Instructions / Assembly

Lay the SRFRs onto an RECP, the pre-
pared subgrade, or into the trenches in
the soil; ensuring no gaps exist between
the roll and the subgrade or RECP. When
using HECPs, apply them after the SRFRs
have been properly installed.
Wooden stakes or metal pins may be
used to secure the SRFRs. If using wood-
en stakes the minimum dimensions of the
stake should be ¾” x ¾” and long enough
to provide anchoring and stability for the
SRFR. Typically, the stake length below
Always consult with the manufacturer for
specific product installation require-
ments and site specific recommenda-
tions.
It is critical that the SRFRs are installed
perpendicular to the expected water
flow (parallel to the slope contour or
across the width of the channel/swale).
Start the installation from lower eleva-
tion contours proceeding to contours
with higher elevations.
