Use & Purposes
Pyramat® 25 TRMs are perfect geosynthetics for moderate-flow storm water channels, banks and steep slopes where both immediate and long-term erosion control is needed. Using our patented X3® fiber technology, a Pyramat turf reinforcement mat traps more seed, soil and water in place than traditional hard armor products, yielding faster and fuller vegetation. X3 also provides reinforced vegetation with twice the erosion protection of other TRMs and erosion control blankets.
Pyramat® 25 TRMs are available in 1st or 2nd generation material construction. Our 1st generation TRMs are constructed of a dense web of polypropylene fibers positioned between two biaxially oriented nets. 2nd generation TRMs feature a 3-dimensional woven material construction which allows increased design life over 1st generation netted, fused, glued or stitch-bonded TRMs. All of our TRMs are made of 100% synthetic, ultraviolet (UV)-stabilized components and are completely non-degradable.
Second generation TRM. A unique, patented matrix of pyramids formed with X3 fibers that gridlocks soil in place under high-flow conditions. 3-D woven material with superior tensile strength for loading and/or survivability requirements.
Greater flexibility to maintain intimate contact with subgrade, resulting in rapid seedling emergence and minimal soil loss. Completely interconnected yarns that provide superior UV resistance through the TRM. Available in green or tan.
EC DESIGN meets Hydraulic Engineering Circular No. 15 (HEC-No15) and Revised Universal Soil Loss Equation (RUSLE)
• A comprehensive erosion control modeling application tailored to help you provide engineered solutions to erosion control problems
• Provides in-depth modeling using HEC-15 analysis for channel protection, and RUSLE analysis for slope protection, while incorporating tested and proven erosion control solutions
• Expands the traditional erosion control modeling, design, and selection process by integrating non-hydraulic stresses, functional longevity, and performance in critical scenarios for consideration
• Easy-to-use data entry, analysis tools, and report generation
• Tabulated results with product recommendations and customized, personal technical support from the Propex Engineering Services team

Pyramat® – Blue Metal Hill
During construction of the Hume Highway the consortium tasked for the design and construction of this project encountered a number of environmentally sensitive areas through which clean water open drains had to be constructed. The original design called for traditional concrete drains and rock beaching.View More Case Studies
