| Comments | Use only in combination with geotextile barrier or herbicidal fabric under mulch. See detail. Slope installation may require cellular confinement material for stability. | Requires establishment period to control weeds until full coverage is attained. | Proper base design and preparation is necessary to prevent cracking and subsequent weed growth. Matching color and pattern for repairs is difficult. | In gores or other traffic areas cobble "roughness" must be limited, see detail. Installation adjacent to guard rail posts requires "leave-out" section. | Repair and replacement is typically minimal and can be conducted by Maintenance crews with existing equipment. Vegetation may occur in spots. |
