Bridge Rehabilitation

ADVANTAGES OF
SHOTCRETE BRIDGE REHABILITATION

  • Provides structural integrity
  • Improves flow by reducing the roughness coefficient
  • Resistance to the adverse effects of sewage
  • Repair without interference with existing utilities
  • Maintains flow in line while rehabilitation is accomplished
  • Minimum disruption of traffic

Weathering due to freezing and thawing plus the effects of de-icing agents lead to the deterioration of concrete bridges, causing structural damage or complete failure. SHOTCRETE rehabilitation restores these structures to their original condition both structurally and in appearance.

After the deterioration has been removed to sound concrete, the resulting surface is prepared by water/air blasting and the area is restored with reinforced SHOTCRETE. Existing reinforcing steel is cleaned by sandblasting or other means prior to the SHOTCRETE repair. Steel that has lost its effective cross sectional area is replaced with new reinforcing and then lapped or spliced with existing sound bars.

In addition to the existing or replaced reinforcing bars, other reinforcing is often provided with the use of welded wire mesh, polypropylene fibers or steel fibers.
