Guardian-BD

• Spray-applied, multi-layer elastomeric system designed for vehicular bridge decks.
• The fastest-curing layers can be placed without compromising adhesion to the substrate or the long-term life of the waterproofing.
• The Thurmont, Maryland renovation was coated one lane at a time, and each phase was finished in two days.
• Aggregate is broadcast into the final membrane layer so the asphalt overlay bonds mechanically.
