TUNNELS

The goal of this study was to evaluate the contamination present within the walls of this motorway underpass.

 

The rebar spacing, concrete cover, contamination and corrosion risk were mapped.

It was concluded that there was no major contamination within the structure. Some hotspots were located, they were attributed to water running through cracks.
