b) Today's Offering (May 3, 2024): 






Authors' Note: Surveillance of tension cables in pre-stressed concrete is an arduous process, but is essential in older buildings, particularly in parking garages, although apartment towers may also be at risk. Sampling by drilling into the slabs only allows assessment of whether cables have failed, i.e. are broken, and are no longer under tension. Since the 1980s, the development of occlusive plastic fittings at attachment points has apparently reduced the possibility of corrosion due to moisture, a major cause of failure.

The author concedes a lack of professional knowledge concerning this problem. Please consult a structural engineer.
