Beginning in 1980, the Kansas Department of Transportation (KsDOT) used alkyl-alkoxy silane to waterproof 57 newly placed concrete decks or overlays on old or new bridges. In 1985, research teams inspected 14 of the treated bridge decks to see if the silane kept salt out of the concrete.
For several years the Kansas Department of Transportation (KsDOT) was faced with shear cracks in the concrete girders of two-girder reinforced concrete bridges. A technique that would repair the cracks and increase the girder's shear capacity was needed. Post reinforcement, a repair method that does both of these things, was developed and is now used by the KsDOT.
