Engineered Woven & Non-Woven Geosynthetic Sandbags for Hydraulic and Flood Control Applications
Designed for structural stability, controlled filtration, and long-term performance in African coastal and flood-prone environments.
Geosynthetics Africa supplies engineered geosynthetic sandbags designed for erosion control, flood protection, shoreline stabilisation, and hydraulic containment in demanding African conditions.
Our woven and non-woven geotextile sandbags are selected based on structural stability, controlled filtration, hydraulic exposure, and service life, ensuring reliable performance for both emergency flood response and long-term coastal and river protection works.
This engineering-led approach delivers predictable field performance, rapid deployment, and dependable results—far beyond conventional sandbag solutions.
Non-Woven Geosynthetic Sandbags (Small Bag Applications)
These non-woven geosynthetic sandbags are designed for light-duty hydraulic and erosion control applications where filtration, flexibility, and rapid deployment are required.
Manufactured using high-permeability non-woven polypropylene geotextiles, these bags are suitable for temporary flood protection, landscaping works, and low-energy erosion control, particularly where conformability and controlled filtration are more important than structural load capacity.
Product Range
For coastal protection, river training, and high-energy hydraulic applications, woven geosynthetic sandbags are recommended.
| Product Code | Dimensions (m) | Approx. Fill (kg) | Fabric Type | Typical Use |
|---|---|---|---|---|
| NW-S41 Sandbag | 0.55 × 0.30 × 0.30 | ~40 kg | Non-woven PP Geotextile | Temporary flood barriers, landscaping |
| NW-S51 Sandbag | 0.70 × 0.40 × 0.30 | ~70 kg | Non-woven PP Geotextile | Light erosion control, landscaping |
Typical Applications
Temporary flood diversion and emergency barriers
Riverbank lining in small streams and low-flow channels
Landscaping and erosion prevention on light slopes
Short-term sediment and soil containment
High-Strength Woven Geobags for Coastal, River & Flood Control Applications
For high-energy hydraulic and structural applications, Geosynthetics Africa supplies large-format, high-strength woven geobags engineered for extreme loading, hydraulic exposure, and long-term durability in coastal and riverine environments.
These geobags are designed using reinforced woven geotextile systems delivering tensile strengths up to 105 kN/m, combined with controlled filtration layers to ensure structural stability, resistance to abrasion, and sustained hydraulic performance under harsh field conditions.
Unlike conventional sandbags, these systems are intended for permanent and semi-permanent works where failure is not an option.
Performance Characteristics
Ultra-High Tensile Strength (60–105 kN/m) for structural stability
Excellent Hydraulic Performance under wave, current, and flood loading
Long-Term Durability in marine and fluvial environments
Large Unit Weights for resistance to uplift, displacement, and scour
Engineered Geometry for stacking, interlocking, and mass stability
This is engineered containment, not emergency bagging.

These high-strength woven geobags are specified where conventional sandbags, small geobags, or non-woven systems are structurally inadequate.
Installation & Handling
Small Geosynthetic Sandbags (40–70 kg)
Hand-filled for rapid deployment in emergency flood and light erosion control applications.Medium Geosynthetic Sandbags (400–1 400 kg)
Filled manually or via hopper and placed using light machinery for controlled hydraulic and structural works.Large Geosynthetic Geobags (1 800–4 000 kg)
Filled using hopper or hydraulic systems and placed by crane for high-energy coastal, river, and flood protection structures.Placement Method
Installed in overlapping “shingle-style” configurations to ensure mass stability, load transfer, and resistance to hydraulic uplift.Closure Options
Drawstring or sewn closures available for controlled filling and secure containment where required.
