Fosroc repairs Eastern Road water bridge

 In Issue 8

Fosroc products were chosen for repairs to the abutments of the Eastern Road water bridge, which forms part of a new coastal defence scheme along the north of Portsea Island and is a major route into Portsmouth. The abutments, which had suffered erosion due to the coastal environment, required re-facing to ensure the bridge remained structurally sound.

A dry spray repair mortar was required for this project due to the large area of embankment that needed to be repaired and protected. Fosroc’s Renderoc DSR was chosen for the tidal areas due to its fast curing properties, early strength gain and low rebound. In other areas where fast curing was not so crucial, Renderoc DS was used.

Both materials are applied by dry spray methods and are specially designed for large repair areas and for enlarging or strengthening existing retaining walls or tunnel structures. They also meet the requirements of the Highways Agency Specification and EN1504.

Members of Fosroc’s technical, operations, supply chain and customer services teams worked closely together to ensure that the contractor had material readily available and delivered exactly when required. The rapid setting time of Renderoc DSR and the fact that there is very little rebound resulted in improved productivity, reduced wastage and no contamination of the coastal water.

Gunform International Contracts Manager commented: “The material performed excellently and produced a first class job. We would certainly have no hesitation in using the products again and in recommending them to Clients in the future”.
