Pyramat 50: A Complete Guide to Long-Term Erosion Control

Pyramat 50, manufactured by Propex (now part of Solmax), is a high-performance Turf Reinforcement Mat (TRM) designed for demanding erosion control applications. Its dense, three-dimensional matrix reinforces vegetation, offering permanent protection in high-flow channels, steep slopes, and other challenging environments. This guide covers what Pyramat 50 is, its benefits, and how it performs in real-world applications.

What is Pyramat 50?

Pyramat 50 is an engineered TRM made from UV-stabilized, high-tenacity polypropylene fibers. It has a unique pyramid-shaped matrix that locks in soil and promotes rapid vegetation growth. Designed for permanent installations, it offers up to 75 years of functional longevity when buried and vegetated.

Key Benefits

  • Superior Erosion Control: Withstands high shear stresses and flow velocities.
  • Vegetation Reinforcement: Encourages root entanglement for long-term stability.
  • UV Stability: Resistant to degradation from sunlight exposure.
  • Environmentally Friendly: Supports natural vegetation growth without chemical treatments.

Common Applications

  • High-flow drainage channels
  • Steep slope stabilization
  • Shoreline protection
  • Stormwater outfall areas

Case Study: Highway Embankment Stabilization

In a recent highway improvement project, a steep embankment was experiencing severe erosion due to stormwater runoff. Engineers specified Pyramat 50 for its proven performance under high-flow conditions. The mat was installed and seeded with native grasses, achieving 90% vegetation coverage within 8 weeks. Even after multiple heavy rain events, the slope showed no signs of erosion, and vegetation remained dense and healthy.

Installation Tips

  1. Prepare the site by grading and removing debris.
  2. Anchor the mat securely at the top of the slope or channel.
  3. Overlap adjacent mats by at least 6 inches.
  4. Seed the area before or after installation, depending on site conditions.
  5. Use soil staples or pins at recommended spacing to prevent movement.

Conclusion

Pyramat 50 is a trusted, long-term erosion control solution for challenging environments. With its durability, vegetation support, and proven performance, it remains a go-to choice for engineers, contractors, and environmental specialists.
