FlowTex™ Mono Dewatering Bag 1x1x1 – High Flow Monofilament
R700
Premium high-flow dewatering bag manufactured from 180µm monofilament woven geotextile, delivering superior filtration of fine silt without clogging. Designed for high-strength, long-duration dewatering applications where slit film bags fail.
The Most Advanced Dewatering Bag in Africa
Non-Clogging. Fine Silt Retention. High Strength.
Description
Engineered for Performance Where Others Fail
The FlowTex™ Mono Dewatering Bag is a next-generation dewatering solution engineered using monofilament woven geotextile, delivering unmatched performance in filtration, durability, and flow efficiency.
Unlike traditional slit film dewatering bags that blind and clog under fine sediment loads, FlowTex™ Mono maintains continuous flow and filtration efficiency, even under high silt conditions.
Why Monofilament Wins (Technical Advantage)
- 180µm Controlled Opening Size → Captures fine silt and clay
- Non-Clogging Structure → Maintains flow under high solids loading
- Superior Permeability → Faster dewatering cycles
- 40 kN/m Tensile Strength → Handles demanding site conditions
- UV Stabilized → Long-term outdoor exposure performance
- Opening size: 180 µm
- Tensile strength: 40 kN/m (MD & CMD)
- Permeability: ~50 mm/s
Why Standard Dewatering Bags Fail
| Issue | Traditional Slit Film Bags |
|---|---|
| Clogging / Blinding | ❌ Frequent |
| Fine Silt Retention | ❌ Poor (>200µm openings) |
| Flow Efficiency | ❌ Reduces over time |
| Strength | ~30 kN/m |
| Lifecycle | Short |
