Dewitt Landscape Fabric
The DeWitt Company has been manufacturing premium-quality landscape fabric for more than 30 years. As pioneers of permeable weed control fabric they were first to market with it, and they now offer one of the widest selections of woven ground covers available. This page covers the seven DeWitt fabrics we stock.
Almost every wrong purchase in this category comes from the same confusion, so it is worth settling before anything else: woven and non-woven fabrics are not interchangeable. They look similar on a product page and they do fundamentally different jobs.
Woven fabric is a surface product. It has high tensile strength, it is built to be walked on, planted through and exposed to sun for years, and it blocks light. That is a weed barrier or a ground cover. Non-woven fabric is a buried product. Water passes readily through the body of the fabric, it separates and filters, and it cushions. That is drainage, wall backfill, liner protection.
Get that split right and the rest is straightforward — weight and roll size follow from the specific job.
The Decision
What Is The Fabric Doing?
Seven fabrics, split by where they sit. Find the job below.
01
Buried — non-woven fabrics
General Weed Control
Sunbelt · woven black · 3.2 oz
The general purpose ground cover. Blocks 99.7% of direct and indirect sunlight while letting water, air and nutrients through, and striped every 12″ for plant spacing.
View Sunbelt → 02
Cost Effective Cover
Ultraweb 3000 · woven black · 2.2 oz
The lighter, more economical woven cover, with the highest UV protection in the range and excellent water infiltration. The real comparison is against black mulching plastic, and it is not close.

Reflective & Frost Protection
White Ground Cover · woven white · 3.2 oz
The only fabric here with two seasonal jobs. White reflects rather than absorbs, and the reflective properties plus the thickness let it double as a frost blanket over plants and shrubs.

Heavy Duty Weed Barrier
Pro 5 & 20 Year · needle-punched · 4.1–5 oz
Two heavyweight barriers for under mulch, rock and soil. Pro 5 at 5 oz adds slope stability and 12″ stripes; the 20 Year at 4.1 oz is rot resistant with a stated two-decade lifespan.

05
Drainage & Separation
Non-Woven Geotextile · 4, 4.5, 8 oz
Staple fibers that will not rot or decay. Separation under aggregate, drainage and filtration, permanent erosion control behind walls, and cushioning for roads, landfills and airfields.
View Non-Woven Geotextile → 06
Wall Backfill & Drain Wraps
Soil Filter Fabric · 3.1 to 6 oz
Holds soil behind retaining walls and keeps drainage pipes from clogging with dirt. Installed correctly it is the difference between a drain that works and one you dig up.
View Soil Filter Fabric → 07
Pond Liner Protection
Pond Underlayment · 4, 6, 8 oz
Goes beneath the waterproof liner, shielding it from rock and ridges and supporting it over soft areas. Replaces the cardboard, sand and old carpet that fail a few seasons in.

| Fabric | Construction | Weight | Position | Job |
|---|---|---|---|---|
| Sunbelt Ground Cover | Woven | 3.2 oz | Surface | General purpose weed control and water conservation |
| Ultraweb 3000 | Woven | 2.2 oz | Surface | Cost effective cover with the highest UV protection |
| White Ground Cover | Woven | 3.2 oz | Surface | Reflective white, and doubles as a frost blanket |
| Pro 5 & 20 Year | Woven, needle-punched | 4.1 & 5 oz | Surface | Heavy-duty weed barrier under mulch, rock and soil |
| Non-Woven Geotextile | Non-woven | 4, 4.5, 8 oz | Buried | Drainage, filtration, separation and cushioning |
| Soil Filter Fabric | Non-woven | 3.1–6 oz | Buried | Behind retaining walls and wrapping drainage pipe |
| Pond Underlayment | Non-woven | 4, 6, 8 oz | Buried | Protecting pond liners from sharp objects |
Weight is not a quality rating. Within a line, heavier means more strength, more
puncture resistance and more cushioning — and it costs more. A 3.1 oz filter fabric is not a
worse product than an 8 oz geotextile; it is a different specification for a lighter job.
The Distinction That Matters
Woven Or Non-Woven?
Woven — surface fabrics
- Blocks light. Weed suppression works by denying light, and woven fabric is built to do it.
- High tensile strength. Resists tearing and puncture when walked on and planted through.
- UV treated for exposure. Designed to sit in direct sun for years without breaking down.
- Lower flow through the fabric. Water passes, but nothing like a non-woven.
Use for weed barrier, ground cover, nursery and greenhouse floors, under mulch and stone.
Non-woven — buried fabrics
- High flow through the body. Water moves through the fabric itself, not just the weave.
- Separates and filters. Keeps aggregate and soil apart while letting water pass.
- Cushions. Protects liners and spreads load over sharp or uneven ground.
- Will not rot. Built to be buried permanently and forgotten.
Use for drainage, wall backfill, pipe wraps, pond liner protection, separation under aggregate.
The quick test. If the fabric will be visible or walked on, you want woven. If it
will be covered by stone, soil or a liner and never seen again, you want non-woven.
Across The Range
What Every DeWitt Fabric Shares
Thirty years of developmentDeWitt pioneered permeable weed control fabric and was the first company to bring it to this market.
Permeable by designEvery fabric here lets water through. What varies is how much, and whether light is blocked as well.
UV treatedThe surface fabrics are treated for prolonged exposure, which is what separates a ground cover from generic sheeting.
Roll widths to match the bedFrom 3′ to 16′ across the range, so you can match roll width to the area and cut seams and offcuts.

