Prevent Scour and Erosion without the Unsightly use of Rocks/Rip Rap!
ScourStop transition mat is a biotechnical replacement for hard armor. It is a mechanically-anchored 4 ft. X 4 ft. X .5 inch semi-rigid, polymer mat designed with voids throughout the structure which enable vegetative growth. Transition mats provide mechanical protection over highly erosive areas; like stormwater pipe outfalls, curb outfalls, over-flow structures, and shorelines. Transition mats provide protection against much higher shear stress and velocities than vegetation alone or rock rip rap; and are comparable in performance to Articulated Concrete Blocks.
- Use ScourStop to protect soil and filter runoff
- Enables Vegetation
- Unlike Rip Rap, ScourStop does not collect debris or cause extra maintenance costs associated with trimming and cleanup

Additional Benefits of Scourstop
• ScourStop is a bio-technical replacement for rock rip rap.
• Vegetation creates greater site amenity and filters pollutants.
• Immediate soil protection at installation – there is no lag time for performance.
• 50-100% higher performance specifications than rock rip rap; especially on slopes.
• 10 times lighter per sq. ft. than hard armor alternatives; but 7 times more ‘hold down’ capacity; transition mats minimize weight-transference problems which de-stabilize sub-soils.
• No maintenance required, especially important for municipalities as end owners of storm water conveyances.
• Increases infiltration and groundwater recharge by promoting vegetation in storm water conveyances.
• Longer functional life than rock rip rap – rip rap erodes away and disintegrates; is not available everywhere.
• Increases safety for children in residential settings by eliminating debris, vermin, and
weeds in rock rip rap.
• Can be re-installed at minimal cost should there be an installation problem or site change.
• Accessibility to any site.
• Reduces Right-of-Way (ROW) area. Less space for Right-of-Way, means more `rentable’ space and/or parking for the land owner.
• Ease and speed of installation. Extensive installation savings.
• Local approval for 404 Permits. Minimizing the excavation and fill requirements for a project will likely enable local permit approval - requiring less than 8 weeks; and avoiding multi-year permit approval if your permit goes to the federal level.
