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
Managing subsurface moisture at Missouri River bridge with MIRAFI
MIRAFI® H2Ri was incorporated into Missouri River bridge approaches to manage subsurface moisture, replace a drainable aggregate layer, and reduce aggregate requirements while supporting pavement construction.
Omega Mine extends AMD treatment capacity with dewatering
At Omega Mine in West Virginia, GEOTUBE® GT500 units help the West Virginia Department of Environmental Protection treat and dewater acid mine drainage from abandoned mines while supporting long-term capacity and compliance.
Dredging and reuse of contaminated sediments
Embraport used dewatered contaminated sediments as structural fill within its terminal platform, saving 400,000 m3 of imported material and reducing earthfill platform costs by 20% to 30%.
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.
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.
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.
