Presto GeoRunner - Surface Flow Protection System

Presto GeoRunner Flow Protection Mats are a low-cost option for protecting embankments from scour and the erosive effects caused by water flow.

• Series of light-weight, durable mats protect surfaces from intermittent and concentrated surface flows, water fluctuations and light wave action.
• Interconnected mats ideal for protecting drainage ditches/ways, culvert outfalls, spillways, stormwater channels and shoreline embankments exposed to concentrated flows or fluctuating water.
• Effective in areas where ECBs and TRMs cannot be used.
• Nearly "invisible" once fully vegetated.

Contractor-Friendly Mats
Contractors prefer GeoRunner transition mats over concrete systems because they are less expensive, flexible, easier to install, and are less obtrusive.

• Open mesh design promotes dense grass growth through the openings, increasing system stability, reducing visibility and providing a more natural blending with the environment.
• Mats secured side-to-side and end-to-end, creating a fully integrated, flush surface.
• Mats securely anchored with industry-standard components to resist pull-out caused from saturated soils.
