Damp line appears along wall-to-slab junction.
Inspect upstand height, chase or termination, cracks and coping; trace moisture after wind-driven rain.
Movement and a missing or failed termination permit water behind the membrane.
Repair cracks, form an appropriate cove or transition and reinstate a compatible upstand and termination.
Prepare sound surfaces; reinforce the junction where specified and protect exposed edges.
Inspect termination continuity and test the junction under controlled wetting.
A horizontal coating alone cannot bridge an unaddressed moving junction.
