PolyTape Silt Fence
Our PolyTape silt fence helps retain sediment in construction runoff before it leaves the disturbed area. We manufacture and supply the fabric and install the fence with the required supports, trenching and returns.


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.

Installation and technical guidance
Design and procurement inputs
Limit contributing catchment and flow, key the fabric into the soil, provide suitable support and maintain sediment-storage capacity. Silt fence is not intended to block a watercourse or withstand concentrated flow.
Provide the product grade or performance specification, drawings or BOQ, quantities, site location and required date. We will define supply, delivery and any agreed installation and QA/QC responsibilities in the quotation.

All PolyTape™ silt fence rolls are precision-cut with sealed selvedge edges, reducing fraying, improving handling, and speeding up site installation.
Complete Silt Fence System - Supply & Installation
Geosynthetics South 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.
PolyTape™ Silt Fence Variants (Strength Selection)
PolyTape™ 30
30 / 30 kN/m (MD/CD)
Heavy-duty upgrade to traditional construction silt fence for general civil works and road projects.
PolyTape™ 45
45 / 45 kN/m
Designed for higher runoff energy, longer fence runs, and more demanding construction sites.
PolyTape™ 60
60 / 60 kN/m
Mining-grade silt fence for haul roads, bulk earthworks, and high-sediment environments.
PolyTape™ 105
105 / 105 kN/m
Ultra-high-strength silt fence for extreme runoff zones, tailings areas, and critical environmental protection where failure is unacceptable.
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.
Quality & Performance Commitment
High-quality product standard guaranteed.
Geosynthetics South Africa delivers engineered geosynthetic solutions designed to solve complex erosion and sediment control challenges across Africa.
SELECTION · SPECIFICATION · PROJECT SUPPLY
Choose the right specification
Match the erosion or confinement system to slope geometry, soil, water exposure, loading and the intended finish.
- Identify whether the duty is surface erosion, cellular confinement or a cementitious lining.
- Confirm the exact product, substrate, anchorage, infill and joint or overlap details.
- Use the product procedure and engineered layout rather than transferring fixing rules between systems.
Define the quality records
Inspect product identity, prepared ground, fixing and continuity, then record infill or activation and any specified acceptance checks.
For a useful quotation: send the grade or performance specification, quantity, location, required date and scope. Availability, delivery and installation responsibilities are confirmed in the quotation.
