Concrete crack help

[sconnors]

Hoping someone here can point me in the right direction. We had quite a bit of rain last night and I've got some water on the floor. (see pictures) Noticed a rather large crack in the pad and am thinking that the water might be coming in there.

What's the best product to use to repair cracks like this?

Any input would be greatly appreciated.
Thanks
Scott

A good concrete caulk might fix that - might not. Depends on how much hydraulic pressure is behind it, if any. Sure it's not coming from under the door or wall plates?

If you have major water pressure in that crack it will push past the Sika product, eventually. You need to wait until it's dry and use a product that can hold back the pressure and won't lose it's bond.

Just curious if Sikaflex would work on this? Also is it safe to use Sikaflex between concrete and metal to fill cracks?
Any help would be greatly appreciated.

Sikaflex is meant for wider joints than a crack and it will stick to metal in my experience. However Sika will provide excellent information in that regard.

Scott,
I'd be surprised if that crack is the source of your water. Try to verify the source of the water the next time it rains. Surface water from inadequate drainage is a much more likely.
