General view of the GPR area of work

To detect low-density soil zones under the floor slabs, an analysis was made of the changes in the attribute of the wave field Q-factor (the ratio of the center frequency to the width of the signal spectrum). Elevated values ​​of the attribute Q-factor correspond to areas with a low density of the underlying soil. The sections of this attribute were built and combined into 3D assemblies. The figure below shows the horizontal section of the 3D assembly directly below the floor construction with the detected zones of low-density soil (blue corresponds to dense ground, yellow and red - low-density soil):

To confirm the results obtained with the help of the GEORADAR-EXPERT software, drilling of control wells was carried out. In the figure below you can see one of the control wells:

The certificate of confirmation of the results of the georadar survey: The results of the control drilling has confirmed the results of GPR surveys, as evidenced by the following document (it says that in areas identified by GPR loosening soil debris was found with a significant amount of wood):

The document confirming reultaty GPR survey

Translation of the document: Control drilling, carried out in places of anomalies revealed by georadar research, shows that under the construction of the floor there are low density soils. The density of the air-dry ground was 0.88-0.96 g / cm3. Investigation of soils beyond the limits of the observed anomalies has shown that the density of dry soil directly under the floor construction is 1.56 g / cm3. In addition, at the base of the floor, in places where there are anomalies, very diverse soils have been identified, consisting of construction debris mixed with a large quantity of wood.
