Slope stabilization behind Metal Art Museum with PROPEX
Overview
When gabion baskets failed to prevent continuous slope failure on the hill behind the Metal Art Museum, a solution was needed to provide permanent slope stabilization. It was critical that the slope be stabilized against both global and surficial failure.
Challenge
To provide a geotechnically sound alternative, soil nails were used to stabilize the deep-seated failure and the PROPEX® Armormax® and Engineered Earth Armoring Solutions® was chosen to provide surficial stability.
Solution
With its combination of the High Performance Turf Reinforcement Mat (HPTRM) and PROPEX Armormax Engineered Earth Anchors®, this system provided a dynamic erosion control and slope stabilization solution and allowed for shorter and less soil nails to be used than originally designed. The HPTRM component is engineered to lock-in seeds and moisture, promoting rapid root development and allowing the slope to vegetate quickly.
Soil nails were installed to address deep-seated slope failure, while PROPEX® Armormax® provided surficial stability and erosion control.
The PROPEX® Armormax® system, featuring HPTRM and Engineered Earth Anchors®, reduced the need for additional soil nails while stabilizing the slope
The HPTRM locked in seeds and moisture, promoting rapid root development and ensuring long-term vegetation growth on the slope
