There are superficial cracks in the new concrete staircase that appear when it has rained. Is it supposed to look like this or is something wrong? The staircase was cast last fall. The cracks are not visible when it's dry.
The concrete has dried too quickly when you were casting. This causes these small shrinkage cracks. It's not dangerous structurally, but water can find its way in and it can cause frost damage if you're unlucky.

thanks for the response, it was a company that poured the staircase for me. Is it something I should complain about? It wasn't exactly cheap...
