Concrete renovation of pylon foundations for the Goor-Hengelo high-voltage power line
The work involved excavating four concrete foundations around each mast to a depth of approximately 50 cm, sanding and cleaning the concrete, and repairing and levelling it where necessary. A primer coat was then applied, followed by a two-coat coating system. The steel bases on the foundations were sanded and treated with a two- to three-coat component paint. Finally, the ground around the footings was backfilled.
