How to Install Erosion Control Blanket
Types and Materials of Short-Term Erosion Control Blankets
When selecting a short-term erosion control blanket, it’s essential to weigh factors like durability, cost, and environmental considerations. Each type comes with its own strengths and limitations, making it suitable for specific conditions and project needs.
Straw Blankets
Straw blankets are one of the most budget-friendly options for short-term erosion control. Made from weed-free agricultural straw held together with biodegradable netting, these blankets typically last between 3 and 12 months. Their flat fiber structure provides excellent ground coverage and helps retain moisture, which is crucial during the early stages of plant growth. However, they lack long-term stabilization since the fibers don’t interlock once the netting degrades. Straw blankets are best suited for gentle slopes of up to a 3:1 gradient and can handle shear stresses up to 84.0 Pa (1.75 lb/ft²) when constructed with double-netting [6].
Wood Excelsior Blankets
Wood excelsior blankets, like those in the Curlex line, are crafted from Great Lakes aspen wood fibers, a renewable and naturally seed-free resource. These blankets strike a balance between affordability and longevity, lasting anywhere from 12 to over 36 months, depending on environmental conditions. Their curled fibers interlock effectively, maintaining soil stabilization even after the netting breaks down. This design also creates a greenhouse-like environment that supports moisture retention and seed germination [6]. Different grades cater to varying needs: Curlex I is ideal for slopes up to 2:1 (H:V) with a shear stress tolerance of 84 Pa (1.75 lb/ft²), while Curlex II handles steeper slopes up to 1.5:1 (H:V) with a capacity of 108 Pa (2.25 lb/ft²) [6].
Synthetic and Biodegradable Blends
Blended erosion control blankets combine natural fibers with synthetic or advanced biodegradable materials. Coconut fiber (coir) blankets are a premium choice, offering excellent strength and resilience with lifespans of around 2–3 years. These blankets can stabilize slopes as steep as 1:1 and withstand shear stresses of up to 108 Pa (2.25 lb/ft²) [4][6]. Blended options, such as straw–coconut combinations, provide a shear stress capacity of about 96 Pa (2.0 lb/ft²) for slopes up to 1.5:1 (H:V) [6]. Fully biodegradable options, like FibreNet™ (jute netting) and E-Staple® (made from plant sugars and oils), are also available [6]. Some designs use photodegradable polypropylene netting, which breaks down under UV exposure, though shaded portions may persist longer. While synthetic components can improve performance in challenging conditions, they raise concerns about wildlife entanglement and microplastic pollution [1][2].
"The importance of using 100% biodegradable products is paramount with the environmental concerns and regulations we face today." – American Excelsior Company [6]

The use of erosion control blankets has surged, with over 40% of construction and landscaping projects incorporating these solutions. Around 35% of users favor natural-fiber options, which not only support soil health but also align with environmentally conscious practices [5]. This shift highlights a growing commitment to sustainable erosion control methods.
Applications of Short-Term Erosion Control Blankets
Erosion control blankets offer temporary soil stabilization for slopes, construction sites, newly planted areas, and drainage features throughout Maryland. Here’s a closer look at how these blankets help stabilize slopes, shield bare soil, support new vegetation, and protect drainage systems.
Stabilizing Slopes and Embankments
Slopes and embankments can be tricky to manage when it comes to erosion control. Erosion control blankets provide a reliable solution by creating a stable surface that slows water movement, allowing vegetation to take root. Instead of water eroding the soil, it flows over the blanket, protecting the seedbed.
"Erosion control blankets are excellent for hilly regions. If your yard has a hill, rain can push mud, rocks, weeds, and debris downhill. Using an erosion control blanket will stop this process in its tracks by rolling water over the blanket rather than the soil." – Eastgate Supply [7]
Homeowners often use these blankets on hillsides or near waterfronts to prevent soil and debris from washing away during storms. Installation involves clearing debris, seeding and compacting the soil, trenching the top edge, rolling the blanket downhill, and securing it with landscaping staples.
Different types of blankets suit different slopes. For moderate slopes (up to 1.5:1), wood excelsior blankets are a good choice. For steeper slopes with heavy runoff, coconut fiber blankets provide better durability. Compared to loose straw, erosion control blankets stay firmly in place, offering a steady surface for root growth.
These blankets aren’t just for hillsides – they’re also essential for protecting exposed soil after construction.
Protecting Bare Soil After Construction
Construction projects often leave behind large areas of bare soil, which are vulnerable to erosion. Erosion control blankets act as a shield, protecting seedbeds from wind and water while creating the right conditions for seeds to germinate.
