Soil Separation Fabric | Non-Woven Geotextile Filter Fabric (8 oz) - USA Made

Heavy Duty Soil Separation & Drainage Fabric

Sandbaggy 8 oz Non Woven Geotextile Fabric is a commercial-grade soil separation fabric designed to prevent soil and aggregate from mixing. Installed between subgrade soil and gravel or stone, this fabric helps maintain a stable base layer while reducing rutting, contamination, and surface failure.

Use it under gravel driveways, roads, parking areas, pavers, retaining walls, and landscaping projects where keeping materials separated is critical for long-term performance.

Made in the USA from heavy duty needle-punched polypropylene, this 8 oz fabric is built for demanding residential, commercial, and construction applications. It also meets recognized industry standards, including NTPEP compliant, meets AASHTO standards, and DOT compliant specifications.

Features

• PREVENTS MATERIAL MIXING – Keeps soil and aggregate separated to maintain base integrity and reduce contamination.
• MAINTAINS GRAVEL THICKNESS – Helps prevent gravel from sinking into soft soil, reducing the need for frequent regrading or additional material.
• HEAVY DUTY 8 OZ FABRIC – Thick non woven construction built for demanding applications where durability matters.
• ALLOWS WATER TO PASS THROUGH – Permeable design allows water to drain through while keeping soil particles in place.
• MADE IN THE USA – Manufactured domestically with quality materials for reliable performance.
• LONG SERVICE LIFE – Designed to last 50+ years when buried and protected from UV exposure.
• FLEXIBLE & EASY TO INSTALL – Conforms to uneven surfaces and subgrades for easier installation.

Best Applications

• Gravel Driveways
• Private Roads & Access Roads
• Parking Areas
• Under Pavers
• Retaining Walls
• Landscaping & Garden Beds
• Rock & Mulch Underlayment
• Construction Entrances
• Equipment Pads
• Rip Rap Underlayment
• French drains

Why Soil Separation Matters

When gravel or stone is placed directly on soil, the two materials can mix over time. This leads to loss of base thickness, poor drainage, and surface instability.

Sandbaggy non woven geotextile fabric acts as a separation layer or soil barrier that keeps materials in place while still allowing water to pass through. This helps maintain structure, reduce maintenance, and extend the life of your project.

FAQ

What is soil separation fabric used for?

It is used to keep soil and aggregate layers from mixing, helping maintain structure and performance in driveways, roads, and landscaping projects.

Can I use this under a gravel driveway?

Yes. It is commonly used under gravel driveways to prevent the gravel from sinking into the soil below.

Does this fabric allow for water to pass through?

Yes. This non woven fabric is permeable, allowing water to drain while preventing soil migration. 

Can I use this fabric for a French drain?

Yes. This non woven geotextile fabric is commonly used in French drain systems to wrap around gravel and pipe. It helps prevent soil from entering and clogging the system while still allowing water to pass through for proper drainage.

How long does it last?

When buried and protected from UV exposure, it is designed to last 50+ years under proper conditions.

Is this the same as landscape fabric?

This is a heavy duty commercial-grade geotextile, which is significantly thicker and stronger than standard consumer landscape fabrics.
