To save money on this trail project, the City of Henderson decided to re-use all of the unattractive excavated rock (rather than hauling it away and replacing it with more expensive decorative boulders). Then, to maintain the project’s aesthetics, they had us apply our patented formula, Natina Rock Color. Seven days later, after Natina sped up the natural oxidation process, beautiful brown colors had developed. Today, this trail looks amazing and the City and its residents couldn’t be more pleased with the results!
