THE CHALLENGE OF BRIDGE MAINTENANCE

Massive constructions under pressure

Synopsis

Even the most basic bridges are engineering challenges exposed to the elements (wind, rain, seawater...) that damage these massive constructions. Intensive road traffic is also an additional constraint. A crack, even a microscopic one, or a rust spot in the wrong place can have serious consequences.

To avoid the worst, bridges are subject to permanent controls and repairs using advanced techniques such as breaking concrete with high-pressure water or cutting a cable so tight that it could snap like a giant whip.

Maintenance specialists perform daily tasks that are not well known to the public to prevent tragedies.
