Crackbond Bridge-Gard is a multi-purpose epoxy polymer concrete overlay for high-stress bridge decks, parking structures, and loading docks.
Crackbond Bridge-Gard from Adhesives Technology is a 100% solids epoxy polymer concrete overlay for high-stress decks. It is moisture insensitive, needs no primer, and places from 3/4 in. to 10 in. for overlays, spalls, ruts, and joint nosings on bridges, parking structures, and docks. At 75°F the overlay is typically open to traffic in under 3 hours. The larger kit of the same overlay is the Crackbond Bridge-Gard 1.34 cu ft kit.

How thick can Crackbond Bridge-Gard be paved in one overlay?
Crackbond Bridge-Gard is placed from 3/4 in. to 10 in. cross-section. That range is why it is used as a deck overlay, a nosing mix, and a deep spall repair without switching chemistries.
How soon can traffic return on Crackbond Bridge-Gard at 75F?
Crackbond Bridge-Gard is rapid-cure. The current sheet opens the overlay to traffic in less than 3 hours at 75F. That is the infrastructure reason to keep Bridge-Gard on a night deck closure.
Is Crackbond Bridge-Gard used as bridge nosing at joint headers?
Yes. Crackbond Bridge-Gard is listed as bridge nosing material for joint headers and edges, and for extending deck life on bridges and parking structures. High early bond is the reason it holds at those headers.
Can Crackbond Bridge-Gard correct ruts and grading?
Yes. Crackbond Bridge-Gard levels or corrects concrete grading and ruts, and repairs concrete spalls. High tensile strength with high elongation is how the sheet explains rutting resistance on decks and docks.
What placement temperature window does Crackbond Bridge-Gard list?
Crackbond Bridge-Gard is applied and cured between 65F and 95F. Stay in that band so the epoxy polymer overlay reaches the published traffic window. Hotter or colder decks need a different closure plan, not a different thickness.
Is Crackbond Bridge-Gard meant for loading-dock floors as well as bridges?
Yes. Rehabilitating concrete flooring and loading docks is a listed use, along with parking structures and bridge decks. High-stress wheeled traffic is the common jobsite condition.
