A part of the billboard construction process – whether the sign has wooden poles or metal ones – is to dig a hole in the earth that meets the required engineering standards to hold the sign up.

In this episode of the Billboard Mastery podcast we’re going to discuss what happens when you hit the unexpected, and how to mitigate the cost and make the right decision.
