TECHDRAIN DRAINAGE COMPOSITE
TechDrains are
prefabricated
subsurface
drainage products
that directly
replace the
granular drainage
layer completely or
partially. These are
used for reinforced
soil wall retaining
structures. TechDrain Drainage Composites
provide mediums for guiding groundwater
and seepage water to drainage pipes/weep
holes, and they reduce the pore pressures on
the wall. It prevents the intermixing of the
backfill soil with filter media, thus avoiding the
clogging of the filter media. The main objective
of TechDrain material is to combine the best
features of different materials in such a way
that specific problems related to drainage,
filtration and separation are solved in optimal
performance and minimum cost. TechDrains are
convenient to place.

TECHGRID PP BIAXIAL GEOGRID
TechGrid PP
is a family of
integrally formed
biaxial geogrids
manufactured from
superior grades
of polypropylene
using precisely
controlled
punching and
drawing processes.
TechGrid develops tensile forces that maintain
high stiffness in the granular material by
effectively controlling cyclic load-induced
lateral deforms. TechGrid acts as a stretched
membrane that resists the vertical loads while
simultaneously providing confinement to the
subgrade soil. TechGrid functions as a separator
that preserves the designed thickness and
integrity of granular layers placed over weak
soil. It enhances the structural performance
of granular subbase and base courses in
unpaved roads as well as in flexible pavements
for roadways and airfields. It improves the
performance of ballast and sub-ballast layers
of railway track beds, prevents surface slope
failure when used as secondary reinforcement,
and improves the performance of load transfer
platforms over pie embankments.

TFI 3000 SERIES HIGH-STRENGTH
POLYESTER WOVEN GEOTEXTILE
TFI 3000 Series
High-Strength
Polyester Woven
Geotextiles
are woven
multifilament
geotextiles
manufactured
from high tenacity
polyester filament
yarns. These
have high tensile strengths, low elongation,
low creep and excellent durability and
are recommended for applications where
the predominant geosynthetic function is
reinforcement. With its low apparent opening
size and adequate permeability, the geotextile
can also perform the function of separation.
TFI 3000 Series High-Strength Polyester Woven
Geotextile is used for subgrade separations
and stabilization for roads, airports, rail tracks,
area stabilization, ground improvement, load
transfer platforms, basal reinforcement of
embankments and geotextile tubes.

TENAX TT SERIES UNIAXIAL GEOGRIDS
Tenax TT Series
Uniaxial Geogrids
are for reinforcing
soil retaining walls,
slopes, landslide
repair applications,
embankment
stabilization,
temporary walls
and veneer
stability in landfill
applications. The Tenax TT Series Uniaxial
Geogrids are being produced in the company's
Maryland plant using select grades of highdensity polyethylene (HDPE) resins that resist
elongation (creep) when subjected to high
loads for long periods of time, as required
in slopes and walls. This unique process of
extrusion to punched and drawn to monoorientation enhances tensile properties. This
new production capability allows Tenax to
produce the only HDPE geogrid in a width of 6.5
feet; the additional width speeds construction
and reduces overall waste.

3D-T SERIES TRIPLANAR GEOGRIDS
3D-T Series
Triplaner
Geogrids work
well for ground
stabilization
and subbase
reinforcement
for permanent,
unpaved and
temporary access
roads; working
platforms; and levee construction. Tenax
3D Grids are manufactured from a unique
extrusion technique resulting in a perforated
polypropylene sheet that is specifically shaped
to create a triplanar reinforcing structure. This
unique extrusion process produces a large,
concave-shaped rib to better trap aggregate
materials by restricting the horizontal
movement of stone particles and preventing
displacement. Higher profile ribs and junctions
improve interlock and stress distribution,
reducing rutting and aggregate base thickness.

TENAX TRIPLANAR SERIES GEONETS
AND GEOCOMPOSITES
Tenax Triplanar
Series Geonets and
Geocomposites are
primarily used as
drainage in landfill
applications.
Tenax Tendrain
and Tendrain
II are typically
used in leachate
collection in landfill
liners and leak detection. Tenax Tenflow is
typically used for landfill capping, surface water
collection and removal system, and landfill gas
venting. Tenax is once again manufacturing
its Triplanar geonet structures in its Baltimore,
Md., facility. Tenax Triplanar Series Geonets are
high-performance HDPE drainage structures
consisting of thick supporting ribs with
diagonally placed top and bottom ribs. The
three sets of intersecting strands form unique
flow conduits that provide extremely high
flow capacity, high compressive resistance and
enhanced tensile properties.
