Landscaping and erosion control

What is erosion?
Erosion is the removal of solids (sediment, soil,
rock and other particles) in the natural
environment. It usually occurs due to transport by
wind, water, or ice; by down-slope creep of soil
and other material under the force of gravity

Why erosion control?
1. during the erosion process soil particles are transported, resulting in
the gradual deformation and destruction of slopes, banks, shores,
rivers bottoms, etc.
2. elsewhere, erosion causes undesirable sedimentation on
agricultural land and roads, in rivers and drainage systems, etc.

How can we control erosion?
• Existing slopes:
– prevent removal of the vegetation
– in case of new slopes protect the fertile surface layer by means of:
• coarse, less erodible surface
• flatter slopes / terraces
• surface cover with concrete, stones, plastic sheets
• temporary plastic sheets over surface in rain season
• geosynthetic mats
• biodegradable mats
• In case of slopes of ditches/channels:
– revetment structure
– concrete blocks
– heavy stones

What is a geosynthetic mat?
Geosynthetics mat is a three
dimensional erosion control
matting, made of Polyamide
monofilaments welded together
where they cross, with an open
space of over 95%.
For example : Enkamat®

How does geosynthetic mat function?
Geosynthetic mat helps nature to establish a natural, vegetation cover,
as it :
• acts as an artificial root-system
• holds soil particles and seeds
• reduces water and wind velocities
• creates a micro-climate and favours germination of seeds
• reinforces the vegetation cover in the root-zone

Fields of application
• erosion prevention for embankments and slopes
• protection of riverbanks against erosion
• support of vegetation on steep slopes and geomembranes

Geosynthetic mats - types
There are a lot of types in the market
for different applications.
• flatback, open mat
• reinforced with a woven fabric
• factory filled with bitumen-bound
Ask you landscaping architect, designer or supplier to decide the suitable type
for your area and type of application
