About This Course

Retaining structures and wing walls are essential to the performance and stability of bridge approaches, yet they often fail due to poor integration between soil behaviour, structural detailing, drainage, and backfill operations. This course gives learners a clear, practical understanding of how retaining systems work, the factors that influence their stability, and how to design and construct them effectively. Using real project examples, the course explores earth pressures, material selection, compaction, drainage, reinforcement, and common failure mechanisms. Ideal for designers, site engineers, QA/QC professionals, project managers, procurement specialists, maintenance teams, and students, it equips participants to evaluate retaining solutions, review construction methods, identify risks, and ensure durable, stable bridge approaches.
