Concrete Repair and Protection


Ellerton Over Bridge, SH1

The same methodology of repair was followed to the Kekerengu River Bridge and the Kekerengu Rail Bridge with all repairs by box and pour method using Emcekrete SCC. Although the Ellerton Over Bridge was the smallest of the three bridges, it required some of the largest suspended repairs over the active rail line. Speed restrictions were set for the passing trains with core samples being taken once the repairs had cured, to check the bond of the Emcekrete SCC to the existing substrate had not been affected. All bridges were then coated with Emerstop Cream to decrease water penetration into the concrete. A total of 0.8m3 of Emcekrete SCC was used on the Ellerton over bridge.