Three Rules That Apply To All Of Them
Overlap, never butt
Whether it is a weed barrier or a filter layer, a butted joint that opens is a gap in the fabric's job. Overlap adjacent runs and pin the seam.
Keep cuts as small as possible
Every opening beyond what the plant or pipe needs is somewhere light reaches the soil or fines reach the aggregate. Cut tight.
Pin it properly
Staples or pins along every edge, at every seam, and anywhere the fabric lifts. Fabric that is not in contact with the ground is not doing its job.
DeWitt Landscape Fabric FAQs
What is the difference between woven and non-woven fabric?
Woven fabric is a surface product: high tensile strength, blocks light, built to be walked on, planted through and exposed to sun. Non-woven is a buried product: water passes readily through the body of the fabric, it separates and filters, and it cushions. They are not interchangeable.
Which DeWitt fabric do I need?
Start with where it sits. Surface: Sunbelt for general weed control, Ultraweb 3000 for cost effectiveness, White Ground Cover for reflection and frost protection, Pro 5 or the 20 Year for heavy-duty barrier. Buried: non-woven geotextile for separation and drainage, soil filter fabric for walls and pipe wraps, pond underlayment under a liner.
Does a heavier fabric mean a better fabric?
No. Within a line, heavier means more strength, more puncture resistance and more cushioning, and it costs more. Across lines the weights are not comparable at all — a 3.1 oz filter fabric and an 8 oz geotextile are different specifications for different jobs.
Can I use a weed barrier for drainage, or the other way round?
Not sensibly. A woven weed barrier passes far less water through the fabric body, so as a filter layer it restricts flow. A non-woven geotextile is not built for surface exposure or foot traffic. Using either in the other's place is the most common and most expensive mistake in this category.
Do all of them let water through?
Yes, all are permeable — that is the point of a fabric over plastic sheeting. What varies is how much water passes and whether light is blocked at the same time.
What size roll should I order?
Work out the area in square feet, then match roll width to the shape of what you are covering rather than picking on area alone. Several lines offer two rolls with identical coverage in different widths, and matching width to the bed is what keeps seams and offcuts down.
How do I secure landscape fabric?
Landscape staples, fabric pins, stakes or spikes along every edge, at every seam and anywhere the fabric lifts. On some fabrics rocks and mulch can hold it where pinning is impractical.
Will these fabrics rot?
No. All are polypropylene, which does not rot or decay. The surface fabrics add UV treatment because sunlight rather than moisture is what degrades an exposed fabric.
What does shipping cost?
Nothing. Shipping is free on every order, across all seven fabrics, every weight and every quantity.
Can you help me choose?
Yes. Tell us what the fabric has to do — whether it will be exposed or buried, what is going on top of it, and how heavy the loads or the soil are — and we will tell you which of the seven fits. Call (800) 524-4161, Monday to Friday, 5:00 am to 3:00 pm Pacific.
