Wharf Conservation
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.
Recommendation
- Remove rot, fill timber cracks with cold Goldseal
- Coat replacement bolts with Goldseal, fit and fill the countersink
- When replacing decking apply Goldseal to seal the top of the support member and relay deck
- Spot coat corrosion cells with Brush Grade or completely coat with Industrial Spray Grade
- Goldseal will capillary behind nuts and flanges and will not crack or peel with movement
- Prepare and coat by section the same day
