(2007)</em></p><p><strong>Method Summary</strong></p><p>Representative samples of the grout or concrete mix must be obtained at the project site for QC/QA testing. The ideal location and time to obtain samples for testing is at the point of discharge into the soil and after the mix has been pumped through the lines and the auger, as the properties (especially workability) can be changed by pumping extended distances.
