Key Takeaways
- Read five numbers. Weight, UV rating, tensile strength, flow rate, and apparent opening size tell you whether a fabric will perform.
- Spec by weight, not thickness. Oz/yd² and GSM predict durability; thickness alone does not.
- UV is rated in hours. Sun-exposure ratings, commonly 200 to 1600+ hours, set how long an exposed install lasts.
- Bid work needs standards. AASHTO/NTPEP listings and GSM data make a fabric eligible on spec-driven jobs.
- Compare guaranteed values. Use minimum average roll values (MARV), not best-case numbers, when comparing products.
A landscape fabric spec sheet, not a product photo, tells you whether a roll will survive its warranty on a real site. As a manufacturer and supplier of woven ground cover and geotextile, we help contractors and distributors read those specs and match them to the job. This guide is the technical reference for estimators, site crews, and distributors who buy by specification.
What specs define a landscape fabric?
Five properties carry most of the engineering weight: weight, UV rating, tensile strength, flow rate, and apparent opening size. Together they tell you how durable, how long-lived, how strong, and how permeable a fabric is. A product that lists none of them should be treated as a commodity, not a commercial material.
How do you read a landscape fabric spec sheet?
Work through the numbers in order, because each answers a different question about performance.
Fabric weight (oz/yd² and GSM)
Weight is the fastest proxy for durability. Commercial woven ground cover typically runs from about 3.2 oz/yd² for nursery grade up to 4.75 oz/yd² for heavy hybrid weed barrier. Heavier fabric resists puncture from gravel and equipment, which matters more on a commercial install than on a bed.
UV stabilization
UV rating decides how long the fabric lasts in sunlight, and it’s expressed in hours of sun exposure, commonly 200 to 1600+. For exposed installs such as nursery floors and paths, UV rating is the single most important spec, and covering the fabric extends life further.
Tensile and puncture strength
For stabilization under aggregate, pavers, or traffic, read grab tensile and puncture values. Woven geotextiles deliver high tensile strength with low elongation, which is why they’re specified for separation and stabilization rather than filtration.
Flow rate and apparent opening size
Match flow to the job. Woven ground cover has a deliberately slow flow and behaves like a semi-sealed barrier, while non-woven is high-flow for drainage. For filtration applications, apparent opening size (AOS) must be matched to the soil so the fabric retains fines without clogging.
| Spec | What it tells you | How it’s expressed |
|---|---|---|
| Weight | Durability and puncture resistance | oz/yd² and GSM |
| UV rating | Exposed lifespan | Hours of sun exposure |
| Tensile / puncture | Strength under load | Grab tensile, puncture (N) |
| Flow rate | How fast water passes | Permeability |
| Apparent opening size | Soil retention in filtration | AOS / O95 (mm) |

What roll sizes and formats matter?
Roll width drives labour as much as material. Commercial woven ground cover ships in wide rolls and long lengths, and choosing the widest roll the pad allows cuts seams, pinning, and weed-entry points across a large site. Confirm width availability before pricing, since changing widths mid-job affects both material and labour.
What documentation should a supplier provide?
For bid-eligible and spec-driven work, ask for the paperwork up front. A commercial supplier should provide GSM and weight data, tensile and flow specs, AASHTO/NTPEP listings where applicable, and lot traceability. Documentation is what makes a fabric qualify on spec-driven and public-works projects, and it’s the difference between a supplier and a reseller.
Why contractors and distributors choose Anita Plastics
The right supplier backs every spec with documentation and consistent stock. Contractors and distributors choose Anita Plastics as their woven ground cover and geotextile supplier for:
- NTPEP-listed, spec-ready woven geotextile and erosion-control products.
- Documented weight, UV, and tensile data on request.
- US warehouse stock with blind and drop ship for fast lead times.
- Custom width, weight, and GSM from a backward-integrated factory.
- In-house quality testing and lot traceability.
- Private-label and bulk supply for distributors and resellers.

Frequently Asked Questions
What specifications matter most for landscape fabric?
Weight (oz/yd² and GSM), UV rating, tensile and puncture strength, flow rate, and apparent opening size. Weight predicts durability, UV rating sets exposed lifespan, tensile matters under load, and flow plus AOS govern drainage and filtration performance.
How do you read fabric weight on a spec sheet?
Read oz/yd² or GSM, not thickness. Commercial woven ground cover runs roughly 3.2 oz/yd² for nursery grade up to 4.75 oz/yd² for heavy hybrid weed barrier. Heavier fabric resists puncture from gravel and equipment, which matters most on commercial installs.
What UV rating should commercial landscape fabric have?
UV stabilization is rated in hours of sun exposure, commonly 200 to 1600+. For exposed installs such as nursery floors and paths, choose a higher rating, and cover the fabric with mulch or aggregate to extend its life further. UV rating is the key spec for exposed work.
What is MARV and why does it matter?
MARV is the minimum average roll value, the property a fabric is guaranteed to meet or exceed in most cases. When comparing products, compare MARV to MARV and design to MARV, not to best-case or typical figures, which aren’t guaranteed across the roll.
What documentation should a fabric supplier provide?
GSM and weight data, tensile and flow specs, AASHTO/NTPEP listings where applicable, and lot traceability. Documentation is what makes a fabric bid-eligible on spec-driven and public-works projects, and it separates a commercial supplier from a commodity reseller.
