Tasman Bridge

  The bridge pylons required a long term protection system within the tidal splash zone.

  The pylons surfaces were prepared using hydro demolition to ensure an appropriate surface to rebuild. An impressed current anode protection system was installed to the full exposed face. The surface was then rebuilt back to desired profile with reinforcing mesh and application of mortar to thickness. The lower splash zone was box and poured. The upper levels with gunnite mortar spray.
