| Comments | Requires "leave-out" section at guard rail and end treatment posts. | Preferred application is on new rail with placement following post installation and before rail is placed. | Repair and replacement can be conducted by Maintenance crews with existing equipment. Preferred placement is with "Krafco-type" machine for joint sealing. | Do not use in areas or Districts where pesticide application is prohibited. Fabric must have a cover material to prevent movement and improve asethetics. Do not place near water courses. | Probably the most cost effective product, considering the full life-cycle cost. Preferred application is existing guardrail with long life plans, new guardrail if minor concrete not optimal. 6% to 8% recycled content . Requires installation above 50 F. Can tie into stormwater system. |
