Caltrans needed a 4300 square foot precast, concrete retaining wall to blend into the landscape and forestry behind it. Natina Concrete Solution changed the Crestview Drive wall from a gray color to a rich, earthly brown. Our product is more than a stain, pigment or integral concrete since Natina naturally reacts with the mineral found in the concrete. Our team of professionals helped Caltrans to ensure the right color was achieved. Change the way you see construction with a range of natural browns. All our solutions are natural, environmentally safe and non-toxic.
