What is Geotextile Material?
Geotextile materials are permeable fabrics used in geotechnical and environmental engineering that perform one or more of five core functions:
separation, filtration, drainage, reinforcement, and protection.
They play a vital role in modern civil and environmental infrastructure, used in:
Luxury large-scale landscaping
Landfill base and cap systems
Retaining wall support
Canal and pond lining
Stormwater management
Agricultural field stabilization
Geotextile Liner Types We Offer:
Woven Geotextile Fabric
Engineered for reinforcement and separation, woven geotextiles provide high tensile strength and are ideal for embankments, and load-bearing applications.
Key Features of Woven Geotextile Fabric:
High Strength-to-Weight Ratio
Outperforms nonwoven geotextiles in demanding load-bearing applications.
Durability & Dimensional Stability
Woven construction ensures reliable, long-term performance under stress.
Effective Soil Separation
Prevents mixing of base and subgrade materials.
Erosion Control Performance
Mitigates surface and sub-surface soil loss in embankments, channels, and slopes.
Structural Reinforcement
Increases tensile strength in weak subgrades, embankments, and retaining systems.
Common Applications for Woven Geotextile Fabric:
Retaining walls and slope reinforcement
Landfill base and cap separation
Erosion control for levees, canals, and streambanks
Soft soil improvement and structural pads
Non-Woven Geotextile Fabric
Designed for drainage, filtration, and protection, non-woven geotextiles are needle-punched fabrics that perform well in environmental containment systems and water infrastructure.
Key Features of Nonwoven Geotextile Fabric:
Durable Needle-Punched Construction
Ensures performance under soil loads, traffic pressure, and environmental stress.
Excellent Hydraulic Properties
High permeability and flow-through characteristics make them ideal for filtration and drainage.
Superior Survivability
High elongation properties help withstand installation and operational stresses in transportation and environmental systems.
Versatile Performance
Ideal for applications where separation, filtration, cushioning, and drainage are critical.
Common Applications for Non-Woven Geotextiles:
Drainage layers in roads, highways, and railways
Erosion control on slopes, canals, and embankments
Filtration behind retaining walls and under riprap
Cushion layer for geomembrane protection in landfills
Dewatering bags for sediment control
Concrete breaker fabric in pavement and utility trench separation
Geotextile Material Specifications
Nonwoven Geotextile (Needle-Punched)
| Property | Typical Range |
|---|---|
| Weight | 4 – 16 oz/yd² |
| Thickness | ~70 – 175 mil |
| Grab Tensile Strength | ~200 – 425 lbs |
| Elongation | ~50% |
| CBR Puncture Resistance | ~600 – 1,200 lbs |
| Apparent Opening Size (AOS) | ~0.15 – 0.60 mm |
Higher weights provide greater puncture protection and are typically used as cushion layers beneath geomembrane liners. Lighter weights are used where filtration and drainage are the primary functions. Nonwovens are resistant to UV, rot, chemicals, and biological degradation.
Selection by Application
| Primary Function | Recommended Type |
|---|---|
| Filtration | Nonwoven |
| Drainage | Nonwoven |
| Cushioning / Liner Protection | Nonwoven (Higher Weight) |
| Separation | Woven or Nonwoven |
| Stabilization | Woven |
| Reinforcement | Woven |
For projects that need more than one function, woven and nonwoven geotextiles are often used together in a composite system. Our team will help you specify the right material or combination for your subgrade conditions and load requirements.

Woven Geotextile (Slit-Film & Monofilament)
| Property | Typical Range |
|---|---|
| Strength Grades | W100, W180, W250 (and higher) |
| Grab Tensile Strength | Up to ~315+ lbs |
| Elongation | ~15% |
The "W" grade reflects the geotextile's tensile strength class. Lower elongation (~15% vs. ~50% for nonwoven) makes wovens better suited to structural reinforcement applications where dimensional stability is critical.
Geotextile Roll Sizes & Coverage
| Type | Roll Width | Roll Length | Coverage per Roll |
|---|---|---|---|
| Nonwoven | ~15 ft | ~300 – 700 ft | ~500 – 1,150 yd² |
| Woven | ~12.5 – 17.5 ft | ~300 – 700 ft | Varies by Width |
Woven vs. Nonwoven Geotextiles: What's the Difference?
| Properties | Woven | Nonwoven |
|---|---|---|
| Primary Function | Reinforcement, separation | Filtration, drainage, cushioning |
| Tensile Strength | Higher | Moderate |
| Elongation | Low (~15%) | High (~50%) |
| Permeability / Flow | Lower | Higher |
| Best For | Structural / load-bearing | Hydraulic / protection |
Our geosynthetic liner company offers both woven and nonwoven geotextiles to best meet the needs of your project. Many projects use both in a composite system. For example, a nonwoven cushion directly above and below a geomembrane, with a woven reinforcement layer in the road base or cap. We design and install multi-layer systems regularly.

Frequently Asked Questions (FAQs) About Geotextile Material:
-
For projects requiring both functions, the primary need dictates your choice. Woven geotextiles provide excellent stabilization but are less effective for cross-plane drainage. Non-woven geotextiles offer superior filtration and drainage but have lower load-bearing capacity. In complex cases, they can be used together in a composite system—using the non-woven for drainage/filtration and the woven for reinforcement. Our experts can help you design the most effective solution.
-
The choice depends on the subgrade condition and project goals.
Use a woven geotextile when building over soft, unstable soil. Its high tensile strength acts as a reinforcement layer, creating a stable platform and preventing the road base from sinking.
A non-woven geotextile is typically used on stable subgrades where the primary needs are separation (preventing the mixing of subsoil and gravel) and subsurface drainage to extend the road's lifespan.
-
Yes, in complex projects, they are often used together to perform different functions. A common example is in a landfill: a non-woven geotextile is used as a cushioning layer directly above and below the geomembrane liner to protect it from punctures. Then, a woven geotextile might be used in the drainage layers or cap system for its superior tensile strength and reinforcement properties. Our experts can help you design a multi-layer system that leverages the strengths of both material types.
The key factors that influence their lifespan include:
Material Type
UV Exposure:
Chemical Exposure
Installation Quality
Physical Protection
-
Cushion layer weight depends on subgrade conditions and the liner being protected. Our nonwoven geotextiles range from 4 to 16 oz/yd², with higher weights specified for rocky subgrades, textured liners, or high-stress applications. We commonly install nonwoven cushion layers above and below HDPE and LLDPE geomembranes as part of our standard containment system installations.
-
The W rating (W100, W180, W250, etc.) is a strength-class designation for woven geotextiles, with higher numbers indicating greater tensile capacity. Higher W ratings are specified for heavier load conditions, weaker subgrades, and longer service life requirements.
