How to patch holes in outdoor concrete area?

bornToDIY

Hi

I have some holes in concrete near an old outdoor gas heating unit - please see photo.  This area is exposed to rain.

Some of the broken concrete might have been on a gradient to help with rain run-off - not sure.

I want to patch the holes to stop rain from getting in under the unit (and under the house).

What should I use to do it and how?

Thanks

Where exactly are the holes @bornToDIY? Are they under the rubble on the left-hand side? If so, can you remove it so our members can get a better look at the area in need of repair?

I suspect you'll need to use a combination of Concremate for the bigger missing sections and then Sikaflex 11FC to fill in the gap between the heating unit and the concrete. Please reference the manufacturer guidelines for the unit before sealing the bottom edge to the ground. there might be a gap left for safety reasons.
