taller walls will need tie-backs and deadmen for extra stability

Generated explanation

Two cross sections illustrate precast concrete retaining wall systems supporting soil at different elevations. The left wall consists of stacked concrete units stepped back toward the retained soil, with gravel drainage backfill behind the wall. The right wall uses interlocking concrete units and a horizontal tie-back connected to a buried deadman in the retained soil. Both sections identify undisturbed soil and topsoil at the lower grade. An annotation states that taller walls need tie-backs and deadmen for extra stability.
