Concrete crack
Concrete crack
(OP)
I'm trying to find out general location and shapes of cracks in the foundation due to freeze/thaw, corrosion or even carbonation.
The cracks that I'm seeing is a shallow footing with cracking all around at around 3~4" above grade. It seems like cracks/separation is happening at concrete covers.
I don't see heavy leeching of rebar corrosion. Any ideas? I've attached a sketch in an attempt to illustrate this.

Significant concrete cracking often proceeds surface staining ('rust marks') due to rebar corrosion. Break off a piece of concrete and 'see' what's under.

Get petrographic examination of the concrete done.
Also...why is foundation exposed above grade? Is this an equipment pad?
