Woven Geotextile

SIGMA woven geotextile is a high-strength geotextile fabric made by weaving high-tenacity polypropylene (PP) and polyester (PET) yarns — monofilament, fibrillated or slit-film — into a dimensionally stable sheet. Built to the AASHTO M288 standard and classified by installation survivability (Class 1–3), this woven geotextile membrane delivers high grab, tear and CBR puncture strength for separation, stabilization and reinforcement under roads, driveways, car parks and embankments. Supplied as a black woven geotextile in stock weights and roll sizes, shipped direct from our factory.

High-strength woven geotextile to AASHTO M288

SIGMA woven geotextile fabric is manufactured by weaving high-tenacity polypropylene and polyester yarns — monofilament, fibrillated yarn or slit-film — into a strong, dimensionally stable sheet. The woven geotextile membrane is built to the AASHTO M288 standard, which grades a geotextile cloth by installation survivability: Class 1 for the most severe sites, Class 2 as the default, and Class 3 for the least severe. Because the woven fabric has low elongation (under 50%), it spreads load and keeps its strength under heavy traffic — exactly what a road or driveway base needs.

Separation, stabilization and reinforcement

As a separation and stabilization geotextile, this woven geo fabric keeps aggregate from punching down into soft subgrade and stops fines from pumping up, so a thinner, longer-lasting base course can be built. It is the workhorse woven driveway fabric and woven stabilization fabric for unpaved roads, car parks and working platforms, and provides reinforcement under embankments and railway subgrade. High grab, trapezoid tear and CBR puncture strength let the high-strength woven geotextile survive rough placement over stone and irregular ground.

How a woven geotextile is made

A woven geotextile fabric is built the traditional way — by weaving individual high-tenacity threads into sizeable sheets on a loom. Those threads can be fibrillated yarns, monofilaments or slit film, and the weave pattern and yarn type set the balance between tensile strength, opening size and water flow. A woven monofilament geotextile uses round filaments for a more open, permeable structure, while a slit-film weave is tighter and stronger in tension. The result is a dimensionally stable geotextile membrane that keeps high tensile strength under both dry and wet conditions, resists corrosion, acid and alkali, and will not rot or mildew.

Choosing a class and weight

AASHTO M288 specifies a woven geotextile by survivability Class (1, 2 or 3) rather than by weight, and commercial grades from roughly 120 gsm to 300 gsm map onto those classes. Buyers often shop by weight too — 4 oz, 6 oz and 8 oz geotextile fabric are common, and gsm and oz both describe mass per unit area. Tell us the application, subgrade CBR and aggregate, and we will recommend the right woven geotextile fabric for a driveway, road or reinforcement job. Where filtration is the priority — for example around a French drain — a needle-punched nonwoven geotextile is usually the better choice, since woven slit-film geotextiles are not permitted for subsurface drainage.

Installation and overlap

Lay the woven geotextile fabric directly on a graded subgrade with the roll running in the direction of traffic, then place and compact aggregate on top — never drive plant directly on the bare geotextile cloth. Overlap adjacent rolls by roughly 300–600 mm on firm ground and more on soft or wet subgrades; where loads are high or the seam must carry tension, sew the panels (sewn seam strength must be at least 90% of grab strength). Because the woven geo fabric has low elongation it does the load-spreading work as soon as the first lift is compacted, which is why it is the standard woven stabilization fabric and woven road fabric for haul roads and working platforms.

Quality and supply

As the geotextile manufacturer we control yarn selection, weaving and finishing, so every batch of black woven geotextile is UV-stabilized and tested to AASHTO M288 minimum average roll values. We supply stock weights and roll sizes and can match the performance of common reference grades buyers ask for, then ship direct from our factory. For a woven geotextile price, send us the class or gsm, total area in square metres and destination port and we will quote ex-works the same business day.

Frequently asked questions

What standard is your woven geotextile made to?

Our woven geotextile fabric is manufactured to AASHTO M288, the standard specification for geosynthetics. AASHTO M288 grades a geotextile by installation survivability — Class 1 (most severe), Class 2 (default) and Class 3 (least severe) — with minimum average roll values for grab, sewn seam, trapezoid tear and CBR puncture strength as shown in the table above.

How do I choose between Class 1, 2 and 3 and the right weight?

Class 2 is the default when no site-specific data is given; step up to Class 1 for severe placement over coarse, angular stone or soft subgrade, and down to Class 3 only for mild conditions. Commercial weights from about 120 gsm to 300 gsm map onto these classes. Send us the subgrade CBR, aggregate and traffic and we will recommend a class and weight.

What is woven geotextile used for?

It is a separation, stabilization and reinforcement geotextile — used as a woven driveway fabric under gravel driveways, beneath unpaved roads, car parks and working platforms, in embankment and railway subgrade reinforcement, and as permanent erosion control under riprap. For filtration around drains, choose a nonwoven geotextile instead.

Can woven geotextile be used for a French drain or filtration?

Generally no. Woven slit-film geotextiles are not permitted for subsurface drainage (filtration) under AASHTO M288 because their open area and permittivity are low. For a French drain or filter application use our needle-punched nonwoven geotextile, which is sized by permittivity and apparent opening size to the soil gradation.

How much does woven geotextile cost?

Woven geotextile price depends mainly on the survivability class / weight, roll width and order volume. As a manufacturer we quote ex-works per square metre or per roll; send us the class or gsm, total area and destination port and we will return a woven geotextile price the same business day.

What is the difference between monofilament and slit-film woven geotextile?

A woven monofilament geotextile is woven from round filaments, giving a more open, permeable cloth with better water flow; a slit-film woven geotextile uses flat tape yarns for a tighter, higher-tension fabric used mainly for separation and reinforcement. Both are made to AASHTO M288, but note that woven slit-film geotextiles are not permitted for subsurface drainage. Tell us whether you need filtration or load-spreading and we will recommend the right weave.

How do gsm and oz relate, and what weights do you stock?

Both gsm (grams per square metre) and oz (ounces per square yard) describe the fabric mass per unit area — buyers often ask for 4 oz, 6 oz or 8 oz geotextile fabric, while engineers usually specify gsm. AASHTO M288 actually governs by survivability class rather than by mass, so we map a requested weight (roughly 120–300 gsm for woven grades) to the matching class. Send the weight you have in mind and the application and we will confirm an equivalent class and stock grade.

What roll sizes, minimum order and lead time can you offer?

Roll width and length are order-specific and are not governed by AASHTO M288 — contact us for current stock sizes. As the manufacturer we ship full containers worldwide and can advise minimum order quantity and lead time once we know the class or gsm, total square metres and destination port. Quotes are returned the same business day.
