The following formulas apply to the wall embedment depth when a slope occurs in front of the wall base.

H' ÷ 20 = Embedment for a level slope (A)
(minimum 6" or 0.50'[0.15m])

H' ÷ 10 = Embedment for a 3h:1v slope (B)

H' ÷ 7 = Embedment for a 2h:1v slope (C)

Examples:

Wall Height of 10' ÷ 20 = 0.5' Embedment

Wall Height of 10' ÷ 10 = 1.0' Embedment

Wall Height of 10' ÷ 7 = 1.42' Embedment
