Why does the bottom row of a retaining wall need to be buried?

Burying the first row (at least 10% of total wall height or minimum 4-6 inches) provides lateral soil resistance preventing the base from kicking out.

How much drainage gravel is needed behind a retaining wall?

A minimum 12-inch layer of clean crushed stone or gravel directly behind the wall prevents water pressure from building up and collapsing the wall.
