Tesla speeds Supercharger installations up with foundation that skips concrete (notebookcheck.net)

I've been eyeing a product called Diamond Piers for an upcoming project. They are small pre-poured footers that you secure by jack-hammering galvanized pipe through into the ground. No dig, no damage, quick install. The pipes get below the frostline, and since they are hollow, inspectors can just run a tape down them to check compliance.

As long as these gravel-filled piles are deep enough to avoid frost heaves, they should be fine.


the screen shot of the CAD, shows the plastec foundation pieces, on a standard plastic pallet mk1 eyball puts the underground distance @ 40"+ which will be below the frost line in the vast majority of locations. And, yes, its going to be a game changer for instalation, and any possible repairs or service requirements.......much like how Japanese infrastructure is installed in citys, where roads are covered in interlocking bricks, and under that is gravel, and then all the various utility and other systems, upgrades or repairs are done by removing and stacking the bricks, vacuming up the gravel, do the job, put it back together, often at night.


This seems very sensible for an earthquake zone.


The fact that they no longer require concrete to install is a huge win. Concrete is a very labour and co2 intensive material
