What is geogridGeogrid is one type of geosynthetic material used for reinforcing soil and similar material. It is a basically a flexible wiry mesh made out of synthetic materials. A properly made geogrid is very well capable of soil retention and slope stabilization.
Geogrids are available in many shapes and sizes, and they can be made from a variety of materials as well. However, as the strength and other capabilities vary a lot depending upon those factors directly, it is mandatory to check your needs and test out the geogrid before you utilize it in your construction.
Why are geogrids neededCompared to soils, geogrids are much stronger in tension. And that is the very reason why they are used in reinforcing retaining walls, sub bases or sub soils below ground construction such as highways or large structure footings. This allows the force coming from above to spread over a much wider area, and to hold the soil together as the downward force tried to expand the soil sideways.
A retaining wall cannot get very tall, but sometimes you need the height to get the job done. In fact, no retaining wall can be any taller than 4 feet. If you try to go above that, you will need to use a geogrid to reinforce the retaining wall. With proper design and good quality geogrid, you can build retaining walls as high as 30 to 40 feet!
To be clear, when the weight of the retaining wall alone isn’t good enough to hold the soil loads in, you need the help of a geogrid to reinforce the retaining wall. This will provide the additional soil reinforcement necessary to stabilize the wall. Not only that, the geogrid reinforcement will make sure your retaining wall is long-lasting as well as functional and attractive.
