Differences Between Geogrids and Geotextiles

  1. Geotextiles are manufactured for separation, filtration, and drainage purposes, whereas geogrids are specifically manufactured as a reinforcement material.

  2. A geogrid is unlikely to separate any type of fill. For instance, once the subgrade soils become saturated, it can easily flow through the geogrid apertures. However, the geotextile can allow the free movement of water from the soil into the aggregate layer, and vice versa.

  3. In general, it may seem that geogrids interlocking of the soil with the grid membrane makes it a superior form of reinforcement; however, the geotextile provides the separation function that ensures it maintains its thickness, service life, and long-term strength.

  4. Geogrids are passive resistance dependent reinforcement, whereas geotextiles are frictional resistance dependent reinforcement.

  5. Geotextile installation involves:

  • Grading

  • Evacuating

  • Allowing vegetation, and

  • Placing the separation geotextile directly on the prepared subgrade

Geogrid installation involves:

  • Planning the geogrid retaining wall

  • Evacuating

  • Sub-base and base stabilization

  • Gravel levelling

  • Laying retaining wall blocks
