Rip Rap Fabric | Non-Woven Geotextile Filter Fabric (8 oz) - USA Made

Heavy Duty Rip Rap Fabric for Erosion Control & Underlayment

Sandbaggy 8 oz Non Woven Geotextile Fabric is a commercial-grade rip rap underlayment fabric designed for erosion control, shoreline protection, drainage channels, slopes, and other rock protection projects where filtration and soil separation matter.

Installed beneath rip rap stone, this fabric helps create a stable separation layer between soil and rock. Its permeable, needle-punched design allows water to pass through while helping reduce soil migration and washout beneath the stone.

Made in the USA and built for demanding buried applications, this heavy duty geotextile is ideal for contractors, property owners, municipalities, and erosion control projects that require long-term performance.

Why Use Geotextile Fabric Under Rip Rap?

Rip rap stone helps protect slopes, shorelines, channels, and drainage areas from erosion. But without a proper fabric layer underneath, water can carry fine soil particles through the rock over time.

That soil loss can create voids beneath the rip rap, which may lead to settling, shifting, and reduced erosion protection.

Sandbaggy 8 oz Non Woven Geotextile Fabric helps by:

• Separating soil from rip rap stone
• Helping reduce soil migration and washout
• Allowing water to drain through the fabric
• Supporting long-term stability of the rip rap layer
• Conforming to uneven slopes and channels

Great For Rip Rap Applications

• Shoreline and waterfront protection
• Drainage ditches and swales
• Culvert inlets and outlets
• Creek beds and drainage channels
• Slope stabilization
• Embankment protection
• Stormwater management systems
• Erosion control projects

Built for Long-Term Buried Applications

This commercial-grade fabric is designed for long-term performance when buried beneath rip rap, stone, gravel, or aggregate. When properly installed and protected from constant UV exposure, it can last 50+ years.

Actual lifespan depends on site conditions, installation method, soil conditions, water flow, and UV exposure.

Installation Tips for Rip Rap Projects

• Grade and compact the subgrade before installing fabric
• Lay fabric directly over the prepared soil surface
• Overlap seams by 12–18 inches, or as required by project specs
• Secure fabric with staples, pins, or stakes to prevent shifting
• Place rip rap carefully to avoid tearing or puncturing the fabric
• Cover fabric completely with stone to protect it from UV exposure

FAQ

What does geotextile fabric do under rip rap?

Geotextile fabric acts as a separation and filtration layer beneath rip rap. It helps keep soil from washing out through the rock while still allowing water to drain through.

Is non woven geotextile good for rip rap?

Yes. Non woven geotextile is commonly used under rip rap because it provides filtration, drainage, and separation. Its felt-like construction also helps it conform to uneven ground, slopes, and drainage channels.

What does 80 sieve mean?

80 sieve refers to the fabric’s Apparent Opening Size, or AOS. In simple terms, it means the fabric openings are small enough to help retain fine soil particles while still allowing water to pass through.

Does this fabric meet DOT requirements?

This fabric is NTPEP compliant and meets AASHTO and DOT specifications for many non woven geotextile applications. Always confirm your project’s required specification before ordering.

How long does this fabric last under rip rap?

When properly buried and protected from constant UV exposure, this fabric is designed for long-term use and can last 50+ years depending on site conditions and installation.
