Drainage – Tray Denver, CO
BRINGING GREATER ABRASIVE RESISTANCE TO PARKING LOT DRAINAGE RUNOFFS
Because of the heavy runoff and seasonal flooding Denver is famous for, drainage trays carry a lot more than water. They also ferry rocks, pebbles, deicing chemicals, and other abrasive materials that slowly abrade away the surface of concrete channels. These small impact craters become cracks and holes, allowing water to seep into the structure.
That’s what Metro Mix told the Contractor (CASI Concrete) of Castle Rock about EdenCreteTM. The company was contracted to pour several new concrete drainage systems throughout Castle Rock and the greater Denver area, so they were open to exploring new ways to improve the longevity of their concrete.
59% Increase in Abrasion Resistance
ASTM C779, Proc. C
The Results
In this field trial, EdenCrete™ increased abrasion resistance of the new concrete by 60% over the original mix design. Furthermore, EdenCrete™ increased the tensile strength of the new concrete by 25%. CASI Concrete also reported no negative impact on the fresh concrete properties.
“The contractor had no idea that EdenCreteTM was in the concrete mix design because it did not influence the fresh properties or the finishability of the concrete. Test results showing enhanced abrasion and tensile strength certainly indicate that EdenCreteTM should have no problem extending the life of the concrete’s (application) in-service conditions typical in a drainage basin.”

Vice President of CASI Concrete
After 18-months in service the trays containing EdenCrete™ are in great shape with no cracks or chemical pitting.
The reference trays are cracked and severely damaged.
Areas of significant improvement for this application
EdenCrete™ enhances concrete in all seven areas, but was specifically selected for abrasion, permeability and tensile strength for this project.
The EdenCrete™ surface is still intact with no visible degradation after 18-months in service. Reference tray showing significant wear
