Ground Penetrating Radar Voids
|
Data was taken over a concrete slab with wire-mesh reinforcement.
This data is clear, revealing no void.
|
|
 |
The
right side of this data reveals a void 6" from the surface.
There is a high level of reinforcement above the void. The void is indicated by the horiztonal black-white-black presence. |
|
This data shows the early stages of a void.
In this case, the void was beginning to occur about 6 feet from the exterior wall and proceeding towards the foundation.
The sub-grade material was not properly compacted, causing the void. |

 |
Data taken on a pool deck reveals a void imediately below the concrete slab. The rebar is on 18" centers. |

The difference between grouted cells and hollow cells in a masonry block wall:
The grouted cells have a rebar about 4 inches from the surface and a grey contrast throughout the cell.
The hollow cells show a black-white-black reaction near the top of the profile. |
