filtering non-woven geotextiles that may also be working as
separation of protecting layers. The drainage three-dimen-
sional core will have a “W” configuration as longitudinal
parallel channels. Macdrain W 1051 has a flux perpen-
dicular to the plane value of 100 gpm/sf or 100 l/sm. The
drainage core (GMA) is a three-dimensional geomat made
by extruded monofilaments set in the longitudinal parallel
channel configuration.
SELECTION OF FRONT FACE FASCIA
To satisfy the low-carbon policy and green solution capable
of providing a front face surface suitable for vegetation, a
Maccaferri Green Terramesh slope reinforcement system
was selected. A Green Terramesh is a HITEC evaluated
reinforced soil slope system comprised of continuous dou-
ble twisted wire mesh that form the top wrap, facing and
continues in the reinforced soil zone as a reinforcement. The
units are lined with a geosynthetic or biodegradable erosion
control blanke and stiffened with welded mesh panel. Two
triangular brackets and foru steel support struts are used to
achieve the inclination. The soft or medium temper steel
wire is coated with a high abrasion resistant polymer coat-
ing (PoliMac) that provides additional protection for use in
polluted, contaminated or aggressive environments.
A Separation non-woven polypropylene geotextile was
needed to separate the fines of the backfill to the Green
Terramesh units. MacTex N47.1 was selected.
A mix of Southeastern Arizona Native Grass and Forb
Revegetation seed were utilized to perform a hydroseeding
of the fascia of the walls.
