The Difference Mirafi
®
N-Series Nonwoven
Geotextiles Make:
• Construction. Mirafi
®
N-Series polypro-
pylene nonwoven geotextiles easily con-
form to the ground or trench surface for
trouble free installation.
• Strength. Mirafi
®
N-Series geotextiles
withstand installation stresses with high
puncture and tear resistance.
• Drainage. High permittivity properties pro-
vide high water flow rates while providing
excellent soil retention.
• Environmental. Mirafi
®
N-Series geotex-
tiles are chemically stable in a wide range
of aggressive environments.
• Cost Effective. Mirafi
®
N-Series geotex-
tiles provide economical solutions to many
civil engineering applications including a
cost effective alternative to graded aggre-
gate filters.
APPLICATIONS
Mirafi
®
N-Series nonwoven geotextiles are
used in a wide variety of applications includ-
ing soil separation and drainage applications.
Lightweight nonwovens are predominantly
used for subsurface drainage applications
along highways, within embankments, under
airfields, and athletic fields. For these drain-
age structures to be effective, they must
have a properly designed protective filter.
Mirafi
®
N-Series nonwoven geotextiles elimi-
nates the challenge of determining the
aggregate gradation required to match soil
conditions, finding a convenient and econom-
ical source of a specific aggregate, transport-
ing and placing graded aggregate, and assur-
ing that the constructed in-place drainage
system provides effective filter performance.
Heavyweight nonwovens are used in critical
subsurface drainage systems, soil separa-
tion, permanent erosion control, and
geomembrane liner protection within land-
fills. These geotextiles provide the required
strength and abrasion resistance to with-
stand installation and application stresses to
create an effective, long term drainage solu-
tion.
INSTALLATION GUIDELINES*
French and Trench Drains Geosynthetic Placement
Cut geosynthetic to proper width prior to
placement. Width should be enough to con-
form to the trench perimeter with at least a
6in (15cm) top overlap. Place the geosynthe-
tic roll over the trench, and unroll enough
geosynthetic that the geosynthetic can be
placed down into the trench. Anchor the
edges of the geosynthetic with heavy objects
to prevent the geosynthetic from falling into
the trench. Where overlaps are necessary
between rolls, allow for 3 ft (1m) overlap
from the upstream to the downstream roll.
* These guidelines serve as a general basis for installation.
