Epoxies have been in use in the US for over 40 years as concrete bridge deck overlays. To seal cracks of the bridge deck. To prevent water and chloride ions from salt to penetrate the concrete. To protect corrosion in the deck’s reinforcing steel due to moisture intrusion.
Thin Epoxy Overlay Summary • Seals cracks in bridge deck by bridging • Use on any deck 1 year old or greater with a fair or better top and deck bottom condition • Increases skid resistance • Dark Aggregates deter icing of the bridge deck • Heavily dependent on surface preparation • Life expectancy 15-20 years
Epoxy or Polymer Overlays - Norcon Corp
Epoxy or polymer overlays is a proven solution for prolonging the wearing surface of bridge decks as well as providing a high friction surface to other concrete and asphalt surfaces. An epoxy overlay creates a highly durable surface, improving the driving safety, and reducing life cycle maintenance costs for the owner.
Epoxies have been in use in the United States for over 40 years as concrete bridge deck overlays. Over this time there have been many changes to the basic epoxy resins primarily due to problems caused by high modulus materials, UV sensitivity, leaching and environmental issues.

Thin Polymer Overlays (TPO) provide a high-friction, long-lasting wearing course on concrete bridge surfaces that protects the deck from moisture and deicing salt penetration, inhibiting future corrosion.
bridge deck rehabilitation decisions. The objective of this study was to develop guidelines for selecting bridge deck treatments for different deck conditions and deck materials. The guidelines provided in this report consider current deck conditions and deck materials and provide a means to make general repair decisions.

With anti-skid overlay and deicing capabilities that reduce or prevent frost and ice formation on Bridge and Parking Decks, E-bond is also used as a high friction surface treatment and has thixotropic capabilities for ramps and horizontal curves.
TK-EPOXY BRIDGE DECK OVERLAY 2109 is a low viscosity. 100% solids, solvent-free, two-component epoxy system. Formulated to seal, protect and lengthen the life of concrete
Epoxy and Polyurea Concrete Repair Products
Formulated to seal, protect and lengthen the life of concrete bridge decks and parking structures, TK-EPOXY BRIDGE DECK OVERLAY 2109 also provides exceptional skid resistance with a top-layer of specially selected aggregate.
Proper application of a 2-lift thin polymer overlay on decks that are in good repair (no significant chloride contamination, corrosion and/or deck surface defects) have a life expectancy of seven to 15 years. The main advantage of thin polymer overlays is the long-term preservation of friction coefficients as the deck ages.
