Corrosion is a major threat to concrete and steel bridges, roadways, tunnels, overpasses, and parking decks. Exposure to water, air-borne pollutants, and vehicular traffic are all causes of today’s deteriorating transportation infrastructure.

SPI offers various anti-corrosion, and waterproofing polyurea coatings, specifically formulated to protect concrete and steel substrates.  Extremely durable, our coatings will withstand heavy vehicular traffic, weather cycling, and salt and chemical exposure. They keep moisture out by providing excellent impermeable barriers, with or without geo-textile fabrics.

The effects of strong ground motion, as encountered during earthquakes, and daily freeze-thaw cycling can also contribute to the deterioration of transportation infrastructure.  Our high-elongation polyureas remain flexible, allowing them to move with the substrate, while providing structural integrity.

These unique polyureas form a seamless membrane that safeguard against water ingress, corrosion, and salt exposure, helping to eliminate further deterioration, and ultimately extending the service life of the infrastructure.
