I-295 Scenic Overlook Concrete Barrier (2005)

CeramycShieldTM (CS) was applied to a cleaned area of the I-295 Scenic Overlook Concrete Barrier at the Delaware Water Gap, in 2005. This project was designed to show the photocatalytic and oxidative self-cleaning effects of the CeramycShieldTM technology. New Jersey is noted for high summer humidity and algae growth on NJDOT concrete assets. This white coating version of CeramycShieldTM was specifically designed to improve the visual appearance of the concrete asset (cleaner look during the day, more visible at nighttime) and preserve the surface from biological growth.

Most types of biological growth emit acids that etch the surface and erode concrete in order to create more habitat. CeramycShieldTM has a very strong photocatalytic effect (absorbs UV energy to create free radical hydroxide ions from humidity) and is surface oxidative (generally biologically impervious) to algae, fungi, bacteria and other microbial life due to the metallic elements in the alumina-zirconia silicate inorganic polymer.

CeramycShieldTM also stabilizes the surface chemistry of concrete, stopping carbonation and environmental exposure-driven erosion, allowing concrete to remain pristine.
