Sealing a large basement crack.
HI there. I know that this is a reaccuring question but i would appreciate some help with my basement problem.
I have found a river flowing from under my drywall and removed it to find a massive crack, well not much of a crack but disintegrating concrete...there are crack leading off this one in the picture. someone in all there wisdom tried filling the cracks with expanding window foam?
How would i go about sealing these up...i could fill it with hydraulic cement, but would that just stop it right at the surface?
how would i fill the smaller cracks?
hope you guys can help me out here.
