Existing wall ties are located using a metal detector to find their pattern and density, inspection holes are then drilled to view a sample of the ties using a high intensity boroscope. Where necessary sample ties may be removed for more detailed analysis. All sample holes / disturbed mortar joints being made good during the survey.

If the survey results indicate corroded or insufficient ties the report will recommend a suitable replacement strategy.
