Geogrids and geotextiles are sometimes used interchangeably. Like hydroseeding and sod, Geogrids and geotextiles both aim to prevent soil erosion. Are you wondering if there are any differences between geogrid and geotextile? Let’s explore the geotextiles and geogrids.
What Is a Geogrid?
A geogrid is a modern, affordable solution to soil or landscape reinforcement and stability. It closely resembles an open marsh held together by polymers. Geogrids are made using several materials, including polyethylene, polyester, and polypropylene.
There are different types of geogrids, including:
- Woven Geogrids: Woven geogrids are made by weaving, hence the name. This type of geogrid is made by transversing the ribs of polypropylene coated with polyester strands. The crossings are then united by weaving or knitting before adding an extra coating to ensure that the complete unit is well preserved.
- Extruded Geogrid: A geogrid that has been extruded is made using polymers that have been stretched or extruded. The integrated structure that results can go either in a biaxial or uniaxial direction, with a geogrid that is quite stiff and stronger than a woven geogrid.
- Bonded Geogrids: A bonded geogrid is made by bringing together two or more strands of material at right angles.

What Is a Geotextile?
Geotextiles are permeable textiles used to hold together the earth, dirt, or soil, especially in geotechnical engineering-related projects or systems. They are also used in the agriculture industry as a barrier that prevents weeds from growing through the soil and into the garden, to control pests, alongside mulch to suppress weeds, to retain moisture in gardens, and to reinforce the stability of a slope.
The different types of geotextiles include:
- Woven Geotextile: A woven geotextile is made by consistently interweaving yarns in two directions, giving rise to a cloth-like material. It is suitable for projects that don’t require excessive strain, such as drainage, soil separation, and filtration projects.
- Non-Woven Geotextiles: These are plain geotextiles with no obvious design. The non-obvious design results from the random attachment of threads in a mat using a needle, and then resin or heat is applied for bonding. That explains why non-woven geotextiles are suitable for high strain and can stretch significantly to withstand a heavy load.

Geogrid vs. Geotextile Fabric
There are significant differences between geotextiles and geogrids. For instance, geotextiles are suitable for filtration, separation, and drainage purposes, and geogrids are more suitable as material for construction reinforcement. At the same time, geogrids are suitable for projects that require water to flow through because of their perforations, while geotextiles are suitable in areas that need water to flow from the soil to the aggregate layer.
