The City of Scottsdale, AZ needed a permanent protection solution for an eroding roadway drainage channel fronting commercial developments along Bell Road. Riprap and concrete were unpopular ideas and exceeded the city's budget for erosion control on this project.


Propex worked with Gannett Fleming to propose PYRAMAT® 75 to reinforce native vegetation to provide a UV-stabilized, permanent lining capable of withstanding heavy flows from desert monsoons.

As a high strength woven material with up to 75-year UV resistance, PYRAMAT® 75 was an aesthetic hard armor alternative with native plantings.
