Erosion Control Blankets Explained
What Are Erosion Control Blankets?
Erosion control blankets are designed to stabilize soil, prevent erosion, and encourage vegetation growth. These blankets are made from natural or synthetic fibers woven into mats that are placed directly on the soil surface.
- Straw blankets are the most affordable option, breaking down within 3–12 months[1]. They are ideal for quickly establishing vegetation.
- Coconut coir mats stand out for their strength and durability, naturally decomposing over 2–5 years[1], making them perfect for areas needing deeper root systems.
- Jute netting is lightweight and fully biodegradable, offering short-term protection in areas with minimal erosion risk.
For more demanding conditions, synthetic blankets combine polypropylene or polyethylene fibers with natural materials to boost durability, especially in extreme weather. Meanwhile, straw/coconut mix blankets strike a balance between affordability and durability by blending the strengths of both materials[2].
Choosing the right material depends on the specific needs of the site, which we’ll explore further.
How Erosion Control Blankets Are Used
Erosion control blankets are effective at reducing water flow across surfaces[3]. By slowing stormwater runoff, they lessen its erosive power and help prevent rills and gullies from forming. Beyond erosion prevention, these blankets act as a mulch layer, supporting seed germination and retaining soil moisture[4].
Proper installation is key to their success. Here’s how to do it:
- Clear debris and smooth the soil surface with a rake[4].
- Spread seeds on the soil before laying the blanket[4].
- Secure the blanket into the slope by digging a small trench at the top[3].
- Overlap the upwind edges under adjacent blankets to ensure stability[3].
These methods are especially important in managing Maryland’s varied weather and soil conditions.
Pros and Cons of Erosion Control Blankets
| Advantages | Limitations |
|---|---|
| Affordable option for stabilizing slopes[3] | Straw blankets may lack strength for steep slopes or heavy rain[1] |
| Adaptable to different terrains[3] | Jute netting has a shorter lifespan compared to other materials[1] |
| Biodegradable natural materials decompose over time[3] | Synthetic options are less environmentally friendly[1] |
| Reduces sediment runoff, protecting downstream areas[4] | Requires careful installation for best results |
The durability of these blankets ranges from 45 days to over three years, depending on the material and environmental factors[4]. For Maryland’s diverse landscapes, sandy soils in coastal plains benefit from lightweight straw or coir blankets[1], while the heavier clay soils of the Piedmont region require sturdier coconut mats[1]. Areas with frequent heavy rainfall need more durable, long-lasting blankets[1], and steep slopes are best suited for coconut fiber options, whereas lighter straw materials work well on gentler slopes[1]. This range of options allows for tailored solutions that balance performance and cost across Maryland’s varied terrain.
Geotextiles for Erosion Control
What Are Geotextiles?
Geotextiles are specialized permeable fabrics widely used in civil engineering and environmental projects to stabilize soil, control erosion, and improve drainage systems [7]. Unlike erosion control blankets that sit on the surface, geotextiles are embedded within the soil, offering long-term stability and protection.
These fabrics come in three main types – woven, non-woven, and composite – each designed for specific tasks:
- Woven geotextiles are created by weaving synthetic fibers, resulting in strong, durable fabrics with low permeability. They are excellent for soil separation, reinforcement, and load support. However, their tight weave limits filtration capabilities. Monofilament woven types deliver both strength and filtration, while slit film variants are ideal for stabilization but allow minimal water flow [5].
- Non-woven geotextiles are made by bonding fibers through mechanical, thermal, or chemical methods. Needle-punched versions are breathable and versatile, while heat-bonded types offer greater stability with less fiber movement [5].
- Composite geotextiles combine woven and non-woven layers, providing a balance of reinforcement and filtration [5].
This adaptability makes geotextiles a key tool for tackling erosion in a variety of settings.
How Geotextiles Are Used
Geotextiles play a critical role in preventing erosion, strengthening soil layers, and improving drainage. By acting as a filter, they allow water to pass through while keeping soil particles in place, which is especially important for areas with diverse soils and frequent storms, like Maryland [7].
In soil stabilization, geotextiles enhance load-bearing capacity by separating and reinforcing soil layers. For instance, during the I-85 road widening project in Georgia, slit film geotextiles were used to prevent subgrade mixing, leading to a 20% improvement in base stability compared to untreated areas [5].
For drainage, geotextiles serve as filters that prevent fine particles from clogging systems, ensuring efficient water flow [7]. They also protect geomembranes in landfill liners or act as barriers in reservoirs and ponds. When paired with vegetation or engineered structures, geotextiles can fortify steep or unstable slopes [9].
Installation typically involves placing non-woven fabric beneath a layer of soil or aggregate [8]. Local suppliers in Maryland provide a range of geotextile options to address the region’s erosion challenges effectively.
Pros and Cons of Geotextiles
Here’s a breakdown of their benefits and limitations:
| Advantages | Limitations |
|---|---|
| Durable for long-term erosion control projects [10] | Higher cost compared to landscape fabric and erosion blankets [10] |
| Performs multiple roles – filtration, separation, reinforcement, and drainage [7] | |
| Woven types offer high strength for load-bearing needs [5] | |
| Non-woven types excel in filtration and drainage [5] | |
| Suitable for a wide range of applications [9] |
Choosing the right geotextile depends on the project. Woven geotextiles are assessed by their tensile strength, making them ideal for stability and reinforcement. Non-woven geotextiles, on the other hand, are categorized by weight and are better suited for filtration and drainage tasks [6].
Geotextiles are a durable and reliable option for erosion control, especially for projects requiring long-term solutions. Their ability to work below the surface ensures consistent protection, even in areas with harsh weather and varying soil conditions [10].

| Lifespan | Designed to biodegrade within 6 to 24 months as vegetation takes root [11] | Built to last for several years or even decades, ideal for permanent applications [14–15] |
| Application Scenarios | Best for slopes, newly seeded areas, temporary stabilization, and promoting rapid vegetation growth [11] | Ideal for soil separation, reinforcement, filtration, drainage systems, and use under roadways or retaining walls [14–15] |
| Installation Complexity | Lightweight and easy to install – roll out and secure with stakes or staples [11] | Installation can be more complex, requiring precise placement, overlapping, and anchoring; may need professional expertise [14–15] |
| Cost | Lower upfront cost per square foot [11] | Higher initial cost but provides long-term value for permanent projects [14–15] |
The key distinction lies in their purpose: erosion control blankets are temporary and biodegrade as vegetation stabilizes the soil, while geotextiles offer long-lasting structural support.
How to Choose the Right Option
Choosing between erosion control blankets and geotextiles depends on factors like project duration, soil type, site conditions, and budget. Each has its strengths, making them suitable for different scenarios.
For temporary stabilization, erosion control blankets are the go-to choice. They work well on steep slopes with rapid runoff, offering immediate protection and encouraging vegetation growth [11]. On the other hand, permanent solutions requiring soil reinforcement or structural stability – such as under driveways or retaining walls – are better suited for geotextiles [14–15].
Soil type also plays a role. For heavy clay soils prone to waterlogging, geotextiles provide effective filtration. Meanwhile, sandy soils that need surface stabilization benefit from erosion control blankets. Additionally, projects with drainage requirements often rely on geotextiles because of their engineered permeability [14–15].
Budget considerations are equally important. While erosion control blankets typically cost less upfront, geotextiles may deliver better value over time due to their durability. Always ensure the products you choose meet Maryland Department of Transportation standards [12].
