Voids in the subbase below concrete slabs-on-ground are a common cause of slab cracking and other issues. Ground penetrating radar (GPR) is one technique that we employ to efficiently and nondestructively detect subbase voids.

In this episode of WJE's Solving for Why series, technician Dan Wetherington demonstrates the use of GPR and discusses how we interpret and use the data collected.
