When there are harsh weather conditions such as rainfall and strong winds, bare and newly planted soil will erode. This causes sediments to pollute water bodies.
In order to prevent such pollution, erosion control blankets (also known as coco blankets) are used. These materials are made of coconut fibres, and are used as sediment control measures for effectively minimising the erosive effect of rainfall.

Advantages of Erosion Control Blanket
- Exceptional water absorption
A soil erosion blanket is able to absorb a huge volume of water from its environment. This quality is essential in ensuring its effectiveness in erosion control.
- High tensile strength
These blankets are able to withstand the harshest weather conditions, without breaking under high tension.
As a biodegradable material, these mats can be decomposed by bacteria which then prevents pollution.
- Facilitates soil moisture retention
Moisture in soil is critical for plants, as well as in the development of weather patterns. This is something that erosion control blankets can facilitate.
- Increases water filtration into the soil
The weight of the erosion control blanket boosts water filtration, as it is filtered and cleaned through physical, chemical and biological processes.
- Prevents soil erosion by holding seed saplings in place
Common Applications of Erosion Control Blankets
- Golf course
- Building and residential projects
- Reclamation of mined land
- Streambanks and shorelines
- Temporary erosion protection during construction
- Fill slopes
FAQs About Erosion Control Blankets
The purpose of erosion control blankets is to prevent soil from shifting and encourage plant growth. These products are often used in areas that are highly susceptible to erosion such as steep slopes, riverbanks and coastlines.
- Photodegradable erosion control blankets
The netting of photodegradable erosion control blankets are usually made of plastic that contains UV stabilisers. These blankets will decompose after prolonged exposure to sunlight.
- Biodegradable erosion control blankets
Natural fibres are commonly used to create biodegradable erosion control blankets. They will break down over time and leave minimal environmental impact.
- Permanent erosion control blankets
These blankets last the longest as they are made out of synthetic fibres that do not decompose.

Erosion control blankets that are biodegradable in nature are able to last between 3 months to 3 years. On the other hand, permanent erosion control blankets which are non-biodegradable can last up to 10 years.
Erosion control blankets are relatively easy to install and require 3 simple steps:
1. Smoothen soil and plant seeds
Smoothen the surface of the soil by removing debris such as rocks and pebbles before planting the seeds. Apply fertiliser to the soil if necessary.
2. Secure the blanket
Place the blanket over the soil and secure it with landscaping staples to ensure that it will stay in place.
3. Overlap the blankets (if necessary)
If you are using numerous nets, they should overlap one another to prevent any gaps.
