with water and hydraulically applied as a slurry to reduce soil erosion and aid in vegetation establishment.

1.5SUBMITTALS

A.Authorized Products List (APL) Compliance Form for information.
B.Manufacturer installation instructions and Material Safety Data Sheet for

information.

C.HECP work plan for review, include the following:
1.Description of the measuring technique.
2.Calculated area to receive each Type of HECP
3.Product name, application rate and total quantity of each Type of

HECP to be used.

4.Product name, application rate and total quantity of Tackifier for

HECP Type 1, if required

1.6DELIVERY, STORAGE, AND HANDLING

A.Deliver material and products in original ultraviolet (UV) and weather-

resistant factory labeled packages showing the name of the manufacturer and product description.

PART 2 PRODUCTS

2.1HYDRAULIC EROSION CONTROL PRODUCTS (HECP)

A.Furnish HECP according to Table 1 with components such as

biodegradable wood, wheat, straw or other natural fibrous material that are manufactured through thermal or mechanical process and generally pre-packaged with tackifiers, flocculants, polymers, co-polymers or other binding agents.

B.Use HECP components pre-packed by the manufacturer, with the

following exception:

1.HECP Type 1 products that do not contain a pre-mixed tackifier

require a tackifier to be field mixed into the HECP.

C Factor testing must match the Type 1 Rainfall Intensity, Slope, and Duration Combinations shown in Table 4 in ASTM D 8297 or ASTM D 8298.

Current ASTM D 7322 test results are graded as PASS or FAIL. PASS score indicates that seed germination is > 100% when compared to a control/bare soil sample. FAIL score indicates that seed germination is ≤ 100%.

2.2WATER

A.Free of dirt, silt and other detrimental matter.

2.3TACKIFIER FOR HECP TYPE 1

A.General
1.Nonflammable
2.Nontoxic to aquatic organisms.
3.Functional for a minimum of 90 days.
B.Guar-based tackifier
1.Derived from ground endosperm of guar seeds (Cyamopsis

tetragonolobus) and treated with dispersant agents.

2.Use a rate of 50 lb per acre when required for HECP Type 1

products without tackifier.

Hydraulic Erosion Control Products

C.Psyllium-based tackifier
1.Manufactured from the finely ground muciloid coating of Plantago

ovata or Plantago ispaghula seeds.

2.Will hydrate when mixed with water to form a slurry and produce a

firm, resilient and rewettable membrane on the soil surface after application.

3.Use a rate of 100 lb per acre when required for HECP Type 1

products without tackifier.

D.Starch-based tackifier
1.Typically derived from corn or potatoes in a non-ionic, cold-water

soluble (pre-gelatinized) granular form.

2.Use a rate of 150 lb per acre when required for HECP Type 1

products without tackifier.

PART 3 EXECUTION

3.1PREPARATION

A.Complete required grading and topsoil placement in designated areas

before applying HECP.

B.Measure the area to be stabilized with HECP to calculate the quantity of

HECP required.

1.Coordinate with the Engineer to determine acceptability of the

measuring technique to be used before measuring the areas to be stabilized.

C.Time restrictions of HECP application:
1.Apply HECP within 24 hours after seeding.
2.Apply when soil is dry and rain is not forecasted to occur within 24-

48 hours after HECP application.

3.2PRE-APPLICATION VERIFICATION TEST

A.Apply HECP to 100 yd2 test area in the presence of the Engineer before

beginning HECP application.

1.Begin HECP application after obtaining the Engineer’s

concurrence.

3.3HECP APPLICATION

A.Mix water and HECP according to the manufacturer’s instructions.

Hydraulic Erosion Control Products

B.Apply HECP according to Table 2, unless manufacturer’s recommended

rate is higher than the rate specified.

Table 2 HECP Application (Slope Gradient and Application Rates) Minimum Rate HECP Max. Slope Gradient (H:V) (lb per acre) Type 1 3:1 2,500 Type 2 2:1 3,500 Type 3 1:1 4,000

C.Apply a uniform layer of HECP slurry from a minimum of two opposing

directions to meet manufacturer’s instructions for installed thickness and ground coverage.

1.Use hoses and extensions to apply HECP as required to difficult to

reach locations.

2.Verification test area may be used to visually verify quality of HECP

application.

3.Remove overspray before the HECP slurry dries.
