Quilted composite geobag combines twill fabric and nonwoven layers for ecological slope protection, wetland restoration and riverbank reinforcement. Learn specs, applications and QC standards.
What Is a Quilted Composite Geobag?
A quilted composite geobag is an innovative geosynthetic product designed for ecological slope protection, wetland restoration and riverbank reinforcement. Unlike traditional PP woven geobags, the quilted composite geobag features a dual-layer structure: an outer layer of 200g green nonwoven fabric for water permeability and vegetation support, and an inner layer of 400g twill woven fabric for structural strength and load-bearing capacity.
The two layers are permanently bonded through a quilting process, preventing layer separation during filling and installation. This unique design combines the ecological benefits of nonwoven fabric with the mechanical strength of woven material, making it ideal for green infrastructure projects across Southeast Asia, Africa and the Middle East.

Manufacturing Process
- Material Laying: 4.2m twill fabric placed on 4.5m nonwoven fabric
- Edge Folding: Both sides folded inward 15cm for clean edges
- Quilting: Quilting machine bonds the two layers permanently
- Cutting: Cut into 1.45m x 4.2m individual units
- Sewing: Fold in half, sew three sides with double needle, leave one side open for filling
- Packing: Palletized, labeled and stacked by zone
Key Advantages Over Standard Geobags
- Better Water Permeability: The nonwoven outer layer allows water to pass through while retaining soil particles
- Ecological Appearance: Green color blends naturally with vegetation for landscape restoration
- Stable Structure: Quilting prevents layer separation during filling and long-term use
- Dual-Layer Protection: Inner twill provides tensile strength, outer nonwoven provides filtration
- Vegetation Support: Nonwoven surface supports seed germination and root growth
Applications
- Water Conservancy Embankment: River and coastal protection, anti-erosion reinforcement
- Ecological Slope Protection: Slope stabilization with integrated green coverage
- Cofferdam and Flood Control: Temporary cofferdams, sandbag alternative for flood barriers
- Artificial Wetland: Wetland restoration, ecological island construction
- Riverbank Reinforcement: River bank stabilization and anti-scour protection
- Land Reclamation: Boundary protection combined with geomembrane
