(2) Consecutive rolls. Shingle and overlap consecutive rolls 2 to 6 in. (50 to 150 mm) in the direction
of flow. Secure staples through seam at 1 R. (300 mm) intervals.
(3) Check seam. Construct astake/staple check seam along the top edge of RECPs for slope
application and at specified intervals in a channel by installing two staggered rows of stakes/staples 4
in. (100 mm) apart on 4 in. (100 mm) centers.
(4) Slope interruption check slot. Excavate a trench measuring 6 in. wide by 6 in. deep (150 x 150
mm). Secure product to the bottom of the trench. Fold product over upstope material and fill and
compact the trench on the downslope side of check slat and seed fill. Continue rolling material
downslope over trench.
(C) Terminal Ends -utilize one of the methods detailed below for all terminal ends of RECPs
(1) Staples. Install the 1tECPs 3 ft. (900 mm) beyond the end of the channel and secure end with a
single row of stakes/staples on 1 ft. (300-mm) centers. Stakes/staples for securing RECPS to the
soil are typically 6 in. (150 mm) long.
(2) Anchor trench. Excavate a 6 in. by 6 in. (150 mm by 150 mm) anchor french. Extend the
terminal end of the RECPs 3 ft. (900 mm) past the anchor trench. Use stakes or staples to fasten the
product into the bottom of the anchor trench on 1 ft. (300 mm) centers. Backfill the trench and
compact the soil into the anchor trench. Apply seed and any necessary soil amendments to the
compacted soil and cover with remaining 1 ft. (300 mm) terminal end of the RECPs. Secure terminal
end of RECPs with a single row of stakes or staples on 1 fr. (300 mm) centers.
(3) Check slot. Construct astake/staple check slot along the terminal end of the RECPs by installing
two tows of staggered stakes/staples 4 in. (100 mm) apart on 4 in. (100 mm) centers.
Slope Installations. At the top of slope, anchor the RECPs according to one of the method detailed in Section
(A) above. Securely fasten all RECPs to the soil by installing stakes/staples at a minimum rate of 1.3/ydZ
(I.5/mZ) within the body of the blanket. For the most effective RECP installation use stake/staple pattems and
densities as recommended by the manufacturer. For adjacent and consecutive rolls of RECPs follow seaming
instructions detailed in Section (B) above. The terminal end of the RECPs installation must be anchored using
one of [he methods detailed in Section (C) above.
Channel Installations. Construct an anchor trench at the beginning of the channel across its entire width
according to Section (A) (2) above. Follow the manufacturer's installation guidelines in constructing additional
anchor trenches or stake/staple check slots at intervals along the channel reach and at the tetmirtal end of the
channel, according to paragraph (A) above respectively. Unroll RECPs down the center of the channel in the
primary water flow direction. Securely fasten all RECPs to the soil by installing stakes/staples at a minimum
rate of 1.7/yd2 (1.5/m~). Significantly higher anchor rates and longer stakes/staples may be necessary in sandy,
loose, or wet soils and in severe applications. For adjacent and consecutive rolls of RECPs follow seaming
instructions detailed in Section (B) above. All terminal ends of the RECPs must be anchored using one of the
methods detailed in Section (C) above. ,
With any RECP installation, ensure sufficient staples to resist uplift from hydraulics, wind, mowers, and foot
traffic. For the most effective installation of RECPs, the ECTC recommends using stake/staple patterns and
densities as recommended by the manufacturer.
Repair any damaged areas immediately by restoring soil to finished grade, re-applying soil amendments and
seed, and replacing the RECPs.
