Profile® Hydraulic Erosion Control Systems

Hydraulic
Erosion Control

Protect exposed soil, establish vegetation, and reduce erosion risk
with hydraulically applied systems matched to the slope, rainfall
exposure, soil conditions, and performance demands of the project.

Vegetation Is Permanent Erosion Control

Protect the Surface While Vegetation Takes Hold

Disturbed soil is vulnerable from the moment grading is complete.
Rainfall impact, runoff, drying, and seed displacement can compromise
establishment before vegetation has a chance to provide lasting protection.
Hydraulic erosion control systems create an integrated surface layer that
protects the seedbed and supports the development of dense vegetation.

01

Surface Protection

Applied fibers absorb rainfall impact and help limit soil particle
detachment across exposed slopes and disturbed areas.

02

Seedbed Security

The hydraulic matrix helps hold seed and amendments in contact with
the soil rather than allowing them to move with wind or runoff.

03

Moisture Management

Fibers retain moisture around the seedbed and help create more
favorable conditions during germination and early establishment.

04

Efficient Installation

Hydraulic application provides efficient coverage across large,
steep, irregular, or difficult-to-access areas.

Start With the Site

The System Must Match the Erosion Risk

Hydraulic erosion control selection should begin with the conditions
the system must withstand. A short, protected slope does not require
the same performance as a long embankment exposed to intense Florida
rainfall and concentrated runoff.

Slope gradient, slope length, soil erodibility, drainage patterns,
installation season, vegetation requirements, and expected exposure
period all influence the appropriate system.

Color is not performance.

Two hydraulically applied products may look similar immediately
after installation while providing very different levels of
erosion resistance, moisture management, and matrix integrity.

01

Slope Geometry

Evaluate gradient, slope length, transitions, benches, and areas
where runoff can gain speed.

02

Rainfall Exposure

Consider storm intensity, seasonal installation timing, and the
length of exposure before vegetation matures.

03

Runoff Conditions

Identify sheet flow, drainage outlets, low points, slope breaks,
and locations subject to concentrated water.

04

Soil and Vegetation

Review soil condition, seed selection, amendments, fertility,
establishment goals, and maintenance expectations.

Hydraulic Erosion Control Selection

Increase Performance as Site Demands Increase

Conventional hydraulic mulch can support germination on lower-risk areas.
Engineered Fiber Matrix and Flexible Growth Medium technologies provide
progressively greater matrix strength, soil coverage, and erosion-control
performance for more demanding sites.

Performance Level 01

Conventional Hydraulic Mulch

Supports seed placement and moisture retention where erosion
exposure is limited.

  • Relatively flat areas
  • Short, protected slopes
  • Low runoff potential
  • Basic vegetation establishment

Performance Level 02

Bonded or Tackified Mulch

Adds surface adhesion and improved resistance to rainfall and
shallow sheet flow.

  • Moderate slope exposure
  • Longer establishment periods
  • Improved surface bonding
  • Moderate erosion risk

Performance Level 03

ProMatrix™ EFM™

An Engineered Fiber Matrix for projects requiring a meaningful
step above conventional hydraulic mulch.

  • Moderate-to-demanding slopes
  • Enhanced matrix integrity
  • Improved erosion resistance
  • Efficient hydraulic application

Performance Level 04

Flexterra® HP-FGM™

A high-performance Flexible Growth Medium for severe exposure
and demanding vegetated erosion-control applications.

  • Steep or long slopes
  • High rainfall exposure
  • Demanding erosion risk
  • High-performance vegetation establishment
Featured Hydraulic Erosion Control Systems

Two Levels of Performance.
One Site-Specific Decision.

ProMatrix™ EFM™ and Flexterra® HP-FGM™ provide engineered
hydraulic erosion control for projects where conventional mulch
may not deliver enough protection. The right system depends on
slope geometry, rainfall exposure, soil conditions, vegetation
goals, and the consequence of failure.

Engineered Fiber Matrix

ProMatrix™ EFM™

ProMatrix™ Engineered Fiber Matrix™ provides an intermediate hydraulic erosion-control solution between conventional mulches and
higher-performance Flexible Growth Media.

Its engineered fiber structure is designed to create more complete surface coverage, support moisture retention, and improve resistance to rainfall impact and shallow runoff while vegetation establishes.

ProMatrix is well suited for projects that need stronger performance than standard mulch without automatically moving to the highest
performance category.

High-Performance Flexible Growth Medium

Flexterra® HP-FGM™

Flexterra® High Performance-Flexible Growth Medium™ is designed for demanding sites where erosion-control performance and vegetation establishment must work together.

The hydraulically applied medium forms an intimate bond with the soil surface and creates a structured growth environment that supports seed, moisture, and early vegetation development.

Flexterra is the stronger choice for steep slopes, long slope lengths, intense rainfall exposure, difficult soils, and other applications where failure carries greater cost or schedule risk.

ProMatrix or Flexterra?

Match the Technology to the Consequence of Failure

Both systems support vegetation establishment and erosion control.
The appropriate choice depends on slope geometry, rainfall exposure,
soil conditions, project duration, specification requirements, and
the level of risk the site can tolerate.
