Matching the right fabric to a specific application
is paramount for the success of any project. In partnership
with Propex Fabrics, Hancor provides the widest variety
of woven and nonwoven geotextiles in the industry to meet
drainage, separation, stabilization and soil reinforcement
needs.
Nonwoven Fabrics (Needle Punched)
These fabrics are designed to filter soil particles from
drainage systems and stabilize roadways to increase performance
life. Nonwoven fabrics are made by extruding continuous
filaments of polypropylene which are then cut, opened,
laid into a web, needle-punched, heat-set and rolled into
the finished product.
Nonwoven geotextiles are approved by many local, state
and federal agencies including the Federal Highway Administration,
U.S. Army Corps of Engineers, the Environmental Protection
Agency and AASHTO. Nonwovens are ideal for a variety of
civil engineering applications including:
- Subsurface Drainage
- Roadway Separation
- Railroad Stabilization
- Hard Armor Underlayment
- Landfill Leachate Collection
- Underground Detention/Retention Systems

Nonwoven Fabrics (Spunbonded)
Typar® geosynthetic fabric is made from a continuous polypropylene
filament spun uniformly over a flat surface to make a flat, mat-like fiber.
The crossed filaments are then thermally bonded together, rather than woven,
into a tear-resistant material creating a filtration media that offers
excellent uniformity, puncture resistance and filtration efficiencies.
Woven Fabrics
These fabrics are manufactured from extruded polypropylene monofilaments
interlaced to form a dimensionally stable construction fabric. This process
produces a premium filter that is extremely resistant to soil and biological
clogging. A full range of high quality filtration fabrics has been created
to offer designers several choices for percent open area (POA), the single
most important property in the selection of a woven geotextile filter.
These types of geotextiles are used primarily for:
- Hard Armor Underlayment
- Subsurface Drainage
- Landfill Leachate Collection
Woven Slit Tape Geotextiles
These unique fabrics are made by extruding and slitting
a polypropylene film, then incorporating an ISO-9002 certified manufacturing
process that weaves individual flat yarns into geotextiles featuring high tensile strengths
at low elongation (high tensile modulus). These characteristics allow the
geotextiles to distribute loads, reduce rutting and extend the life of
roads or provide substantial sediment barriers. These types of geotextiles
are used primarily for:
- Unpaved Roadways
- Paved Roadways
- Sediment Control
