Soilsaver Erosion Control BlanketsA Practical Solution for Slope Protection in South Africa
Erosion is a common problem across South Africa—especially on exposed slopes, new developments, road embankments, and areas affected by stormwater runoff. Once topsoil starts washing away, the damage spreads fast, leaving behind unsafe ground, exposed subsoil, and costly repairs.
That’s why Soilsaver erosion control blankets are widely used as a reliable, eco-friendly solution to stabilise soil and help vegetation establish naturally.
At Civil Structural & Eco-Engineering, we provide practical erosion control solutions that are suitable for South African site conditions, including the use of Soilsaver erosion control blankets for long-term slope protection and rehabilitation.
What Are Soilsaver Erosion Control Blankets?
Soilsaver erosion control blankets are protective mats designed to cover exposed soil and prevent erosion caused by rainfall, runoff, and wind. They work by stabilising the soil surface while allowing seeds and vegetation to grow through the blanket.
These blankets are typically used on:
The blanket acts as a temporary protective layer that supports long-term soil stability.
How Soilsaver Blankets Help Prevent Erosion?
Erosion control blankets focus on the main causes of soil loss: water impact and soil movement.
Reducing Surface Washaway
Heavy rainfall breaks up exposed soil and creates runoff paths. Soilsaver blankets protect the soil surface and reduce erosion by slowing down water movement over the slope.
Protecting Topsoil During Vegetation Establishment
Vegetation is one of the best long-term erosion control methods—but it takes time to grow. Soilsaver blankets protect the soil during this critical period so grass and plants can establish.
Improving Slope Stability
By stabilising loose soil, erosion control blankets help reduce the risk of:
- Surface Slumping
- Rill Erosion (Small Channels Forming)
- Exposed Roots And Undercut Areas
Where Soilsaver Erosion Control Blankets Are Most Effective?
Soilsaver blankets can be used in many civil and eco-engineering applications.
Slope Protection on Developments
Freshly cut or filled slopes often erode quickly without protection.
Ideal for:
- Residential Developments
- Commercial Building Sites
- Estates And Lodges
- Retaining Wall Backfill Slopes
Stormwater Runoff and Drainage Areas
Runoff from roofs, roads, and paved areas often concentrates in one direction.
Ideal for:
- Runoff Pathways
- Discharge Zones (Mild Flows)
- Stabilising Surfaces Around Drainage Structures
For high-flow channels or riverbanks, gabions or reno mattresses may be required instead.
Road Embankments and Cuttings
Roadside slopes are exposed and often affected by fast stormwater runoff.
Ideal for:
- Road Cuttings
- Embankments
- Access Road Stabilisation
- Verge Rehabilitation
Rehabilitation and Environmental Restoration
Soilsaver blankets are widely used for rehabilitation because they support natural regrowth.
Ideal for:
- Disturbed Ground Rehabilitation
- Mine And Industrial Rehabilitation
- Landscaping Restoration Areas
Benefits of Soilsaver Erosion Control Blankets
Soilsaver blankets provide multiple advantages for soil protection projects.
Fast and Effective Erosion Protection
They provide immediate soil protection after installation, which is crucial before the next rainfall.
Eco-Friendly and Low Impact
They reduce the need for hard structures on mild-to-moderate erosion areas and support natural rehabilitation.
Improves Project Finish and Site Appearance
A stabilised, green slope looks cleaner and more professional than exposed eroded soil.
Supports Natural Vegetation Growth
Blankets allow grass and plants to grow through and form long-term stability.
Reduces Maintenance and Repair Costs
Preventing washaways early saves money compared to rebuilding slopes after erosion occurs.
Soilsaver vs Other Erosion Control Methods
Not every site needs gabions or heavy structural solutions. Soilsaver blankets are most effective when used correctly.

When You May Need Stronger Solutions?
In high-risk areas, a blanket alone may not be enough.
You may need gabions, reno mattresses, pitching, or reinforced drainage solutions if you have:
Deep Washaways And Active Gullies
Fast-Flowing Stormwater Channels
Riverbanks With

Installation Guidelines for Soilsaver Erosion Control BlanketsCorrect installation is essential for performance. Poor installation can result in the blanket lifting, tearing, or failing during rain.
Site Preparation Before Installation
Before placing the blanket:
- Grade And Shape The Slope Smoothly
- Remove Rocks, Debris, And Sharp Objects
- Compact Loose Soil Where Required
- Ensure Runoff Has A Controlled Flow Path
Seeding and Soil Conditioning (If Required)
In many cases, blankets are installed with:
- Grass Seeding
- Fertiliser Or Compost
- Topsoil Improvement
This supports faster vegetation growth.
Blanket Placement and Overlaps
Soilsaver blankets should be laid:
- In The Direction Of Water Flow
- With Sufficient Overlap At Joints
- Securely Fixed Into The Soil Using Appropriate Pins/Staples
Anchoring and Securing the Blanket
Proper anchoring prevents movement caused by:
- Wind Uplift
- Heavy Rainfall Runoff
- Water Flowing Under The Blanket
Edges and joins must be secure for long-term performance.
Common Mistakes to Avoid
To get the best results, avoid these common erosion blanket problems:
Installing on an Unstable or Poorly Shaped Slope
If the soil is loose or uneven, water will still find channels and erode underneath the blanket.
Not Controlling Stormwater Above the Slope
If runoff is concentrated from a roof, road, or drainage outlet, it may overwhelm the blanket and cause failure.
Insufficient Anchoring
Blankets can lift or shift if not pinned properly, reducing effectiveness immediately.
Using Blankets in High-Flow Channels
Blankets are not a replacement for gabions or reinforced systems in high-velocity water zones.
