High-Flow PolyTape™ Silt Fence by Geosynthetics Africa
High-Strength, UV-Stabilised Woven Geotextile Silt Fences for Reliable Sediment Control
Engineered Sediment Control for Construction & Mining Across Africa
PolyTape™ Silt Fence by Geosynthetics Africa is a high-performance, strength-rated silt fence system engineered to control sediment and runoff in civil, infrastructure, and mining environments where conventional 28 kN construction silt fences fail.
Unlike generic silt fencing designed for low-risk, short-term applications, PolyTape™ is manufactured from UV-stabilised woven slit-film polypropylene geotextiles and supplied in multiple engineered tensile classes, allowing engineers to specify performance to suit site risk, flow energy, and installation duration.
Why PolyTape™ Is the Benchmark Silt Fence System
High-Flow Filtration Without Clogging
PolyTape™ fabrics are designed with a controlled apparent opening size (<180 microns) to retain fine silt and clay particles while maintaining high water flow rates. This prevents ponding, overtopping, and fence collapse commonly seen with coarse or poorly balanced fabrics.
Strength-Rated, Not One-Size-Fits-All
Most silt fences in South Africa are limited to a single low-strength grade. PolyTape™ is available in 30 kN, 45 kN, 60 kN, and 105 kN tensile classes, enabling correct selection for:
Higher runoff velocities
Longer fence runs
Steeper slopes
Mining and high-abuse environments
High Puncture & Tear Resistance
The woven slit-film construction provides excellent puncture resistance, reducing damage during installation and maintaining integrity under sediment load and debris impact.
UV-Stabilised for African Conditions
PolyTape™ is engineered for prolonged exposure to African sun and soil conditions, with resistance to UV degradation, alkalis, acids, bacteria, and common soil chemicals.
Factory-Finished Rolls for Reliable Installation
All PolyTape™ silt fence rolls are precision-cut with sealed selvedge edges, reducing fraying, improving handling, and speeding up site installation.
Typical Applications
Construction site runoff and sediment control
Road and highway earthworks
Rail and linear infrastructure corridors
Mining operations and tailings facilities
Bulk cut-and-fill earthworks
Stream, riverbank, and environmentally sensitive zones
Complete Silt Fence System – Supply & Installation
Geosynthetics Africa supplies a fully integrated silt fence system, not just fabric:
PolyTape™ woven silt fence rolls (strength-rated)
Untreated timber posts (minimum 900 mm embedment capability)
Galvanised tie wire and fixing accessories
Installation guidelines aligned with best-practice sediment control
Our experienced teams also provide professional installation services across Africa, including trench anchoring, contour-following layouts, and correct elevation alignment to prevent bypass and failure.
Why Engineers Choose Geosynthetics Africa
Strength-graded silt fence systems (30–105 kN/m)
Controlled filtration for fine silt retention
High-flow performance without clogging
Mining-grade options for high-risk sites
Africa-wide delivery, stockholding, and technical support
Proven experience across civil, infrastructure, and mining projects
If a project still specifies “standard silt fence,” it is under-specified.

Engineer’s Selection Note
Select silt fence grade based on runoff energy, slope length, sediment load, and installation duration. Under-specification leads to failure, rework, and environmental non-compliance.
