Geosynthetics Africa – Specialists in High-Flow Woven Monofilament Geotextiles for African Conditions
High-Flow Drainage & Filtration Solutions Using Woven Monofilament Geotextiles
Monofilament woven geotextiles engineered for applications requiring the highest flow rates, stable pore structures, and long-term filtration performance
Geosynthetics Africa supplies and supports woven monofilament geotextiles across Southern, Central, East, West, and North Africa for filtration- and drainage-critical applications.
Our FlowTex™ FT Series is specified where high water flow, resistance to clogging, and consistent pore geometry are required—making it suitable for dewatering, drainage, and hydraulic control in demanding civil and mining environments.
Why Choose FlowTex from Geosynthetics Africa?
Geosynthetics Africa is one of the few suppliers in Africa to clearly differentiate between slit-film woven geotextiles for reinforcement and monofilament woven geotextiles for filtration and drainage.
African projects demand materials that can withstand high loads, aggressive environments, and variable water quality – without performance drop-off. The FlowTex series offers:
1. High Permeability for Faster Drainage
With water permeability rates of up to 350 mm/s, these geotextiles enable rapid water release in drainage systems, filtration units, and dewatering setups. This high permittivity is maintained under load, unlike slit-film fabrics that flatten and choke flow.
2. Controlled Apparent Opening Size (AOS)
Precisely engineered pore sizes – from 180 μm (FT 180) to 600 μm (FT1000) – ensure effective fine particle retention while sustaining maximum flow rates. The uniformity of openings prevents fines from sealing the fabric.
3. Superior Anti-Clogging Performance
Monofilament construction resists bio-film buildup, silt blinding, and particle lodging – common failures in slit-film based dewatering bags traditionally being supplied across Africa. This means longer operational cycles and reduced maintenance.
4. Outstanding Mechanical Strength
Tensile strengths of up to 44 kN/m (MD) and high CBR puncture resistance (up to 6 kN) provide the robustness needed for heavy-duty handling, installation, and long-term service.
5. Chemical, UV & Abrasion Resistance
Manufactured from durable polyolefins, these fabrics resist degradation from acids, alkalis, saline conditions, and UV exposure – critical for African climates and marine/coastal works.
6. Installation Efficiency
Supplied in wide rolls (5.05–5.20 m x 100 m), these geotextiles reduce seams and speed up installation, saving time and labour in large-scale African projects.
Applications Across Africa
Geosynthetics Africa supplies FlowTex woven monofilament geotextiles for a range of critical applications:
Drainage Systems – subsoil drains, underdrains, trench drains, collector drains
Filtration Layers – retaining soil while allowing high water throughput in riverbanks, coastal works, and reservoir inlets
Dewatering Systems – in geotextile tubes, dewatering pads, and filtration units for mining, municipal, and industrial slurries
Scour & Erosion Control – under riprap and armour layers in marine and river projects
Sand & Rock Bags – geotextile containers for coastal defence and ballast applications
Infrastructure Protection – filtration wraps in road embankments, bridge abutments, and retaining walls

Outperforming Slit-Film Fabrics in Africa
Many African operators have faced slow dewatering cycles, bag failures, and costly downtime with slit-film fabrics. Problems include:
Clogging and blinding under organic-rich or fine sediments
Reduced flow under load due to tape-yarn compression
Edge tears and seam splits during handling
FlowTex woven monofilaments, supplied by Geosynthetics Africa, eliminate these issues with stable, round filament pores, sustained permeability, and superior tensile performance.
