GEORUNNER® 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 for outlet protection, drainage ditches and swales instead of costly, higher maintenance rip rap. Shorelines with moderate wave action are also protected from erosion with GEORUNNER Mats. 

Colorado State University (CSU) hydraulics testing: GEORUNNER increases baseline TRM shear stress and velocity performance by a factor of 6.1 and 2.6, respectively.

Key Benefits

• 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 & End-to-End Connection: Overlapping tabs for an integral connection.
• Natural Appearance: 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.
• Performance Backed by Research: Testing at Colorado State University verified the GEORUNNER mats can withstand up to 30 fps when vegetated. 2 to 3X improvement over TRM’s.
