What is it?A flexible cement-impregnated fabric that hardens when hydrated to form a thin, durable concrete layer.
Concrete Cloth consists of:
• Dry concrete mix
• Reinforcing fiber matrix
• Fabric top surface
• PVC bottom coating
What is Concrete Cloth GCCM?
Fabric top surface
Waterproof PVC coating

Concrete Cloth is a Simple-to-Use Geocomposite Protection Material
• Install like a geotextile
• Hydrate using water
• Cures into a hard, fiber-reinforced concrete layer within 24 hours
Concrete Cloth can be used:
• Where a durable hard armor protective surface is required.
• Where conventional concrete or riprap is difficult or impossible to install.
• Where efficient use of labor and time is desired

Concrete Cloth Case Study: Greenville, AL
Project Details:
Customer: Greenville Alabama
Issue: • Two 72 inch diameter corrugated metal
(CMP) culverts in Greenville, AL, had sections at the invert that had rusted through.
Installation dimensions: • 60 feet long
Alternate Options: • Dig and replace was not an option• The city did not have the money for a full
