Which consequence occurs when terrace retaining walls lack adequate drainage?

💡 Explanation

Hydrostatic pressure buildup increases when drainage is poor, causing wall instability via increased force against the terrace retaining wall, because saturated soil weighs more; therefore, wall failure is more probable, rather than enhanced leaching expected from efficient drainage.
