The Grid That Doubles the Strength of the Ground

Of course, you need "forever plastics" to make this work long term. It's like everything else where you have a material with decent compressive strength but weak tensile strength. You need something with some tensile strength to hold it together. That's what rebar does. It's why rebar rusting out destroys concrete structures. The same problem applies to geotextile containment of dirt. If the textile degrades, it's just a pile of dirt, in a place where a pile of dirt isn't enough.

The more traditional approach is to surround dirt or rubble with something that has more tensile strength. Some Egyptian pyramids were built that way. One of them fell down because the outward pressure from the load above was not sufficiently contained. Traditional stone construction of large structures is all about containing that outward push. That's what flying buttresses and bridge abutments do.

A few of my local parks have used this technique in their parking lots. I didn’t know they were called “geo-cells” so that’s interesting. They filled them with gravel, and it definitely seems to work well. I imagine it was a good way to save some budget versus a traditional paved parking lot

Interesting concept; horrible writing.
