Unfinished basement water leak
Hi all, looking to see if anyone has seen this in an unfinished basement. A couple of days ago, I noticed that some water leaked into the unfinished basement and pooled next to the furnace. Upon inspection, I found two wooden planks that are embedded in the cement behind the laundry washer. It seems the source of the water was from that spot but I cannot be certain. The next day everything looked dry and there didn't seem to be any water stains. It's the first time seeing the wood and this is the first time a water leak has happened since moving in last winter. Are the wooden planks normal in a build and does it have any purpose? I hope it's not to plug some hole in the concrete.
