What are erosion control blankets and what do they do?
These are mats made of natural or synthetic fibers, used to cover exposed soil and prevent erosion caused by wind, rain, and water runoff. They create a barrier and promote seed germination and plant growth.
4
What are the different types of erosion control blankets?
Biodegradable: Made from natural materials like straw, coconut fiber, or jute, decomposing over time.
Photodegradable: Synthetic fibers with UV stabilizers, degrading after sunlight exposure.
4
What are the erosion control blankets made out of?
Typically, these blankets include an inside material that is held in place by netting on the outside. Standard plastic green netting or biodegradable jute netting can be used for the outside netting. Straw, coconut or a combination both can be used for the material.
4
Can you mow over a erosion control blanket?
Straw is still useful for assisting grass seeds in germinating and taking root, although it, like grass seed, is susceptible to blowing away. If you do choose to mow over it, wait until you can cut over the grass before doing so, or you risk taking out the newly germinated grassroots and all.

What is the difference between Jute and Standard netted erosion control blankets?
Jute and standard netting erosion control blankets are similar in that they both consist of a biodegradable mesh or netting that is laid over the soil and then covered with a layer of mulch. The main difference between the two is the material of the netting.
Jute netting is made from a natural, biodegradable plant material which is obtained from the stem of the jute plant. It is a biodegradable, eco-friendly and sustainable option.
Standard netting, on the other hand, is made from synthetic materials, such as polypropylene or polyethylene. Standard netting is durable and long-lasting, but it is not biodegradable like jute netting.
The choice between jute or standard netting will depend on the specific site and the desired outcome. For example, jute netting may be a better choice for sites where biodegradability is important, while standard netting may be a better choice for sites where durability is a priority.
It's always recommended to consult with a professional or an expert in erosion control to determine the best solution for your specific site.

Are erosion control blankets eco-friendly?
Biodegradable and photodegradable options have minimal environmental impact after decomposition. Choose the appropriate type based on long-term needs and site conditions.
4
Do I need professional help to install erosion control blankets?
Simple projects might be manageable, but for complex situations, slopes exceeding 3:1, or large areas, consulting a professional for proper selection, installation, and maintenance is recommended.
1
What are double net blankets used for?
A double net erosion control blanket is different from a single net blanket in that it provides an additional layer of protection for the soil. The double net design includes one layer of netting that is laid over the soil, and then a second layer of netting is laid over the first layer. This second layer helps to hold the mulch in place and provides additional reinforcement to help prevent erosion. This design allows for better soil stability and erosion control than a single net blanket.
1
When should I use erosion control blankets?
On slopes, embankments, shorelines, new construction sites, and disturbed areas to prevent soil loss.
1
What are the different sizes and thicknesses of erosion control blankets available?
Sizes vary depending on the manufacturer and application, typically ranging from 8ft x 112ft to 16ft x 112ft. Thicknesses depend on material and function, usually between 0.25in and 2in.
1
What are the benefits of using erosion control blankets?
Reduce soil erosion, promote vegetation growth, improve water quality, enhance aesthetics, and control dust.
3
What type of erosion control blanket should I use depending on my slope?
Very steep: Double net with straw/coconut fiber for extra reinforcement and ground cover.
Moderate/gentle: Single net with straw/coconut fiber for basic control and cover.
Low slope/minimal erosion: Standard or jute net with straw/coconut fiber for basic needs.

How do I install erosion control blankets?
Prepare the soil surface, anchor the blanket securely using staples or stakes, overlap edges, and seed the area if desired. Specific installation methods vary depending on the type of blanket and slope.
4
How long do erosion control blankets last?
Biodegradable blankets last 1-2 years, photodegradable 3-5 years, and permanent blankets several years or even decades.
4
Do you pick up straw after grass grows?
Even after the grass seeds have germinated, you shouldn’t have to remove the straw since it will decay by itself. Raking it off puts the roots and leaves of the young plants at risk. If you decide to wait, keep a watch out for weeds growing among your grass seeds.
4
What is the grass that is growing from the straw?
If you didn't self seed before laying the blanket, you may see a type of grass stemmed from POA grass seeds in the straw which may find their way into farmers' fields during plowing. BMP Supplies sources our straw from local Alberta farms, and the only noxious weed of concern in this region is Canada Thistle, which is not present in our products.
The inclusion of native POA grass seeds can actually be beneficial for soil stabilization and erosion control. All BMP Supplies straw is weed free so no invasive species are present in the Wattles. Lab results can be provided upon request.