By securing seeds, roots, and stems, the blankets prevent them from being displaced by wind or water. This allows vegetation to grow through the blanket’s fibers and establish roots, ensuring long-term soil stability. Once installed, the blanket should remain undisturbed until the vegetation is well-rooted, maintaining its protective role during those critical early stages.
While these blankets are crucial for construction sites, they’re just as effective in helping new vegetation take hold.
Supporting New Lawn and Vegetation Growth
Erosion control blankets create the perfect environment for seed germination and early plant growth. They help retain soil moisture, protect seeds from being washed away by rain, and even deter birds from eating them. This significantly boosts germination rates compared to unprotected seeding.
By balancing moisture and airflow, these blankets prevent both drought stress and waterlogging – common issues that can harm young plants. Homeowners and landscapers frequently use straw erosion blankets for seeding new lawns or repairing damaged patches. These blankets can also be paired with hydroseeding to speed up vegetation growth and improve success rates.
On golf courses, erosion control blankets are used to establish smooth turf on slopes, greens, and fairways. They not only help grass grow but also enhance the course’s appearance and playability. When mowing these areas, it’s important to set mower blades at least 2.5 inches high to avoid damaging the blanket or young seedlings.
Beyond lawns and slopes, these blankets play a key role in stabilizing drainage features.
Use in Drainage Features
Erosion control blankets are highly effective for temporary stabilization in drainage areas such as swales, retention basins, and channel banks. They prevent washouts and reduce the risk of mudslides, which is especially important in Maryland’s climate, where seasonal flooding can be a concern.
As the blankets biodegrade, the vegetation they help establish takes over, providing long-term stabilization. To ensure proper installation, secure the edges every 2 to 3 feet with staples, overlap blankets by 4 to 6 inches, and dig trenches to anchor the material against strong water flows.
For gentle drainage slopes, straw blankets offer about three months of protection. For medium-term projects in sandy or well-drained soils, wood fiber blankets can last up to 12 months. Properly securing the edges is critical in areas prone to high winds or heavy rainfall to keep the blankets intact during storms.
Benefits and Limitations of Short-Term Erosion Control Blankets
Understanding both the advantages and challenges of erosion control blankets can help Maryland property owners make informed decisions about temporary soil stabilization. While these blankets provide effective short-term protection, they come with certain limitations that deserve attention.
Key Benefits
Short-term erosion control blankets offer immediate protection for bare soil, which is essential to the success of many projects. These blankets are typically 90% or more effective at reducing rill, sheet, and wind erosion [3], delivering reliable results right after installation.
One of their standout features is their affordability, making them a practical choice for both homeowners and contractors working on temporary stabilization projects in Maryland.
They also help speed up vegetation growth by retaining soil moisture and stabilizing temperature, creating better conditions for seeds to germinate compared to unprotected soil.
Another key advantage is their biodegradability, which brings both environmental and cost-saving benefits. For instance, ultra short-term blankets start breaking down within a month and achieve 80% decomposition within three months [3][2]. This eliminates the need for removal, saving time and reducing waste.
The installation process is simple and doesn’t require specialized tools or advanced training. This ease of use allows for quicker project completion, which is particularly useful in Maryland’s unpredictable weather conditions.
Potential Limitations
One of the primary drawbacks is their limited lifespan. Straw blankets, for example, can degrade in as little as 45 days [9], meaning they are only suitable for short-term use and require follow-up measures for long-term stabilization.
Slope restrictions also limit their application. Single-net straw blankets are effective on slopes up to 4:1 under moderate runoff, while double-net versions can handle slopes up to 3:1 with medium runoff [8]. However, they are not ideal for steep slopes or areas with high water flow.
The cost-effectiveness of these blankets can diminish if their lifespan doesn’t align with the project’s needs. Using a short-term blanket for a site requiring full-season protection could result in premature failure and additional costs.
Synthetic components in some blankets raise environmental concerns. Non-biodegradable netting can harm wildlife, such as small mammals and reptiles, and may also interfere with early plant growth. Additionally, these materials must be removed to prevent plastic waste [10].
Finally, their performance can fall short in challenging conditions. While effective at reducing sheet and rill erosion on appropriate sites, these blankets do little to manage water flow or reduce runoff volume. They may also lack the strength needed for areas with heavy rainfall or high shear stress [3].

Installation and Maintenance Best Practices
Proper installation and regular upkeep are key to ensuring erosion control blankets perform effectively throughout their lifespan.
Step-by-Step Installation Process
Start by clearing debris and grading the surface to create a smooth, even slope.
When placing anchors, ensure correct spacing and depth. Install them every 3–4 feet along the edges and 6–8 feet within the blanket. For steeper slopes (greater than 3:1), reduce spacing to 2–3 feet. Anchors should be driven at least 6 inches into the soil to secure the blanket firmly.
