Keywords Winn & Coales (Denso), Corrosion prevention, Filling
The completion of the strengthening of the M2 bridge over the Medway by contractors Edmund Nuttall Ltd to carry M2 road traffic means that there is now a bridge carrying East to West traffic and a second for West to East. A third bridge to be built at this location will be for the high speed Chunnel rail link.
Winn & Coales Denso Void Filler has been used to play its part in the anticorrosion protection of the prestressed stay cables that support the bridge, which were installed by specialist sub-contractors Freyssinet (Plate 1). The 96 prestressed cables, with a maximum length of 148m, are pregrouted and Freyssinet specified Denso Void Filler to provide long life protection to the end caps.

Denso Void Filler is a petrolatum compound which contains additives to displace moisture and inhibit corrosion. It can be, injected cold or hot, if required, from a heated tank with its own pumping system specifically designed by Winn & Coales Engineering Division.
Winn & Coales Denso Tape was also used on this Medway bridge for protection on the supporting Macalloy bars at the side of the bridge.
