- 1. Prepare soil before installing blankets, including any necessary application of lime, fertilizer, and seed.
- 2. Begin at the top of the slope by anchoring the blanket in a 6" (15cm) deep x 6" (15cm) wide trench with approximately 12" (30cm) of blanket extended beyond the up-slope portion of the trench. Anchor the blanket with a row of staples/stakes approximately 12" (30cm) apart in the bottom of the trench. Backfill and compact the trench after stapling. Apply seed to compacted soil and fold remaining 12" (30cm) portion of blanket back over seed and compacted soil. Secure blanket over compacted soil with a row of staples/stakes spaced approximately 12" (30cm) apart across the width of the blanket.
- 3. Roll center blanket in direction of water flow on bottom of channel. Blankets will unroll with appropriate side against soil surface. All blankets must be securely fastened to soil surface by placing staples/stakes in appropriate locations as shown in the staple pattern guide. When using the Dot System™, staples/stakes should be placed through each of the colored dots corresponding to the appropriate staple pattern.
- 4. Place blankets end over end (shingle style) with a 4"–6" (10cm–15cm) overlap. Use a double row of staples staggered 4" (10cm) apart and 4" (10cm) on center to secure blankets.
- 5. Full length edge of blankets at top of side slopes must be anchored with a row of staples/stakes approximately 12" (30cm) apart in a 6" (15cm) deep x 6" (15cm) wide trench. Backfill and compact the trench after stapling.
- 6. Adjacent blankets must be overlapped approximately 2"–5" (5cm–12.5cm) (depending on blanket type) and stapled.
- 7. In high flow channel applications, a staple check slot is recommended at 30 to 40 foot (9m–12m) intervals. Use a double row of staples staggered 4" (10cm) apart and 4" (10cm) on center over entire width of channel.
- 8. The terminal end of the blankets must be anchored with a row of staples/stakes approximately 12" (30cm) apart in a 6" (15cm) deep x 6" (15cm) wide trench. Backfill and compact the trench after stapling.