Overlap adjacent blankets by 4–6 inches, and secure the seams with anchors every 2 feet. This overlap prevents water from seeping underneath and destabilizing the installation. Begin at the top of the slope and work downward, keeping the material taut but not stretched.
For seeding integration, apply seed evenly on the prepared soil before laying the blanket. This ensures the seed has good soil contact, retains moisture, and receives adequate light for germination.
Once the blanket is installed, ongoing monitoring is essential to maintain its effectiveness.
Monitoring and Maintenance Tips
After installation, regular inspections are vital for long-term performance. Conduct weekly checks during the first month to catch potential issues early. Look for loose anchors, torn material, or areas where the blanket has lifted from the soil. Pay close attention to edges and seams, as these are common trouble spots.
After heavy rainfall or strong winds, weather-related inspections are critical. Look for washout areas, which appear as depressions or gaps under the blanket. Address these immediately to prevent further erosion.
Vegetation growth typically begins within 2 to 4 weeks under favorable conditions. Monitor the area to ensure plants are sprouting evenly. Sparse or uneven growth may signal poor seed-to-soil contact or insufficient moisture in certain areas.
Check for displaced or loose anchors regularly, especially after freeze-thaw cycles. Replace missing anchors promptly and ensure all fasteners remain flush with the blanket surface to prevent damage or snagging.
Document the installation date and track the blanket’s expected lifespan based on its type. For example, straw blankets generally last 3 to 12 months, while wood excelsior blankets can remain effective for 12 to 24 months before degrading significantly.
Post-Use Considerations
Once the blanket has served its purpose, the final step involves managing its post-use phase.
In most cases, erosion control blankets do not need to be removed after vegetation is established. According to CVTS Landscaping:
"You don’t have to remove the erosion control blanket. As long as it’s not causing an obstruction (which it shouldn’t), there’s no reason to get rid of it. In fact, you can leave it there for grass and other plants you intend to grow later on down the road." [11]
The material will naturally decompose over time, with breakdown periods ranging from 3 months to 3 years, depending on the blanket’s composition and environmental factors [11][3]. Straw blankets degrade the fastest, while wood excelsior and coconut fiber options last longer, gradually integrating into the soil.
In some cases, wildlife interactions may require attention. Long-lasting blankets can occasionally hinder small mammals or burrowing animals [3]. If this becomes an issue, replace those sections with shorter-term solutions like straw mulch or hydromulch.
For blankets with permanent netting, the netting continues to provide erosion control even after the organic materials decompose [11]. This feature supports long-term vegetation growth without the need for replacement or additional stabilization.
As the blanket degrades, monitor the transition to ensure vegetation is well-established. Once plant root systems are strong enough to stabilize the soil, the blanket’s role naturally shifts to supporting permanent erosion control through the vegetation itself.

FAQs
What factors should I consider when choosing an erosion control blanket for my project?
Choosing the right erosion control blanket involves weighing several important factors, such as soil type, slope steepness, climate, and the project’s timeline. If you’re working on short-term stabilization, materials like straw, coir, or wood fiber are solid options. On the other hand, coconut fiber blankets are better suited for long-term protection, especially in tougher environmental conditions.
It’s important to tailor your choice to the specific demands of your project to avoid spending more than necessary or overcomplicating the solution. For instance, steeper slopes or areas prone to heavy rainfall often need sturdier materials, while flat or gently sloping terrain may perform well with lighter options. Aligning the blanket’s durability and functionality with your site’s conditions will ensure you get the most effective results.
What are the environmental effects of synthetic materials in erosion control blankets?
Synthetic materials used in erosion control blankets can have lasting negative effects on the environment. One major concern is that many of these materials are non-biodegradable. Once they’re in the soil, they don’t break down easily, leading to persistent plastic pollution. Over time, this pollution can disrupt local ecosystems and degrade soil quality.
Another issue is the danger synthetic components, like plastic netting, pose to wildlife. Birds, reptiles, and small animals often get tangled in the netting, which can lead to injuries or even fatalities. Opting for biodegradable or wildlife-safe materials is a much better choice, offering effective erosion control without causing harm to the environment or its inhabitants.
What’s the best way to install and maintain erosion control blankets for short-term use?
To get the most out of erosion control blankets, begin by prepping the ground carefully. Remove any debris, and make sure the surface is firm and as level as possible. When it’s time to install, follow the manufacturer’s instructions closely, anchoring the blanket securely with stakes or staples to keep it in place, even during heavy rain or strong winds.
Once installed, keep a close eye on the blankets, especially after storms. Look for any signs of damage or areas where the blanket might have shifted. If you spot any problems, take immediate action to repair or replace the affected sections. Consistent maintenance is key to ensuring the blanket performs well and lasts as long as possible.
