, but also in other areas that are threatened by decay.
