I put my thermo pex under the gravel driveway. I put it 6 to 7 feet deep at the driveway and then came back up to 2 ft depth through the yard. Rented a mini excavator to put it in. I have semi's driving over it. Not often but they still make deliveries.
It does not bend easy. It bends about as good as a frozen garden hose.
