Often,
due to Texas soil conditions, a structural engineer will mandate
that piers be drilled into the ground and filled with concrete
usually reinforced with heavy steel. These concrete piers will vary in
diameter and in depth depending on the engineer’s plan. The
standard
concrete pier is 1 foot in diameter and can vary from 8 ft to 18 ft
in depth. A specialized heavy-duty drilling machine is required to
drill these piers.
