INSTALLATION
DETAIL
1. Dig a 150mm by 150mm trench both up-slope, down-slope, and along the top side of the
channel. Prepare the slope soil surface (raking, seeding and fertilising). Note, if used with
stormwater discharge, place the up-slope trench at the face of the discharge structure footer.
2. Begin by placing the centre blanket a minimum of 300mm down-slope of the up-slope trench.
Secure the blanket at the bottom of the trench with staples placed 300mm apart. Backfill and
compact the trench. Apply seed, and fold the blanket over the soil, secure with a row of staples
placed 300mm apart across the width of the blanket (See Diagram A).
3. Roll the blanket vertically down the slope. Secure using the appropriate staple pattern below,
specified by slope. (See staple patterns).
4. Continue placing blankets up the slopes on both sides, with a minimum 100mm overlapping
(Diagram B), and securing each blanket in the beginning trench (Diagram A).
5. Additional horizontal blankets can be joined using a minimum 100mm overlapping or shingle
style in the direction of water flow. Connect the blankets by placing staples approximately
100mm apart across the width of the blankets (Diagram C).
6. For maximum performance a check slot should be placed at 8m-12m intervals. Place a row of
staples 100mm apart along the entire width of the channel. A second row should be placed
below in a staggered pattern (Diagram D).
7. The end of the blanket must be secured in a 150mm by 150mm trench by a row of staples placed
at 300mm intervals (Diagram E).
8. At the top edge of the side slope, fasten the blanket in a 150mm by 150mm trench with staples
placed at 300mm intervals. Install an additional row of staples 300mm down slope of the trench
along the width of the fabric (Diagram F).

When hydroseed hydrosoil is to be used, we recommend to apply
this directly into the growing media first, then apply the T-Recs.
