Highway overpasses are subject to harsh environmental and traffic conditions that speed their deterioration and cracking. In addition to the age of many of these structures, water and road salt seep down the cracks and collect in the pockets under the negative steel, and freezing of the water can cause the bridge deck surface to become pitted and extensively cracked, requiring expensive repairs.

To incorporate composite grid as repair and waterproofing to leaking joints on highway 33 at the 340 overpass.

Material Used: FORTRESS Carbon/Kevlar Grid 48K with 4020 epoxy resin
