Problem

Railroad Overpass had concrete deck failure; surface failure, rebar corrosion and exposure, and concrete spalling. Failure was consistent with chloride contamination and chemical breakdown of the concrete, exacerbated by age, exposure to the elements, and freeze thaw cycles.

Solution

SURTREAT® products were spec’d and used to rehab the failing concrete structural members and to give the structure extended life.

SURTREAT® is a proprietary, water based, environmentally friendly solution of activators and migratory aids that inhibits rebar corrosion, increases strength and reduces porosity in reinforced concrete.

SURTREAT® Solutions

  • Inhibits salt, water, air and contaminates from penetrating the concrete and forms a better seal in the pores and micro cracks
  • Controls pH and maintains the high alkalinity in the  concrete and is highly acid resistant
  • Migrates to the rebar in liquid and ionic phase and reacts to form a very stable passivating film – more stable than in new concrete
  • Converts rust to a stable, inert compound – and increases compressive, flexural, and tensile strength. Also increases hardness and abrasion resistance

Scope of Work

  • All loose, delaminated concrete was removed with hand tools. Concrete taken to solid surface. 
  • SURTREAT® spray applied to exposed surfaces and rebar.
  • Deck patched. Repairs made with concrete mix matching original.
  • SURTREAT® was spray applied to the entire bridge deck.
  • Asphalt overlay applied to deck.
