E5® is approved and specified by the Colorado Department of Transportation. Engineered for Colorado's high-altitude conditions, extreme freeze-thaw cycles, and mountain infrastructure demands.
Colorado's high-altitude environment creates some of the most demanding conditions for concrete — extreme temperature swings, intense UV exposure, and aggressive freeze-thaw cycles. E5® Internal Cure is CDOT-approved and delivers the permeability resistance and durability needed for Colorado's mountain highways, bridges, and infrastructure.
