SISTEMA ARMORMAX® 75 for Erosion Control and Slope Stability

The most advanced and resilient technology for preventing severe erosion and stabilizing surficial slopes is PROPEX® Armormax®

PROPEX Armormax is composed of High Performance Turf Reinforcement Mat (HPTRM) and Engineered Earth Anchors that work together to lock soil in place and protect against hydraulic stresses.

Solmax’s HPTRM technology features patented ultraviolent stabilization and high tensile strength to provide up to 75 years of slope protection and erosion mitigation, even in environments with direct exposure to sunlight. Additionally, the HPTRM is designed to accelerate vegetative growth, exhibit high resiliency, and feature strength and elongation properties to limit stretching in saturated conditions.

Corrosion resistant Engineered Earth AnchorsTM (EEA) secure the HPTRM to the ground. EEAs are designed to provide resistance to shear and lateral forces, and embed beyond the predicted plane of failure. The PROPEX Armormax system uses either a B1, B2, or B3 anchor depending on the application and environment. Tested. Proven. Trusted.

The U.S. Army Corp of Engineers (USACE) commissioned Colorado State University to test erosion resiliency of HPTRMs for 500-year hurricane overtopping conditions. Testing showed that Armormax provided increased levee resilience and reduced the risk of breaching caused by overtopping. The USACE has now installed more than 1 million square yards of PROPEX Armormax on coastal and river levees.

Design and Performance

• Provides permanent erosion protection for up to 75 years
• Withstands extreme hydraulic stresses
• Provides temporary shoring and stabilization for constructed slopes
• Resistant to non-hydraulic stresses from debris and mowing and maintenance equipment
• Resistant to fire using non-halogen fire retardant technology
• Highly UV stabilized for applications with little or no vegetation
• Outlasts other slope reinforcement methods yielding significant cost savings
• Ease of installation reduces time and labor costs
• Lightweight and easily transported into areas with access challenges
• Reduces the amount of space needed for a right-of-way

Environmental

• Recognized by the EPA as Best Management Practice (BMP) for improving water quality
• Verified carbon footprint is up to 30 times smaller than traditional hard armor
• Recognized by FEMA as a nature-based solution
• Filters sediment and pollutants to improve water quality
• Encourages infiltration of water back into the ground water table
• Proven to reduce erosion and reinforce vegetation for low-impact, sustainable design
• Yields a vegetated solution that is more aesthetically pleasing than traditional hard armoring solutions
• Maintains cooler water temperature than traditional hard armoring, which is healthier for aquatic habitats

• Arid and semi-arid environments where vegetation densities of <30% are anticipated
• Earthen Dams and Spillways
• Roadway Embankments
• Canals/Stream Banks
• Steepened Slopes
• Channels
• Levees
• Areas prone to wild fires
• Defensible spaces
