Weber - Saint-Gobain

Tower Bridge

One of London's best known landmarks has been proudly controlling the Port of London since its completion in 1884. When it was constructed, the bulk of the traffic crossing the River Thames was horse drawn which posed little threat to this most imposing of structures. Over the intervening years, however, the bridge has been subjected not only to ever larger volumes of traffic but more importantly, vehicles with a much higher loading capacity. Thermal movement and possibly the vibration caused by the traffic have combined to pose a threat to some individual parts of the bridge. Substantial cracking of the cast iron lamp stand supports was posing a threat to their structural integrity. Modern technology has come to the rescue of these irreplaceable lamps, unique to the Tower Bridge.

As a Grade II listed structure, the external appearance of the lamp stands could not be altered which determined that any remedial action would need to be invisible. Upper sections of the lamp stands were dismantled and all contamination was removed from the inside sections of the main supports in preparation for further actions. New plates were welded where appropriate and static cracks were filled using webertec EP structural adhesive. Finally all internal surfaces were strengthened using webertec force carbon sheet which has a modulus of 240 kN/mm<2. webertec force carbon plate has provided the strength that ensures the lamp stands will withstand the forces which the modern world will subject them to in the future.
