Bridge deck waterproofing is essential to protect these structures from water ingress, aggressive environmental exposure and ongoing mechanical stress. Without effective waterproofing, bridge decks are vulnerable to accelerated reinforcement corrosion, reduced structural integrity and increased maintenance costs, which can significantly shorten service life and create safety risks for users. Sika bridge deck waterproofing products are designed to provide durable protection to bridge decks and their construction and movement joints, using elastic and crack-bridging solutions that accommodate dynamic loading while maintaining long-term waterproofing performance.
