| Comments | Probably the most cost effective product, considering the full life-cycle cost. Requires "leave-out" section at guard rail and end treatment posts. | Less effective for controlling weeds than portland cement concrete. | If possible native plant material should be propagated from locally collected seed. Proper site preparation, duff preservation and long term establishment are important for success. | Proper base design and preparation is necessary to prevent cracking and subsequent weed growth. Matching color and pattern for repairs is difficult. | Preferred placement behind curbs or with other edge restraints. Base design is important for correct load bearing capacity. Include soil sterilization under treatment. |
