Ground Penetration Radar

Ground Penetrating Radar (GPR) is a rapid, cost-effect and non-intrusive survey method with a wide range of applications; including service location, archaeological, structural investigations, pavement assessments, geological investigations. The instrument and antenna is mounted on a cart and pushed or towed across the survey area allowing 100’s m to Km’s of data to be surveying in single day, reducing the number and need of direct sampling (i.e. Trial pits and slit trenches).

This also helps minimise the amount of disturbance to local services, traffic etc as no digging/drilling is required during the GPR survey. The method can also be used as a quick reconnaissance tool to help target areas for further investigation. Direct investigation of identified anomalies is required to help confirm location.

      

The method provides detailed images of the subsurface highlighting pipe and cable locations and their depth up to an accuracy of 1 cm, as well as providing information about general ground conditions and structures.Quality and depth penetration of the data depends on ground conditions. Highly reflective materials close to the surface i.e. metal bars may mask deeper anomalies.
