foundation crack

Hi guys, so I have a crack foundation I want to use the flexible polyurethane grout injection kit and fix it from the inside.

My question is would it be OK to use it while is raining or should I wait for the rain to stop, it will rain for the next couple of days and if it rains hard it leaks.

I am thinking that if water is coming thru while I am applying the polyurethane it will not work properly what do u think.

Any help would be appreciated

Waterproofing from the inside will fail sooner or later. Seal it from the outside with the proper membrane & you'll live happily ever after. It requires some digging but it's worth it.

Yeah i might have to, i did it once but I didn't want to dig this time, I have a back problem.

If it fails I will have to dig and do it from outside, they say this stuff is really good and will last.

But what about my question, I put the plastic ports today, I will put the mortar tomorrow and then injected with the polyurethane grout, hope it doesn't rain tonight or tomorrow

If you want to take a chance, go head. It might work. You won't damage anything.

Have you considered hydraulic cement? A little moisture should not effect installation, but it is honestly best to repair from the exterior

seeing as you've got to flush out the crack in advance of injection, why wait ? we do that work professionally &, despite what others may think/post, its an accepted waterproofing method - even spec'd by state/fed dot's,,, i like hydrophyllic rather than hydrophobic for cracks leaking water,,, if it helps, i charge $600 for 8' vertical cracks - each just to show up w/material & seal 1 crack's min charge $ 800 why do i charge that ? the largest advertising wtrproofing co in town charges $ 1,200


ps - hydraulic's not a suitable material for this purpose nor is it as permanent as the method you've selected
