Using Integral color, the curbing is created by a variety of stamping techniques. First, pigment is added to the concrete while it is being mixed. Adding the color this way gives you a muted, soft color throughout the curbing. Once the curbing is extruded, the crew goes to work shaping, cutting, and matting the surface to create the desired look. The prices range from $15 to $21 per foot depending on the style. We also install a steel cable inside the curbing for added stability.
