When a retaining wall fails, it is almost never a surprise to the wall. The signs were there. Horizontal cracking indicates bending stress at design limits. Vertical cracks can mean differential settlement. Bulging means rotation - the soil is winning. Base displacement and lost batter are visible precursors to catastrophic failure. Walls that fail suddenly almost always had a distress history. Inspection matters. #MrBarricade #RetainingWalls #CivilEngineering #Infrastructure
