Find Your Woven Fabric
Three woven constructions — pick the one your job calls for
Woven geotextiles get their strength from how the fibers are interlaced. The construction determines whether a fabric is built for raw tensile strength, water flow, or a balance of both. Here's how the Geotex woven line breaks down.
Stabilization (ST)
200ST · 250ST · 315ST · 350ST
Woven slit-film fabrics built for maximum tensile strength. The workhorse choice for stabilizing soft subgrades and distributing heavy loads.
Best for: haul roads, parking lots, building pads, laydown yards over soft soil.
Monofilament (F)
102F · 104F · 111F · 117F
Woven monofilament fabrics with high flow-through and open area. Engineered for filtration and drainage where water must pass freely while soil is retained.
Best for: subsurface drainage, shoreline and hard-armor underlayment, filtration.
Multifilament (HF / UF)
2x2 · 3x3 · 4x4 (HF & UF)
High-tenacity woven multifilament fabrics that combine strong tensile performance with good hydraulic flow — a balance of stabilization and filtration in one fabric.
Best for: reinforcement plus drainage, demanding separation, soft-soil construction.

When to choose woven over nonwoven
Both fabric families separate and protect, but they solve different problems. Woven fabrics are about strength; nonwovens are about flow. Here's the quick comparison.
You're here
Woven
Made by interlacing flat or round yarns on a loom, giving high tensile strength and low elongation. Built to carry and spread load.
- High tensile strength for stabilization & reinforcement
- Excellent for separation under aggregate
- Lower water flow (except monofilament grades)
Alternative
Nonwoven
Made from needle-punched staple fibers into a felt-like mat, giving high permeability and elongation. Built to filter and drain.
- Excellent filtration & drainage flow
- Great cushion protection for liners & pipe
- Lower tensile strength than woven
Reading the Specs
What the numbers on a woven fabric mean
Geotex woven grades are specified by a handful of key properties. These are the ones that decide whether a fabric fits your project.
Grab & Tensile Strength
The load a fabric carries before failing (lbs). Higher ST numbers mean more reinforcement for soft subgrades.
Flow Rate & Permittivity
How fast water passes through (gpm/ft²). Critical for monofilament filtration and drainage applications.
AOS (Apparent Opening Size)
The effective pore size that controls which soil particles are retained while water still flows.
Where Woven Works
Common applications
Road & haul-road stabilization
ST grades reduce aggregate use and extend service life over soft subgrade.
Parking lots & building pads
Separation and load distribution under paved and unpaved surfaces.
Shoreline & hard-armor underlayment
Monofilament grades filter beneath riprap and erosion-control structures.
Subsurface drainage & separation
Keeps fines out of drainage aggregate while maintaining flow.
Questions
Woven geotextile FAQ
Which Geotex ST grade do I need?
It depends on subgrade strength and load. As a rule of thumb, the softer the soil and heavier the traffic, the higher the ST number you want (200ST → 350ST). For project-specific sizing, call our team at (800) 583-4891 with your CBR and loading.
What's the difference between slit-film and monofilament?
Slit-film (ST) fabrics are woven from flat tapes for maximum strength but low flow — ideal for stabilization. Monofilament (F) fabrics are woven from round filaments with more open area for high water flow — ideal for filtration and drainage.
Do these meet DOT specifications?
Geotex woven grades meet AASHTO/NTPEP standards and many state DOT specs. Check the product spec sheet for the grade you need, or contact us to confirm a specific DOT requirement.
How does shipping work?
All items ship free via standard ground and typically ship within 1–2 business days when ordered before 12:00 noon EST.
