Turf Reinforcement Mat (HP-TRM) • Permanent Erosion Control • Vegetated Channels & Slopes

EnkaMat R45: The No-Float HP-TRM for Permanent Erosion Control

EnkaMat R45 is a high-performance turf reinforcement mat (HP-TRM) that combines a high-tenacity polyester geogrid with a thermally fused, three-dimensional nylon monofilament matrix. In plain terms: it’s a tough, interlocked mat that anchors vegetation and soil in place—so channels, canals, banks, shorelines, levees, and steep slopes can handle flow and weather without washing out.

What Makes EnkaMat R45 Different?

Integrated Structure: The geogrid and 3D nylon matrix are fused into a single, homogeneous system. In practice, this means the mat acts as one solid reinforcement layer, resisting movement above and below the soil surface.

  • Permanent erosion control for vegetated channels, canals, banks, shorelines, and levees with expected shear stresses ≤ 20 psf (pounds per square foot).
  • Permanent erosion control for moderate to steep slopes (≤ 0.25H:1V) — that’s up to 1 foot of horizontal run for every 4 feet of rise, a very steep grade.
  • Substrate for hydraulically applied FGM™ and bonded fibers: creates a stable skeleton for growth media and seed.
  • Redistributes shear within the soil, limits differential settlement, and improves internal stability of the soil mass.
  • No-Float TRM: the material composition prevents buoyancy, so it stays put during high water.
  • High stiffness / low creep: maintains performance under sustained loads.
  • Excellent soil interaction with all granular soil types.

Where EnkaMat R45 Excels (and Why)

  • Vegetated Channels & Canals: When flows increase, the reinforced root–mat composite resists shear up to 20 psf, protecting soil beneath.
  • Steep Slopes: On grades up to 0.25H:1V, R45 stabilizes the surface so vegetation can take hold, reducing slide and rill formation.
  • Shorelines, Banks & Levees: The No-Float design helps resist lift during high water, while vegetation locks everything in place.

How It Works (Simple Explanation)

The geogrid acts like a reinforcing backbone, while the 3D nylon matrix entangles soil, seed, and fibers. Once vegetation grows through the mat, roots weave into the system—creating a strong, flexible “green armor” that resists water velocity and shear.

Installation Overview (Step-by-Step)

  1. Grade & prepare the subgrade; remove debris and create a smooth, compacted surface.
  2. Anchor trenches (crest & toe): excavate per design (commonly 6–12" deep) to lock the mat edges.
  3. Place R45 downslope or downstream; overlap per manufacturer guidance (commonly 6–12" in flow direction).
  4. Secure with pins/staples in a staggered pattern; increase density at overlaps, curves, and high-stress zones.
  5. Apply seed & growth medium (FGM™ or bonded fiber) over/through the mat as specified.
  6. Close trenches, backfill and compact; inspect before first storm event.

Best-Practice Tips

  • Always align overlaps with the direction of flow; avoid “fish mouths.”
  • Increase anchoring density at inlets, bends, and transitions.
  • Schedule installation to allow germination before peak flow season when possible.

Case Study: Municipal Channel Retrofit with EnkaMat R45

Site: 1,200-ft vegetated drainage channel, mixed granular soils (silty sand), Midwest, USA
Challenge: Seasonal flows produced shear spikes that repeatedly scoured the bed and side slopes, undermining vegetation and clogging downstream culverts.

Solution

  • Installed EnkaMat R45 with crest and toe anchor trenches and a tighter pinning schedule at bends.
  • Hydroseeded with native mix and applied FGM™ to jump-start vegetation through the 3D matrix.
  • Rebuilt two high-stress bends with extended overlaps in flow direction.

Results (First 12 Months)

  • No observed undercutting or flotation during two peak-flow events; mat remained seated (the “No-Float” advantage).
  • Vegetation density exceeded target by month 4, forming a continuous root-reinforced armor layer.
  • Maintenance calls dropped from quarterly to one post-storm inspection; sediment carry-through at culverts decreased noticeably.

Takeaway: The integrated geogrid + 3D matrix allowed vegetation to establish quickly and resist seasonal shear, transforming a high-maintenance reach into a resilient, green channel.

Specs Snapshot

  • Homogeneous HP-TRM: high-tenacity polyester geogrid + thermally fused 3D nylon monofilaments
  • Shear capacity (vegetated): ≤ 20 psf (application dependent)
  • Slopes: ≤ 0.25H:1V (very steep)
  • Compatible with FGM™ and bonded fiber matrices
  • No-Float material composition resists buoyancy
  • High stiffness, low creep; interacts with granular soils

FAQs

Is EnkaMat R45 a temporary blanket?

No. R45 is a permanent turf reinforcement mat designed to work long-term with established vegetation.

Can I use it under hydraulically applied growth media?

Yes. R45 serves as a stable substrate for FGM™ and bonded fibers, helping them lock in place and accelerate vegetation.

What if my site experiences occasional high water?

The No-Float material composition helps the mat stay seated during high-water events when properly anchored.
