Waterproofing membrane layer under asphalt.
Dencryl Bridge Road is a polyurethane & methylmethacrylate hybrid spray applied waterproofing membrane for use at concrete- and steel bridges. Dencryl Bridge Road Waterproofing system provide 100% effective seamless waterproofing thereby denying entry of water, chloride and de-icing salts from permeating into and percolating through the structural concrete deck and thus preventing the steel reinforcement corroding. This also includes corrosion inhibition of orthotropic steel decks etc. where these are the decks of choice.
Dencryl Bridge systems are only installed by authorised and approved applicators.
Bridges are continuously exposed to severe stresses and typical factors affecting their longevity, include inadequate protection specified at design phase, quality and handling of concrete and/or steel, physical and chemical exposure, climatic conditions, traffic types and frequency and regularity and quality of maintenance.
