The Medway Viaducts are three bridges or viaducts that cross the River Medway between Cuxton and Borstal in north Kent, England. The two road bridges carry the M2 motorway carriageways. The other viaduct carries the High Speed 1 railway line. All three bridges pass over the Medway Valley Line (to Paddock Wood).

Medway Bridge is located over an SSSI site. Chemcrete PAVIX CCC100 was chosen because is was the least potentially harmful concrete protector.

Chemcrete PAVIX CCC100 is a unique water-based product for permanent protection of concrete structures and other porous substrates against temperature and moisture associated problems, such as damage caused by freeze-thaw cycles and chloride ion penetration.

It keeps treated concrete reasonably dry, thus eliminates all water and moisture related deterioration. Chemcrete PAVIX CCC100 is designed especially to protect highway bridges, car parks, buildings and costal structures.
