had a new driveway poured and it has small mud
spots come up in the surface. could this be caused by the concrete co.
getting mud mixed with the concrete mix? any help would be app. thanks

YES. This is too common, and in many cases
creates a real problem. These "mud balls" that get mixed with the concrete
will dissolve with time and leave holes in the concrete. In some cases I
have seen holes large enough to cause people to trip.
Usually, these holes do not present a structural problem - the driveway
will not fail - but it looks bad and could serve as a starting point for
chipping or cracking.
In some (rare) cases, large mud balls trapped under the surface may
actually reduce a cross section of 4-5 inches to 1-2 inches. In these cases
it may cause failure of the concrete in the future, but be invisible
originally.
Depending on the extent of the problem you may have to ask your
contractor to repair his work. A good start will be to use
high-pressure washer to remove all the mud from the surface. Once that
is done you may be able to estimate the extent of the problem. In simple
cases it is possible to grout the holes with "rapid-set" grout or epoxy
grout. Just make sure the holes are clean without weak pieces. In cases
where the holes are extensive, and you suspect hidden mud-balls you may have
to remove and replace the concrete.
Where are you?
Good luck,

Thanks for the information on the mud balls in
the concrete driveway . I believe this to be caused by the concrete co. not
the finishers but the concrete co. denies this is their fault. i live in
Cartersville, GA. about 40 miles north of Atlanta, GA. I have had a computer
about a month and am just learning to use it but I sure do thank you for the
information. do you know anyone in this area that I might contact
about this problem if I need someone to look at this driveway. thanks

I am sorry, but I am not familiar with this area.
