Cracks appearing in Concrete
It's not load-bearing, just the narrow corner trim at one end of my concrete pre-fab garage (one of those with a 'brick' pattern moulded into it)
I reckon moisture has got in over the years and caused the metal inside to corrode, expand then crack the concrete.
My question is how best to stop them continuing and getting bigger... I can keep water out to a degree by mortaring-up the cracks, but wouldn't it be best to inject some kind of waterproof adhesive first? What about Gorilla Glue... that is powerful, expands like expanding foam, and is waterproof too?
