Wharf Conservation
Page: 1234

Port Facilities, wharfs and assets within 1Km of the coast.
Older wharfs are a combination of timber/concrete and steel. Fixings can be countersunk into timber or concrete. Some flange, bolt and rod reinforcing or triangulation braces are difficult to prepare or consist of bolted intersections which can be prepared and paint coated but will move. This movement cracks most coatings allowing salt water and chloride ions to create localised corrosion cells. These undermine the coating and blow it out from underneath.
