Problem Diagnosis
Washouts
Washouts identify where runoff has removed material. Restoring levels without changing the erosive flow can produce the same failure again.
Plan the surface handover
BeforeInspect the upstream catchment, discharge route and remaining stability.
Work stageAddress the drainage or erosion-control detail before replacing suitable material.
AfterRe-establish and protect the surface with the appropriate stabilisation method.
What to verify
Inspect during later runoff and check the repair's edges.
Diagnosis should distinguish the visible symptom from its cause. Record whether the fault appeared after traffic, a water event, settlement or earlier earthworks. That history helps decide whether the response is a local surface correction, a drainage intervention or a more substantial investigation.
Scope and limits
Deep scour, unstable banks or structural damage may require specialist work.
