After finishing a paving job a local paving contractor was audited through physical testing. Several core drills were used to show that the amount of asphalt laid was not thick enough in certain areas. The contractor faced heavy fines and having to potentially replace entire sections of asphalt costing them tens of thousands of dollars. They were sure they placed enough and hired Echo GPR Services to scan the entire lot to determine asphalt thicknesses. Using the cored data, Echo calibrated the GPR to the asphalt and mapped out the entire parking lot. Using a statistical breakdown it was found that the contractor was in compliance and did not have to replace the lot. Echo saved the contractor a major financial loss on the project and assured the building owner they received what they had paid for.
