GEOSYNTHETICS SOUTH AFRICA

SoilLock Straw Erosion Blankets

Geosynthetics South Africa supplies and installs SoilLock Straw Erosion Blankets across South Africa and Southern Africa.

Our straw erosion blankets provide surface cover during vegetation establishment on prepared ground. We supply and install the blanket with the specified seeding, fixing and overlap arrangements for landscaping and rehabilitation works.

  • Surface cover for newly seeded ground
  • Soil and vegetation-establishment support

Straw Cellulose SCB Blankets South Africa
Straw Cellulose Fibre Blanket

Manufactured from agricultural straw fibres secured between photodegradable netting and stitched with biodegradable yarn at controlled spacing, Straw SoilLock™ provides immediate soil protection while allowing vegetation to establish and permanently stabilise the slope.

ENGINEERING CLASSIFICATION

Straw SoilLock™ is classified as:

Type 1D Erosion Control Blanket

This classification confirms suitability for:

  • temporary erosion control

  • low-to-moderate flow channels

  • slopes requiring vegetation establishment

  • construction stabilisation phases

PERFORMANCE CHARACTERISTICS

Straw SoilLock™ is engineered to deliver the key functions required by consultants and contractors:

Immediate Erosion Protection

Prevents soil displacement during initial rainfall events before vegetation establishment.

Vegetation Support

High water absorption capacity supports seed germination and root development.

Surface Stabilisation

Provides physical soil confinement and reduces erosion velocity.

Controlled Degradation

Breaks down naturally once vegetation provides permanent reinforcement.


Specify the blanket and fixing system

Select the blanket construction and protection period against the slope, soil, rainfall and expected runoff. Request the current product specification, roll dimensions and installation guidance. Confirm netting and yarn composition where biodegradation is a project requirement.

Site preparation, anchor details, seed selection and maintenance influence the result. A blanket does not replace drainage or a designed solution for concentrated flow.

Typical Specification Conditions

Engineers typically specify straw fibre blankets where:

  • vegetation establishment is expected within 6-12 months

  • slopes are moderate (generally flatter than 2:1)

  • rainfall exposure is seasonal or moderate

  • temporary erosion protection is required

  • budget optimisation is important

Request a Straw SoilLock™ quotation

Send the area, product specification, slope information, delivery location and fixing requirements. We can quote materials, delivery and installation where included in the scope. Confirm current blanket construction, nominal mass and roll dimensions in the quotation.

Applications and uses

We supply and install this product for:

  • Surface soil protection during vegetation establishment on prepared slopes.
  • Rehabilitation, landscaping and erosion-control works where the selected blanket suits the exposure.

WHERE STRAW SOILLOCK™ IS SPECIFIED

Engineers select straw fibre blankets where temporary stabilisation is required and vegetation is expected to establish quickly.

Typical projects include:

  • road embankments

  • construction earthworks

  • infrastructure corridors

  • residential developments

  • pipeline servitudes

  • stormwater channels

  • stockpile stabilisation

  • rehabilitation works


Where Straw Cellulose Fibre SoilLock™ Blankets Are Specified

Straw SoilLock™ 300gsm erosion control blankets are designed for temporary stabilisation applications where immediate soil protection and rapid vegetation establishment are required. Their Type 1D classification and hydraulic performance characteristics make them suitable for a wide range of civil, environmental, mining, and infrastructure projects requiring short-term erosion control.

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.

INSTALLATION PRINCIPLES 

Correct installation is essential for performance.

Standard procedure:

  1. Grade and compact surface

  2. Remove debris

  3. Apply seed and fertiliser

  4. Place blanket in flow direction

  5. Overlap edges 100-150 mm

  6. Anchor crest in trench

  7. Stake at 1-1.5 m spacing

  8. Ensure full soil contact

Improper anchoring is the most common cause of erosion blanket failure.

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.
