for adjacent units. A one foot overlap,
directed up-gradient, is recommended
for most products; however, abutting
and securing with a common stake is
recommended for some of the more po-
rous SRFRs. Figure 5 shows detail for
these methodologies.
Step Nine: For trenched SRFRs, place
soil on up-slope side of the roll and
compact well. The compacted up-slope
soil is placed to act as a sealant of the
SRFR-soil interface in order to prevent
erosion from starting under the SRFR
and to prevent undermining the SRFR.
See Figure 6 for Entrenchment Detail.
Step Ten: For slope applications, the
terminal ends of the SRFRs should be
turned 45 degrees upslope and secured
by stakes to prevent water flow around
the terminal ends of the SRFRs. See
Figure 2 for Terminal End Detail.
dicular to a horizontal ground plane (see
Figure 3, “Entrenchment and Staking
Detail”). Driving stakes perpendicular to
a sloped ground surface may compro-
mise the stability of the SRFR.
An optional method of securing the SRFR
is to drive stakes on both sides of the
SRFR and lace rope between the stakes
securing the SRFR. After the rope is
laced around the stakes, the stakes are
then driven into the slope so that the
rope will hold the fiber roll tightly to
the slope. If metal stakes are used the
rope may be laced and knotted at the
bend at the top of the metal stakes.
See Figure 4 for Schematics of Stake
Lacing.
Step Seven: Secure ends of each SRFR
by staking as described in Step Six.
Step Eight: See manufacturer’s recom-
mendations regarding joining methods
