Ship factory deck now in tip-top condition

Citi-Con undertook repairs to a ship factory deck at the Port of Cape Town, Western Cape.

They were completed on behalf of a leading fishing company and producer of high-quality chilled and frozen foods.

Citi-Con designed a cutting-edge repair solution for this infrastructure, considering that it is located in a very aggressive environment. The high salinity content of the seawater has led to extensive corrosion of reinforcing bar inside the concrete deck. This is evident by significant concrete spalling.

We started by opening the spalled areas of concrete to expose the rebar inside and then cleared the substrate of loose material and debris. Thereafter, rust was removed via hydro-blasting and the reinforcing steel pushed back by 15mm wherever possible. The steel reinforcing was then treated with a corrosion-resistant primer before reinstating the areas with a 10mm to 20mm-thick repair mortar.

Stoncor Stonclad UT high-impact, abrasion, thermal-shock cycling and chemical resistant mortar was then be applied to the substrate. This was followed by the application of a build-up system.

To complete the repairs, Flowcrete Deckshield was applied with a sheepskin roller. This system provides excellent UV, chemical and slip resistance, making it ideal for this application.
