ENGINEERING PERFORMANCE & DESIGN CONSIDERATIONS
Selecting the correct erosion control blanket is a critical engineering decision that directly affects slope stability, sediment loss, vegetation establishment and long-term rehabilitation success. Coconut fibre blankets are specified where projects require both immediate erosion protection and natural reinforcement through vegetation growth.
Geosynthetics South Africa supplies performance-verified coir blankets designed for demanding African environmental conditions including high rainfall intensity, erodible soils, steep slopes, and temperature extremes. Each blanket grade is engineered to balance hydraulic resistance, tensile strength, soil retention and biodegradation rate so that protection remains effective until vegetation root systems permanently stabilise the soil structure.

Installation and technical guidance
Design and procurement inputs
Choose fibre type, expected functional longevity, slope and hydraulic exposure, seed and soil requirements, anchoring and overlaps. Erosion blankets are not a substitute for a slope-stability design.
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.
Request a product-specific quotation →INSTALLATION GUIDELINES
Grade and compact slope surface.
Remove loose debris.
Seed and fertilise prior to blanket placement.
Install blanket in direction of water flow.
Overlap 100-150mm longitudinally.
Anchor in trench at crest (typically 300mm x 300mm minimum).
Use biodegradable stakes at 1-1.5m centres (site dependent).
Ensure full soil contact.
Proper anchoring is critical for long-term performance.
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.
