*Mats should be applied with soil fill technique:
**Grade the swale and smooth the top soil, removing any debris and large rocks,
**Seed with turf grass mixture,
**Dig 150 mm anchor trench at the top of the channel,
**Secure blanket into the trench with staples every 300 mm. Backfill and compact soil into the trench. ,**Unroll mat in the direction of flow. Staple as recommended by manufacturer. , **Overlaps should be 150 mm and stapled. Upstream mat should always overlay the downstream mat. ,
**Anchor the bottom end of the channel in a similar fashion to the top,
**Apply 15-20 mm of topsoil over the TRM, without the use of heavy machinery which can tear the mat and/or compact the soil. , **An [[Erosion control blankets|ECB]] may be applied to protect the surface through the first one or two years. ,
**Irrigate until turf grass is established.
