Hi all, I'm new to the forum and recently my concrete basement floor has been going through significant hairline cracking since I purchased the home six months ago. This is an older home, built in 1931. Small holes in the floor have also sprouted up. We've had a lot of rain lately and I am aware of moisture issues within the walls.

I have attached pictures of the more peculiar situations. The second photo is a patter that has developed, where divots appear in a line, there is a few lines of these throughout the basement. Are these holes and divots something to be concerned about? And what could be causing this?

Thanks!!

I wound be very interested to see what is going on under the slab.

How is the grading and gutter situation?

Any perimeter, weeping tile, drains?

The gutters were cleaned once I purchased the house and guards were put on, was the first thing I did since they were packed full of leaves. All the gutters attached to the main structure flow into a drain instead of downspouts.

The grading is an issue on one side of my house, in certain spots the concrete walkway is tilt towards the foundation causing excessive water buildup during heavy downpour. I've been considering getting a concrete specialist come out to see if mudjacking would fix that.

Cheaper to tear it out and replace, rather than mud jack.

Looks to me like you may have a significant water infiltration issue beneath the basement floor. You mentioned water in the walls which is likely be the source of water under the floor. I always recommend tracing and correcting water issues before doing any other remedial work.

Mudjacking might be an option on the walkway, but not until you get the water routed away from the foundation.
