Is something wrong beneath BISD's new stadium?

There shouldn't be an issue underneath the stands because they poured under-reams like 30 ft. deep. This should prevent the concrete from shifting.

Cool......

I thought you needed to do soil samples to know how deep to make the under-reams.....

Anyone know?

As long a the pier is deep enough to reach soil that has no moisture variation, it doesn't matter what type soil is on top.  I assume at 30 feet that the soil never gets dry in that area, so no shrinkage,  which is what causes movement.
