Erosion matting comes in various materials, each suited for different applications. The main types include:

• Straw Matting: Often used for temporary erosion control and is biodegradable.
• Coir Matting: Made from coconut fibers, it’s more durable and suitable for longer-term applications.
• Synthetic Matting: Created from artificial materials, these are long-lasting and used in high-traffic areas.

Material Comparison

Material Type	Durability	Biodegradable	Common Uses
Straw	Short-term	Yes	Temporary sites
Coir	Medium-term	Yes	Steep slopes, streambanks
Synthetic	Long-term	No	Permanent areas, high-traffic regions

Installation Process

Proper installation of erosion matting is essential for it to be effective. Here’s a step-by-step overview:

• Site Preparation: Clear the area of debris and smooth the soil surface.
• Mat Placement: Unroll the erosion matting over the prepared site.
• Securing the Matting: Use stakes or staples to anchor the matting, ensuring it conforms to the surface contours.
• Seeding (if needed): Some projects require seeding before or after mat placement for vegetation growth.

Benefits of Erosion Matting

Erosion matting offers several advantages for construction and landscaping projects, including:

• Prevents soil loss and promotes soil stability.
• Reduces sediment runoff into waterways.
• Facilitates vegetation growth by protecting seeds and young plants.
• Improves aesthetics of construction sites.

Example Use Case

One practical application of erosion matting is on roadway embankments. According to the Environmental Protection Agency (EPA), using erosion matting in these areas can significantly reduce soil erosion and sediment transport, enhancing both road safety and environmental health.

With these components and processes, erosion matting plays a vital role in preventing erosion and maintaining the integrity of construction and natural sites.

Timing of Seeding in Relation to Erosion Control Blankets

Seeding Before or After: The Debate

While erosion control blankets play a significant role in reducing soil erosion, the timing of seeding in relation to the laying of the matting has always been a subject of debate. Seeding, the process of plant propagation, is a key aspect of regenerating plant cover on eroded soils.

Seeding Before Erosion Control Blankets

Placing the seed before laying the erosion control blanket is quite common. This ensures that the seed is in immediate contact with the soil, which promotes higher germination rates. Further, having an erosion control blanket on top protects the seeds from wind, birds, and harsh weather, while maintaining a suitable environment for seed germination and growth.

• Timing: Seeds are sowed as part of the site preparation and before the matting is rolled out.
• Benefit: Cascading protection for the seeds, contributing to higher success of plant colonization.
• Challenge: Unprotected seeds may be prone to birds and wind displacement before mat installation.

Seeding After Erosion Control Blankets

Alternatively, some projects might require seeding after the erosion control blanket is installed. This is typically done for certain blanket types such as the open-weave mesh variety, allowing seeds to slip through the blanket onto the soil.

• Timing: Seeds are scattered after the erosion matting has been secured.
• Benefit: The underlying soil is pre-protected by the erosion blanket, reducing the risk of seed displacement due to wind or rain.
• Challenge: Certain blanket types may inhibit seed-soil contact, potentially impacting germination rates.

Specific Use Case: Wildfire Rehabilitation

A compelling use case for deciding when to seed in relation to erosion matting is during the rehabilitation of wildfire-affected areas. According to the Natural Resources Conservation Service (NRCS), seeding after laying down erosion control blanketing is often the most effective way to restore vegetation in these threatened environments. This is because the mat ensures immediate soil protection, and the applied seeds can take advantage of the protected, nutrient-rich environment for faster and healthier growth.

Deciding Factor: Project Needs

The choice between seeding before or after installing erosion control blankets largely depends on project specifics such as the location, soil type, expected rainfall, seed type, and blanket type. Making the right decision based on these factors can ensure effective erosion control and successful vegetative establishment.

What are the Pros of Erosion Control Mats?
