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.
