Abstract:
A Philadelphia firm used a system of drilling holes into concrete walls and injecting epoxy under 3000 psi (20.7 MPa) pressure into those holes to repair cracking and deteriorating concrete bridge pier walls at the Water Street Bascule Bridge in Milwaukee, Wise. The epoxy was injected from the interior face of the walls against high hydrostatic pressures on the exterior face. The epoxy stopped the infiltration of water through the cracks and cavities in the concrete walls, allowing workmen to remove deteriorated concrete and apply a new interior layer of special mix water-resistant concrete to rehabilitate the wall.
