Generally footing thickness of 1 to 1.5 times the wall thickness will be adequate. WebMar 4, 2024 · The self-weight component of the retaining wall should be factored down or to be multiplied by weight reduction factor (0.9) to account for uncertainty because they are “stabilizing” in this context. Hence, Weight due to soil: W 1 = 18kN/m 3 x 0.6m x 0.625m x 1.0m = 6.75kN Weight due to footing: W 2 = 0.9 x 25kN/m 3 x 0.25m x 1.5m x 1.0m = 8.44kN
