Erosion Control Blankets
Temporary Erosion Control Blanket (ECB) -Class I & II

For any ECB that has netting attached, the netting shall be photodegradable and/or biodegradable as
specified for that Class and type of ECB. The weight of the netting shall not exceed 15% of the total
blanket weight.

    Class I: Short-term Degradable Products - Defined as products composed primarily of biologically,
    photochemically or otherwise degradable constituents with longevity of approximately 1 year. Non-
    organic, photodegradable or biodegradable netting is allowed.

    Type A- Maximum Product Permissible Shear Stress (0-1.0 lb/ft2):
    A single or double netted product for use on slopes 3H: IV and flatter where the calculated design
    shear stress is 1.0 lb/ft2 or less. Not to be used in channels.

    Type B- Maximum Product Permissible Shear Stress (1.0 - 1.7 lb/ft2):
    A double netted product, used on slopes 2.5H: IV or flatter or in channels where the calculated design
    shear stress is 1.7 lb/ft2 or less.

    Class II: Long-term Degradable Products- Defined as double netted products composed primarily of
    biologically, photochemically or otherwise degradable constituents with a longevity of up to 3 years.

    Type A- Maximum Product Permissible Shear Stress (0 - 2.0 lb/ft2):
    For use on slopes 2H: IV or flatter or, in channels where the calculated design shear stress is 2.0 lb/ft2
    or less. Non-organic, photodegradable or biodegradable netting is allowed.

    Type B- Maximum Product Permissible Shear Stress (0 - 2.0 lb/ft2):
    For use in environmentally sensitive areas on slopes 2H:1V or flatter or, in channels where the
    calculated design shear stress is 2.0 lb/ft2 or less. Only organic fiber woven mats are allowed with a
    maximum opening of 1/2-inch (12 mm).

Turf Reinforcement Mats
Class III TRM products and their physical properties are identified in the following tables.

    Class III: Non-degradable Products- defined as products composed of non-degradable constituents
    with an unlimited longevity.

    Type A- Maximum Product Permissible Shear Stress (0 - 4.0 lb/ft2)*:
    A TRM mat for use on slopes 2H: IV or flatter or, in channels where the calculated design shear stress
    is 4.0 lb/ft2 or less.

    Type B- Maximum Product Permissible Shear Stress (4.0 - 8.0 lb/ft2)*:
    A TRM mat for use on slopes 1H: IV or flatter or, in channels where the calculated design shear stress
    is 8.0 lb/ft2 or less.

    Type C- Maximum Product Permissible Shear Stress (8.0 - 10.0 lb/ft2)*:
    A TRM mat for use on slopes 1H: IV or steeper or, in channels where the calculated design shear
    stress is 10.0 lb/ft2 or less.

* The maximum permissible shear stress values must be the result of large-scale performance testing
  conducted at a recognized third party facility.

Notes:
1.   Values for machine and cross machine directions, respectively, under dry or saturated conditions. Minimum average roll values are
     calculated as the typical minus two standard deviations. Statistically, it yields a 97.7% degree of confidence that any samples taken from
     quality assurance testing will exceed the value reported.
2.   Formerly test method ASTM D1682.
3.   Modified ASTM D1777 using 6” Pressure Plate and 0.2 kPA.
4.   Ground Cover Factor represents “0/0 shade” from Lumite Light Projection Test.

Notes:
5.   Values for machine and cross machine directions, respectively, under dry or saturated conditions. Minimum average roll values are
     calculated as the typical minus two standard deviations. Statistically, it yields a 97.7% degree of confidence that any samples taken from
     quality assurance testing will exceed the value reported.
6.   Formerly test method ASTM D1682.
7.   Modified ASTM D1777 using 6” Pressure Plate and 0.2 kPA.
8.   Ground Cover Factor represents “0/0 shade” from Lumite Light Projection Test.
