On July 26, 2010 the conservation of the Hagestein Bridge over the river "Lek" near Hagestein, Utrecht has started. The project consists of two phases and will take place between 2010 and 2012.
The current surface protection coating system under the bridge is at the end of its lifetime and will be replaced. The work will start at the east side of the bridge. This part will be done between July 2010 and April 2011. The west side will be done between April 2011 and April 2012.
The old coating layer under the bridge will be removed and replaced by a new coating system. Adittionally a new coating system will be applied to the steel contruction of the river span. After completion of the project the Hagestein Brdige should be free of maintenance again for 15 years.
The work will be performed by the Dutch blasting and painting contractor GSB (Gelders Staalstraal- en schildersbedrijf).
The surface preparation will be done by means of grit blasting (sandblasting) and the abrasive used is Eurogrit aluminium silicate abrasive (coal slag).
