I don't know the slab depth. What should I do?


If you don't know the slab depth, you have two options:

1) Find the building plans to determine exact depth.

2) Use a smaller diameter drill bit and drill through concrete to get an exact depth.

It important to know the exact depth because the depth that the "sensor" must be at is part of the ASTM F2170-11 standard.
