Curlex RoadRunner is a mechanically installed erosion control blanket (ECB) system that has virtually rendered manual installation obsolete.

Curlex-III-Roadrunners-load-at-mill-111315_webIf you work with large projects and would like to drastically reduce your unloading and installation labor rate, RoadRunner ECBs along with our patented installation equipment is your most efficient solution. RoadRunner installation equipment is compatible with skid steer equipment. RoadRunner mechanically unloads, installs the blankets, reduces your crew size, and minimizes labor installation time. In turn, it allows you to complete large projects ahead of schedule, vs. the extra time and labor normally associated with manually installed blankets.

Material Characteristics

roadrunner_3RoadRunner is a patented system designed to allow one person to mechanically unload a flatbed of blankets on-site in less than one hour. After unloading, just change to the installation mode and install with the most labor efficient system available. All you need to install RoadRunner ECBs is one operator and two to three persons to staple the blankets. RoadRunner installation equipment allows you to minimize crew size and maximize labor efficiency by installing wider and longer ECBs. RoadRunners allow for a fast, smooth installation. Available colors are natural Aspen or QuickGRASS® (green pigment) for urban aesthetics.  Curlex is considered the industry standard by many because of the plethora of Curlex Features and Benefits. 

Performance Capabilities

RoadRunner installation equipment will install Curlex ECBs in channels that are accessible by most skid steers.

Steepness: RoadRunner ECBs have been installed on 2H:1V slopes; however, the limitations of equipment and operator skill will vary. Refer to equipment safety manual before installing on steep slopes.
