Geophysical surveys allow us to see below the ground’s surface for potential archaeology, without the need to excavate. It has the benefit of being able to cover large areas and can provide insights into what may be encountered during an excavation or development.

​

It is rarely used as a stand-alone technique, as the results can be inconclusive. It is often used in conjunction with evaluation trenches, where it can provide helpful information to guide where trenches are best placed.

​

​CBAS can undertake both resistivity and magnetometry surveys. We also have access to ground penetrating radar surveys using a specialist local service.

 

The actual survey to be implemented will depend upon various factors, such as the ground conditions and underlying geology, and the type of archaeological remains that may be present. Any size of survey can be undertaken. We can also process existing survey data, digital or hard-copy format, and can integrate geophysical survey results with other landscape surveys and desk-based data.
