calling all concrete pros, I need your help !

Hi,

I had a concrete slab put in the backyard a couple years ago.
Last summer I notice some serious erosion around the sides (see pictures).

To make the problem worse I now have a mouse infestation living under the slab.
What is the recommended, easiest way to fix this problem ?

Any help or ideas for a beginner are appreciated.

The bottom should never be exposed, water will erode the substrate and the concrete will eventually sink. Move the rock, bring in some clay and pack it against the edge and underneath, bring it up to that middle/form line. Establish positive drainage away from the slab, then you can finish however you want.

This is great advise thank you.
is there a specific type of clay that I should be using ?
Again I have never done anything with concrete or clay.

I'll be taking your advise and to finish I will add bring up the grass line with a gentle slope just
above the middle form line.

Clay soil, the kind that you squeeze into a ball and doesn't fall apart. My yard had lots prior to bringing in planting mix, a nightmare to garden with but in your application, it's perfect.

Thank you for the advise.
Sounds easier then mixing concrete so I will definitely try out your idea.
