Stone facade surveys

The UK has a large number of historic stone clad buildings. These stone facades are affixed to the main building structure by cramps and pins. The stone work is often intricately shaped and cut to fit together perfectly. Inevitably there will be no drawings or information on how a particular facade is constructed.

By scanning the facade with radar our surveyors can accurately determine the thickness of each stone block, including any variation. Radar can also determine the presence of voids behind or within the stone work and the position, depth and approximate size of the cramps and other embedded metal can also be mapped.

All the collected site data will be analysed and the identified stone thickness and the locations and depths of the cramps is be marked onto a CAD elevation drawing. CAD sketches, photographs and annotated radargrams showing detail of detected features will also be included as appropriate.
