Lightweight PROPEX® Armormax® was installed by tethered workers on steep slopes, securing the terrain with PROPEX Pyramat® 75 HPTRM and B2 Engineered Earth Anchors™
The PROPEX Armormax® system was live staked with trees and seeded, ensuring long-term erosion control while integrating vegetation into the stabilization solution
Big Bethel Blueway channel stabilization supports stormwater resilience in Hampton
The City of Hampton used PROPEX® Armormax® to stabilize the Big Bethel Blueway drainage channel. The system showed no erosion after floodwater reached four to six feet during installation while supporting a vegetated approach to erosion control.
Stabilizing lost trail pass with PROPEX Armormax
At Loss Trial Pass, PROPEX® Armormax® with B3 anchors stabilized a steep, failing slope beside highway 93. The system addressed remote access, heavy snow loading, and erosion while allowing the roadway to remain open during installation.
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.
TransCanada has the largest pipeline infrastructure in Canada. In 2008, TransCanada, now known as TC Energy, successfully ran a large diameter gas pipeline below the St. Maurice River in Cap de la Madeleine, Quebec. After construction, the steep 1:1 slopes that were cleared for access began to experience erosion and stability issues. Sandy soils caused slides and deposited sediments along the river’s bank.
Due to the terrain’s extreme slopes and the remote area, access to the site was prohibitive of most slope stabilization solutions. PROPEX Armormax® was selected because it is light weight, easily transported to remote areas, and is low impact development (LID). It also provides provides immediate and long-term stabilization. Pipelines workers tethered to the top of the slope and installed the PROPEX Pyramat® 75 High Performance Turf Reinforcement Mat (HPTRM) and B2 Engineered Earth Anchors™ with ease.
After installation, PROPEX Armormax was live staked with trees and seeded. Twelve years later, the trees and vegetation have matured and continue to prevent erosion of sediments into the river with a natural, vegetated solution.
