I had a new 24' sidewalk poured last May that was "cut" into 8 3ft each blocks. I just noticed that in 2 of the cuts there are cracks the entire width of the block.
Did the contractor mess up when he poured this by putting too much stress on the blocks by not leveling it properly?
Also, what should I do about this? I'm concerned that water will get into the cracks and cause additional damage.
Thank you!
