Birdbath A birdbath is a shallow depression in concrete or asphalt that collects water after rainfall. The term describes the shape of the depression rather than a structural feature.
Birdbaths usually result from settlement, improper finishing, or inadequate grading during construction. Persistent standing water can contribute to surface deterioration, staining, and freeze-thaw damage over time. Repair methods depend on the size and cause of the depression.
