Types of Geosynthetics for Erosion Control

Types of Geosynthetics for Erosion Control

In simple terms, soil erosion is the shift of the upper layer of soil caused by water, ice, wind, or tillage. While this can be a relatively slow process it can cause a wide range of problems during construction and agriculture. For this reason, geosynthetics are used to stabilize land and for erosion control.

Sedimentation is the deposition of soil particles transported by water and wind. It happens when the medium in which the soil particles are carried, either air or water, is slowed long enough to allow particles to settle out. Sediment control goes in hand with erosion control and it’s designed to keep eroded soil on a construction site, so it doesn’t wash off and cause water pollution to a nearby location.

Geosynthetics are synthetic products used to solve civil engineering issues namely erosion and sedimentation. Geotextiles, geogrids, and geocells are some common categories of geosynthetics that are widely used in sediment and erosion control. Made in both synthetic and biodegradable options, geosynthetics are able to control sediment in your land and prevent further erosion.


Geotextiles are fabrics that have the ability to separate, filter, reinforce, protect, or drain soil. They are made of synthetic fibers, making them less susceptible to biodegradation. They consist of polypropylene or polyester fabric and can be knitted, woven or non-woven. These textiles are designed with the intent of improving and or managing soil, either for conservation or agricultural purposes. You can also use geotextiles in different engineering and construction projects.

If you need geosynthetics for separating soil types of stabilizing soft soils, geotextiles are a good option.


Geogrids are usually made from polymers such as polypropylene, polyvinyl alcohol, polyethylene or polyester to provide tensile reinforcement of soil. Geogrids are mainly used to reinforce retaining walls, as well as subbases or subsoils below roads or structures.

Geogrids consist of integrally connected ribs. One of the most commonly used geosynthetics, geogrids are effective at stabilizing and reinforcing soils. They're used in road foundations or weak soils. You can purchase different types of geogrids, including biaxial, uniaxial and multi-axial geogrids.

Geogrids are environmentally friendly and are used in multiple applications. Used for embankments, retaining walls, and composite structures, geogrids also offer resistance against bacteria and chemicals.


Cellular confinement systems, also known as geocells, are used as a durable material for protection and stability. Geocells efficiently maintain the soil’s compaction and create a stronger structure for both the infill and pavement.

Geocells are great for sediment control because they minimize soil movement with geotextile strips that expand into a honeycomb-like structure. You can use geocells for soil erosion or to stabilize soil.

Geocells are easy to install and are effective at preventing erosion or landslides by stabilizing the soil. They can also support heavy loads, even on weak soils.

Choosing the Right Geosynthetic for Your Project

Which type of geosynthetics you use for your engineering or construction project depends on the project specifications, soil characteristics, maintenance and installation. Find out the expected loads or environmental conditions to determine which material to use. Analyzing the soil is also crucial; for example, if the soil is acidic, you need polymers resistant to chemical degradation. Lastly, you need to ensure the geosynthetics are properly installed and maintained. You might need to hire professionals for installations or use seams and anchors to secure them.
