Just moved into my new house in Ann Arbor Mi. The basement was poured in
April of 2003.

My question:

I notice the pour lines (5 inch darker diagonal line with no cracks) in four
of the basement walls. What does this mean? Possible problems?

Thanks Paul

Post a picture of the lines.

My guess would be a cold joint, though yours is almost too straight. They
are usually the result of a delay in the pour like a truck break down, pump
breakdown, etc. In a perfect world you would not have it, but as long as
the concrete was well vibrated (and yours appears to be), it should not
cause any long term harm.

On a web site and then post the url here. This isn't a .bin group.

If it was well vibrated, wouldn't you expect the line to be horizontal?

Can't do it.

It's such a bad idea to send a picture to the internet that many ISP's
routinely delete them.

The thing to do is to put them up on a web page and send us the link.

Best of luck, and let us know how it comes out!

That looks more like concrete block wall rather than concrete. Are you sure
it is poured concrete. Sure looks like the crack follows the outside grade
is this true? If so there is something else going on. Call a local
engineer to do an inspection.

Looks like a classic cold joint. If it isn't cracked or honeycombed,
don't worry about it. If you're going to finish the basement and leave
the wall exposed, there are several concrete coating products in many
colors which will cover it nicely.

Paul-

I agree with the comments & educated guesses you've received so far.

From the written description I would have guessed a cold joint but the picture
does not support the cold joint theory. The line is too straight for the
typical cold joint.

I would tend to look towards a cause that involves the forms, the exterior
grade or environmental issues (cold weather, rain, etc).

Was there foam insulation placed against the concrete (lining the form or
trench?) on the exterior (above or below grade?

Did you get a cold snap around the time of the pour?

How's your relationship with the GC or builder? Can you contact the concrete
sub for an explanation?

How about a slightly closer photo? This one show the general situation well
but a closer shot might reveal more.

If the concrete is sound in the area around the "line"; no porosity, etc it's
probably ok but it's difficult to know for sure from long distance.

regards
Bob

Hi Paul, could you please give an update on how's your basement go in the last 17 years? Is it leaky or any other problem rasied? (My new home in Ann Arbor has the same cold joint issue... just pouring the basement this Janurary)
