Turf reinforcement mats (TRM) may be required in [[swales ]] which are designed to convey higher velocity events. Most TRM are made of synthetic fibres and intended as a permanent part of the construction (unlike a temporary [[Erosion control blankets| erosion control blanket]]).
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,
#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| erosion control blanket]] may be applied to protect the surface through the first one or two years,
#Irrigate until [[turf|turf grass]] is established.
