Map gravel and sand deposits determine:

Depth of overburden

Depth of deposit

Quantify volumes

Assess quality of gravel (sorted or pit-run)

Perform multiple transects within one hour

Survey depths up to 4 metres or more (depending on soil conditions - see chart)

GPR can be tied to a GPS to yield precise locations

3-D software allows results to be obtained with x, y and z coordinates

Determine depth to bedrock under proposed roads, quantify volumes, assess quality of gravel (sorted or pitrun)
