Concrete Bridge Deck Sealing: Keeping Your Bridges Strong

They penetrate the concrete and micro and hairline cracks to provide a protective barrier on the bridge deck surface. Studies show that concrete sealers significantly slow the ingress of chloride ions into the concrete decks. A protected deck will last longer than an unprotected deck. Decks should be treated every 3-4 years for the best results.
