The Federal Highway Administration specified Natina Rock Solution to treat 7,500+ square feet of mechanically stabilized earth (MSE) walls in Utah. The rock wall was originally filled with light, gray rock that contrasted harshly with the surrounding landscapes. Natina's patented formula naturally reacts and oxidizes with the rock surface to create a beautiful earth-tone, brown finish. The reactive color is long-lasting and requires little to no maintenance. All our solutions are natural, environmentally safe and non-toxic.
