Diagnosis and treatment of defective cavity wall ties

Abstract

The failure of a wall in a Welsh farmhouse in the middle 1960s was regarded as an isolated problem when it was discovered that the cause of the failure was corrosion on the cavity wall ties. This was the first failure of a wall tie that was reported to the Building Research Establishment. Within a few years of the Welsh report, other instances of this type of failure were being reported to the BRE. The subsequent investigation of the durability of wall ties revealed a failure in the galvanised surface to the metal of the ties. Similar ties were subjected to close examination by the BRE.
