Concrete repair help

Hello everyone,

I have a small area where my garage slab meets the garage foundation that is in need of concrete repair.

I know I'll have to make a small form for the area under the brick.

I'm most concerned with the area under the slab as it seems to be carved out about 4 inches deep and about 6 inches wide . I'm worried if I drive my car over this, the concrete will snap off.

What is the best course of action for this? and what kind of concrete repair should I use?

Is it advisable to break the corner of the slab myself and repour the small area or can I just mix up some concrete and try to push it underneath the slab (or perhaps use a funnel and a bag like how a baker uses icing?)

I'm not completely inept but I have minimal experience working with concrete.

Thanks.

I have the same issue on my garage where the concrete meets the assualt, I was planning on getting asphalt mix and stuffing it in there good.

In a couple years I'll get the entire driveway replaced and get it fixed up good, seeing there is a change of surface material i think a lot of us have the same issue in the same place.

How old is your driveway, are you worried more about the concrete or the cavity caused by water in the concrete asphalt gap?

We both need to address the issue as it will only get worse if left unattended too long.

I'm more concerned with the exposed area under the slab. The parts where the asphalt has pulled away from the slab should be easy to deal with. Home Depot sells foam backer to fill the gap and then a goop is applied

Don't listen to the other crap. This is the solution. You need something that EXPANDS not just packs in.
