A rigorous program of preventive maintenance can extend the service life of a road, bridge, underpass or civil structure. This ensures that the maximum value is realised from the initial capital investment. Additionally, regular maintenance proves more cost effective than occasional major repair. The concept of preventive bridge maintenance is built on the understanding that a program of multiple relatively small repairs and activities will keep the structure in good condition. Thereby the large expense of major rehabilitation or replacement is avoided.— — WASHING OF BRIDGES, UNDERPASSES AND TUNNELS — CLEANING AND INSPECTION OF BRIDGE Using our state-of-the-art tunnel washing truck – the only one of its kind EXPANSION JOINT in the region – we undertake the essential washing of bridges, underpasses Significant for safety, as well as avoiding general wear and tear, our engi- and tunnels.
