A retaining wall calculator estimates the materials needed (blocks, concrete, drainage) for a wall designed to hold back soil or create level terraces. Wall stability depends critically on height, soil pressure, and drainage.
💡
Pro Tip
Never build a retaining wall without adequate drainage behind it — hydrostatic pressure from saturated soil is the leading cause of retaining wall failure.
