Subgrade Condition Assessments

When a severe thunderstorm or a tropical cyclone hits an area, it typically leaves great damage behind. Buildings are usually flooded by the amount of rain that is the aftermath of storms. Flooding could leave structural issues in building foundations.

In the following example we will see the result of a residential home inspection, specifically focused on subgrade issues (See Picture 1.).

GPR method was used to create a virtual ground condition map (See Picture 2.) to learn how much the area was affected by the devastation.

At the end, the result of GPR the map was combined with the LiDAR documentation for better visualization purposes (See Picture 3.).

Structural supports and grade beam locations were also detected with GPR thus the beam layout was able to determine (See BLUE area on Pic.3).
