My uncle told me to always use a 3/8 inch joint for a garden wall, and I finally listened after a winter of frost heave.

Man, my neighbor skipped the gravel base and his whole patio shifted like a tectonic plate.

What about drainage behind the wall though? That matters more than joint size for frost heave.

Eh, overthinking it a bit, frost heave is usually not that bad.

Wait, you had a whole winter of frost heave damage? That sounds like a nightmare to fix. Glad the new joint size is working out for you.
