Key Elements for Successful Product Performance (cont.)
Step One: Prepare site by removing
debris and obstructions and minimizing
disturbances to yield a smooth, even
ground surface. If seeding is required,
place seed, as specified, prior to instal-
lation of SRFRs.
Step Two: Determine if an anchor
trench is required. Verify manufactur-
er’s recommendations based on site-
specific characteristics and product
properties. Map out placement of SRFR
to determine location and profile of an-
chor trench.
Step Three: For SRFRs that require an

the soil surface is between 12” - 16”.
Site-specific conditions such as com-
pacted soil or rocky subgrade will dic-
tate what is realistic and practical for
an adequate installation. First, make
pilot hole through the center of the
SRFRs using a straight metal rod (i.e.
rebar), then insert the wooden stakes
(this step may not be necessary if using
porous SRFRs or metal pins.)
SRFRs may be secured by driving stakes
through the body of the unit, or by pen-
etrating the netting of the unit on an
angle. Individual manufacturers provide
product/project specific recommenda-
tions for the staking of SRFRs. For either
staking method, drive the stakes or pins
through the SRFR or the netting only,
leaving no more than 1 to 2 inches of
the stake or pin exposed. Stakes or pins
should be placed according to manufac-
turer’s recommendations. On very steep
or erosive slopes, additional stakes or
pins may be placed on the down-slope
side of the roll. In very compacted soil
shorter stakes or pins may be necessary.
