Problem: The construction consists of an outer and inner layer of stone with random rubble infill. The outer layer is bulging away from the inner one.
Typical symptoms are pictured below including the appearance of a gap in a reveal where the wall has moved away from the window frame and internally where a gap has opened up between the wall and skirting.
Wall stabilisation actions: For this type of consolidation anchors are typically installed at the same density as for standard wall ties,at staggered centres.
