Erosion control matting has become a popular temporary solution for work zones that have advanced erosion and sedimentation. The two most popular solutions employed by environmental consultants are erosion control blankets (ECBs) and turf reinforcement mats (TRMs).
Thanks to advances in synthetic matting, turf reinforcement mats are capable of providing long-term site stabilization on slopes and surfaces that struggle to establish proper vegetative cover.
Both erosion control blankets and turf reinforcement mats are excellent tools to control erosion over large surface areas, but choosing the right one comes down to specific site conditions and your intended timeline.
If you are looking for erosion control matting for your work site or property, this guide will provide a detailed breakdown of popular types of mats to help you decide on the right one.
What Are Erosion Control Mats?
Erosion control mats are protective layers placed over the soil to prevent erosion caused by wind, water, and human activity. These mats help keep soil intact while allowing vegetation to establish on the surface.
Erosion control mats are most commonly used in road construction, landscaping, stormwater management, and infrastructure projects, though they have nearly endless applications.
Depending on the type of mat you choose, they will consist of biodegradable or synthetic fibers based on their intended use life.
Let’s break down each type of mat to help you understand key differences and choose the right mat for your project.
Erosion Control Blankets (ECBs)
Erosion Control Blankets (ECBs) are popular erosion control solutions that provide temporary cover to exposed surfaces until vegetation can be established. These mats consist of biodegradable materials that are porous enough to allow for ground infiltration while also keeping exposed soils intact.
ECBs are temporary solutions as they will degrade with time, typically within 3-36 months, depending on environmental conditions.
Key Features of ECBs
- Biodegradable Materials: Made from straw, coconut fiber, wood excelsior, or a blend of natural fibers that protect the soil underneath and naturally degrade without harming the soil.
- Temporary Protection: Designed to last from a few months to a couple of years, depending on environmental conditions, providing a cost-effective solution to erosion control.
- Encourages Vegetation Growth: ECBs help seeds and young plants take root by maintaining soil moisture and preventing washouts.
- Easy Installation: Simple to roll out and secure with stakes or staples.
Best Applications for ECBs
- Newly seeded slopes
- Roadside projects
- Residential Landscaping
- Construction site stabilization
- Temporary erosion control on disturbed soil
Turf Reinforcement Mats (TRMs)
Turf Reinforcement Mats (TRMs) provide permanent or semi-permanent erosion control for surfaces with advanced erosion that have difficulty establishing ground cover.
These mats are typically made from synthetic, biodegradable, or composite materials that reinforce vegetation growth while preventing soil erosion.
TRMs are very popular among ditches, streambanks, and high-flow drainage channels that may be difficult to protect with traditional ECBs.
Key Features of TRMs:
- Long-Term Durability: TRMs are designed for permanent use and can last for years without the need for replacement.
- High Strength: TRMs are made from synthetic fibers, polypropylene, or a blend of natural and synthetic materials that are safe for the environment and protect the soil underneath.
- Vegetation Reinforcement: TRMs support plant roots, helping them establish a deep and durable network.
- Heavy-Duty Performance: Ideal for areas with high water flow, steep slopes, and regions susceptible to extreme erosion.
Best Applications for TRMs
- Streambanks and shorelines
- High-flow drainage channels
- Steep slopes and embankments
- Roadside ditches
- Golf courses and parks
Differences Between Turf Reinforcement Mats and Erosion Control Blankets
While both TRMs and ECBs generally serve the same purpose, their material construction and durability will determine which mat is right for you.
| Turf Reinforcement Mats (TRMs) | Erosion Control Blankets (ECBs) | |
| Longevity | Permanent or semi-permanent | Temporary (months to years) |
| Material | Synthetic, composite, or hybrid | Biodegradable natural fibers |
| Strength | High, can withstand heavy flows | Moderate, suitable for light erosion |
| Vegetation Support | Reinforces mature vegetation | Supports early-stage growth |
| Installation Complexity | Moderate to high | Easy to moderate |
| Applications | High-stress, steep slopes, water channels | Temporary stabilization, seeding support |
Choosing the Right Erosion Control Mat
Selecting the appropriate erosion control mat depends on factors such as the intended location, severity of erosion, site conditions, project duration, and environmental impact. Consider the following when choosing between TRMs and ECBs:
- Project Duration: Opt for turf reinforcement mats if a longer-term erosion control solution is required. However, most short-term construction projects can get away with using a temporary erosion control blanket.
- Slope and Water Flow: TRMs are better for steep slopes and areas with heavy water flow, which require more durable fibers, such as synthetic materials.
- Material Preference: If using biodegradable materials is a priority, ECBs made of straw, coconut, or wood fibers are ideal. If long-term reinforcement is needed, TRMs with synthetic components are better.
- Budget Considerations: ECBs are often more cost-effective for short-term projects, while TRMs may have a higher upfront cost but provide long-term benefits.
Erosion control matting is an essential component of erosion control, and deciding on a turf reinforcement mat vs. an erosion control blanket primarily depends on the budget and duration.
In addition to erosion control matting, we recommend investing in alternative erosion control barriers, such as mulching, hydroseeding, and silt fences, to follow proper environmental guidelines.
FAQs
How long do erosion control blankets last?
Erosion control blankets typically last between 12 to 36 months, depending on the material used and environmental conditions. They are designed to biodegrade over time as vegetation establishes.
Are turf reinforcement mats reusable?
TRMs are permanent or semi-permanent solutions and are not meant to be removed and reused. However, they are designed to provide long-term soil stabilization and vegetation reinforcement.
Can erosion control blankets be used on steep slopes?
Yes, but they are best suited for moderate slopes. TRMs are a better choice for steep slopes and areas with high water flow due to their higher durability and reinforcement capabilities.
