Flexterra® HP-FGM™ – High Performance Hydraulic Mulch for Erosion Control and Vegetation Establishment

Ultimate Biodegradable Mulch Solution for Challenging Sites
Flexterra® HP-FGM™ (High Performance Flexible Growth Medium) is the most advanced hydraulic mulch engineered for sustainable erosion control and rapid vegetation establishment. Designed for extreme slopes, high rainfall areas, and difficult soils, it outperforms conventional straw, wood, or fiber mulches in both erosion prevention and plant growth.

Why Flexterra® HP-FGM™ Is the Preferred Mulch

Superior Erosion Control

  • Flexterra® HP-FGM™ immediately bonds to the soil upon application, forming a flexible, protective mulch layer that prevents soil displacement and minimizes sediment runoff.

  • Achieves up to 99% erosion control effectiveness, far exceeding traditional straw or wood mulches.

  • Proven performance even on slopes up to 0.25H:1V and in high-velocity runoff conditions.

Advanced Growth Medium for Faster Vegetation

  • Forms a breathable, porous blanket that allows water, oxygen, and nutrients to reach seeds while shielding them from erosion.

  • Creates a micro-environment that enhances germination, root development, and long-term vegetative cover.

  • Delivers ≥ 800% vegetation establishment as tested under ASTM D7322 standards.

High Performance Under Harsh Conditions

  • Works effectively on rocky, compacted, or low-nutrient soils.

  • Resists wind, heavy rainfall, and surface water runoff.

  • Ideal for roadside embankments, dams, quarries, mining sites, and other challenging terrains.

Key Performance Advantages

  • Immediate soil protection after application.

  • Eliminates the need for fine grading or extensive site preparation.

  • Faster germination and more uniform vegetation growth.

  • 100% safe for wildlife; no nets or plastic threads like traditional rolled blankets.

Typical Applications

Flexterra® HP-FGM™ is the preferred mulch solution for:

  • Highway and railway embankments

  • Dams, reservoirs, and water retention areas

  • Industrial, mining, and energy project sites

  • Quarries and reclamation areas

  • Steep slopes, cut & fill areas, and other difficult terrains

  • Landscaping, environmental restoration, and urban green projects

Application and Installation

Easy to Apply

  • Mixes uniformly and sprays smoothly without clogging hydroseeding equipment.

  • Forms a consistent protective mulch layer immediately upon drying.

Optimized for Vegetation Establishment

  • Micro-Pore particles retain moisture and nutrients, reducing evaporation and promoting stronger root development.

  • Crimped interlocking fibers enhance mechanical bonding to the soil.

  • Provides reliable protection during periods of dormancy and ensures seeds remain in optimal conditions for growth.

Environmentally Responsible

  • Made from biodegradable and renewable materials.

  • No heavy metals, chemicals, or fertilizers added.

  • Naturally decomposes into the soil, enriching organic matter and improving long-term fertility.
