Sealing of concrete bridge deck, such as with methacrylate. It is to help seal out moisture from penetrating the bridge deck. Work consists of cleaning the concrete surface often with abrasion blasting (shotblast) and compressed air. Material is applied liberally and spread with brooms and/or squeegees to flood the entire surface and seal all visible cracks. Skid/slip resistance is achieved by broadcasting sand into the material before it cures.
