How do you lay an erosion mat?
Lay the top of the erosion-control blanket in the trench so that it lies flat against the bottom. When you do this, the roll of blanket should be on the side of the trench away from the slop. This will allow the blanket to cover the trench when it is unrolled onto the slope.
What is the best erosion control blanket?
Coconut/straw blankets are typically recommended for areas that require higher flow rates, steeper slopes, or longer-term use. Since coir is typically longer lasting and stronger than straw, these blankets are able to accommodate areas with significantly higher flows or steeper slopes.
How do erosion control mats work?
Erosion control blankets are installed to help slow down the flow of water across the surface. They do a good job in catching water as it goes down the slope. Wattles can be made out of straw, and as time passes, it blends in with the soil and adds moisture.
What is erosion matting?
Erosion control matting is a stabilization fabric offered by Erosion Control Products and designed to support plant growth and reinforce soil in many erosion control project sites. Made from a range of both natural and synthetic materials, these mats are able to support banks until vegetation is able to take root.
How do I install Excelsior matting?
Step 1: Prep the soil for seed. Loosen up any hard areas at least 2″ deep providing a soft seed bed. Step 2: Install your seed, lime, and starter fertilizer. Step 3: Cover with your matting and staple in with sod staples.
How long does it take for erosion control blanket to degrade?
An erosion control blanket made from straw. The net backing on each blanket should consist of cotton string or polypropylene mesh. For Category 1 blankets, the net backing should start to decompose after one month with 80 percent breakdown occurring within three months.
Where are erosion control blankets used?
Typically, companies use TRMs for applications involving water control, such as in channels or ditches, on the sides of steep slopes, around the banks of streams, on shorelines and any other areas where there are strong erosive forces. These mats help protect the landscape, reinforce plant life and stabilize the soil.
What is soil matting?
Definition. The installation of a protective covering (blanket) or a soil stabilization mat on a prepared planting area of a steep slope, channel or shoreline. Purpose. To aid in controlling erosion on critical areas by providing a microclimate which protects young vegetation and promotes its establishment.
What is turf reinforcement mat?
Turf reinforcement mats (TRMs) are synthetic, non-degradable soil and seedbed covers of variable thickness designed to provide short-term protection against raindrop and wind erosion, permanent support for vegetation on slopes, and permanent armoring and vegetation support for ditches, swales, and channels.
What is a straw mat?
a straw mat: a rug, a carpet made out of dried stalks or grass. noun.

What size erosion control mats do I Need?
NON-CHANNEL EROSION CONTROL MAT INSTALLATION • Staples used for erosion mats shall be 1-2 inch wide, U-shaped, made of No.11 (3.05mm) or larger diameter steel wire, and not less than 6 inches long for firm soils and 12 inches long for loose soils. • In areas with mowed turf or where animal entrapment is possible, use urban mats.
What is base level erosion?
A base level erosion is an imaginary surface of irregular shape, inclined toward the lower end of the principal, or trunk, the stream of a basin, under which the stream and its tributaries were presumed to be unable to erode.
What is an erosion control BMP?
Erosion control BMPs are designed to limit off-site effects of erosion, aid in project construction while minimizing overall cost, and to comply with federal, state, and local laws and regulations. BMPs can be generally classified into two categories, erosion control and sediment control.
What is an erosion blanket made of?
EroNet™ P300® Permanent Erosion Control Blankets The P300® permanent erosion control blanket consists of UV-stabilized polypropylene fiber stitched between heavy- weight UV-stabilized polypropylene top and bottom nets. These mats reduce soil loss and protect vegetation from being washed away or uprooted, even under high stress.
