Presto GeoRunner - Flow/Scour Protection Mats
High-Performance Transition Mats Stop Scour. Protect areas subjected to concentrated flows from scour and surface erosion with Georunner Mats. Fully interconnected mats protect underlying TRMs or erosion control blankets, allowing low-maintenance vegetation at pipe outfalls, drainage ditches and swales instead of costly, higher maintenance rip rap. Shorelines with moderate wave action are also protected from erosion with Georunner Mats. Swales & drainage ditches, pipe & culvert outfalls, spillways, stormwater channels, shorelines.
Better Vegetation Growth
Compared to ScourStop or similar transition mats, the open lattice design of GEORUNNER mats allows for dense, stabilizing vegetation with better root engagement and reinforcement.
Side-to-Side Connection
GEORUNNER mats are connected side-to-side with overlapping tabs and spring steel clips for an integral connection. Other mats do not have tabs and recommend laying their units side to side and joining with plastic straps, which can slide and separate.
End-to-End Connection
GEORUNNER mats are connected end-to-end with rivets with overlapping tabs, creating a flush connection. Other mats recommend ‘shingling’ which can lead to increased turbulence.
Industry Standard Anchors
Duckbill anchors (300 lb pullout), Gripple and stainless steel cable are GEORUNNER anchor components. Other mats use plastic straps, susceptible to breaking, long term strain and cutting.
Natural Appearance.
GEORUNNER mats placed over a TRM offer similar resistance as rip rap, but with a naturally vegetated appearance that supports unimpeded access by mowing / lawn maintenance equipment. Rip rap is prone to collection of garbage and debris and is difficult to maintain.
Performance Backed by Research
Testing at Colorado State University verified the GeoRunner (unvegetated) can withstand up to 30 fps when vegetated. 2 to 3X improvement over TRM’s.
Benefits of GEORUNNER for Scour Protection
- More Economical: Half the cost of rip rap and lower cost than other transition mats in the market.
- Better Vegetation Growth: Open lattice design allows for dense, stabilizing vegetation with better root engagement and reinforcement.
- Side-to-Side Connection: Overlapping tabs and spring steel clips for an integral connection.
- End-to-End Connection: With rivets with overlapping tabs, creating a flush connection.
