How do i seal this? Crack in concrete wall.

[Zebedeewesty]

My garage is made of steel reinforced concrete panels and after the galeforce winds and horizontal rain recently i've noticed a small area of damp in the rear corner next to my workbench.

Theres a hairline crack running diagonally down the panel visible from left to right in the above piccy.

How do i go about sealing this?
Can i just grind out the crack a little and fill it with a mortar mix or is there a simpler way?

Thanks in advance.

Can you get to it from the outside?

 

[Zebedeewesty]

Yep. Theres probably a crack on the outside isn't there hidden under the masonary paint?

Hydraulic cement.

Concrete is porous as a whole though, if you intend to keep the whole thing dry, it must be done from the source of the moisture.

Yep. It's always better to seal a leak from the outside if you can.

Buy a bigger workbench.....

Epoxy injection is the way to go. Do a search for Sikadur Crack Fix.

Inject with poly.
