Concrete slab dip

[Dave]

We just had a 40'x60' 4" thick slab poured for a steel shop building. In 3
or 4 places the slab has 'ponds' about 6' across and 1/4"-1/2" deep.
Honestly they are not overly noticable until you wash the floor and the
water ponds up. Then 1/2" of standing water is quite noticable.

My question is: on a 2400sqft slab, is 3 or 4 ponds of that depth normal?
What 'school grade' would that rate? A? B? C? D? F?

Get out your written contract and read the specifications. They may
not have met spec and owe you some money.

Otherwise, put a roof on it and don't use so much water when you mop,
so you will never know that its not level.

I agree with Bilko. Drilling 1/2" holes will do it. Use 5/8" if there's a
chance of debris. You might hit reinforcing but most mesh has wire size
about 12 gauge and not too obstructive.
