If seeding is performed with cultipacker-type seeder or by hydroseeding, rolling may be eliminated.

3.2.8 Erosion Control Matting

The Contractor shall place erosion control matting on all dike embankment repair areas at DA 26 Borrow Area extending from the toe of the outside side slope, over the top of the dike embankment, and down the inside side slope 2 feet below the top of dike elevation. Placing of matting shall be done immediately following seeding and mulching. The earth surface shall be smooth and free from stones, clods, or debris which will prevent the contact of the matting with the soil. Care shall be taken to preserve the required line, grade, and cross section of the area covered.

Matting shall be unrolled in the direction of the flow of water, and shall be applied without stretching so that it will lie smoothly but loosely on the soil surface. The up-channel or top of slope end of each piece of matting shall be buried in a narrow trench at least 5 inches deep and tamped firmly. After the end of the matting is buried, the trench shall be closed and tamped firmly. Where one roll of matting ends and a second roll begins, the end of the upper roll shall be brought over the buried end of the second roll so that there will be a 6 inch overlap. Check slots shall be constructed at each 50 feet longitudinally in the matting or as directed by the Contracting Officer and/or his or her designated representative.

These slots shall be narrow trenches at least 5 inches deep. The matting shall be folded over and buried to the full depth of the trench, after which the trench shall be closed and firmly tamped. Where 2 or more widths of matting are laid side by side, the overlap shall be at least 4 inches.

Staples shall be placed across matting at ends, junctions, and check slots and shall be spaced approximately 10 inches apart. Staples shall be placed along the outer edges and down the center of each strip of matting and shall be spaced 3 feet apart. After jute matting has been placed and stapling completed, the matting shall be rolled with an approved roller to assure that it is in proper contact with the soil and mulch. The installation of erosion control matting on cut or fill slopes the Contracting Officer and/or his or her designated representative may require adjustments in the trenching or stapling requirements to fit individual slope conditions.
