Garland’s expansion across the Blackland Prairie, with its deep clay soils and scattered limestone shelves, means every construction project here sits on a layered geological puzzle. We have seen too many projects stall because the borehole spacing missed a five-foot drop in bedrock or a soft channel fill that only continuous profiling could catch. Seismic tomography fills that gap. The method sends shear and compression waves through the subsurface, and our processing turns travel-time data into a velocity cross-section that reveals stratigraphy in detail. For projects near Lake Ray Hubbard or along the Rowlett Creek floodplain, where alluvial deposits shift over short distances, this geophysical approach becomes a cost-saver. We often pair it with SPT drilling to calibrate velocities against actual blow counts at key locations, giving you both coverage and verification in one campaign.
Seismic velocity sections let you see between the boreholes—where the real geotechnical risk usually hides.
