Foundation Leak PLEASE HELP 🙂


I am fixing up a house with 4 cracks in the foundation, a couple already fixed in the past, that leak. I need to fix them from the inside and can't afford to hire it out as this house is already costing me big $$$.

What methods do you trust? Chisel it out and put in some rubberized cement?

Early 60's poured foundation.

Problem was a huge tree close to the house I'm having removed any day now.

What on earth do you consider "big $$$"?

Usual service call for a new build wall using polyurethane is less than $500 hereabouts.

Or you can go full hack mode and get a DIY kit from Amazon (or many other places).

Re: Foundation Leak PLEASE HELP 🙂


Is urethane injection considered full hack mode, or is the DYI inexperience that makes it so?

We hired a crack injection franchise 11 years ago (poured foundation) for a home built in 1945. Still tight after 11 years and some regrading. That was for 4 or 5 cracks.

I recall 500 for the first crack, and then you get into the wheeling and dealing for the additional ones.

I use an outfit. Years ago, it was epoxy, today poly is the in thing.

DIY - well you get what you pay for....

If you need a tooth pulled, I got a pair of pliers I'll sell ya cheap. No sense wasting money on a dentist.

Structural is still epoxy, but you never know what you got, so structural stabilization is better done with reinforcement applied to the inside.

Urethane injection to stop leaks is pretty easy and not expensive. DIY, hire it out, you're probably better off hiring it out.

Thanks for the feedback. Yeah I got a quote for 2k (another about 15k) which is definitely reasonable but I wanted to DIY it since I'm already very deep into this project $

Anyone done it themselves and had success?

Fairly easy? Did you buy a kit? Did it hold up?

No kit, I sourced everything. That part took more time than the actual repair. Easy, and very repetitive. The big thing to watch out for is having hollow spots behind the crack, it will drain out in those areas. I assume it's the same with urethane. You just have to do a second injection in those areas. Make sure everything is sealed well before you start.

There are probably videos that will walk you through it.

You may be surprised at how many of those kits you'll need.

If the face crack isn't sealed first, the injection is going to ooze back out. Check whatever product you think you want to use for detailed instructions. Make sure you understand what is involved in each step. Prep has to be done right.

Also know what can go wrong and how to deal with it. Get your information first, and the decide whether you want to give it a shot. You get one shot, that's it.

15k - that's a new foundation.

Somebody saw you coming. You got big ears and buck teeth?

Re: Foundation Leak PLEASE HELP 🙂


maybe i'm missing something here, but doesn't conventional wisdom & industry standard call for the source of the leak to be repaired/remediated first?

go outside & install french drain, fix/seal cracks then worry about the inside?

I have used Simpson's Crack kit epoxy to inject a wall that we did other repair work to.

But also excavated the exterior and applied a sheet membrane to the whole wall.

Really? You got the method to make it stop raining? All the french, spanish or pekinese drains in the world do not stop ground water.

Super Seal either had a thread or weighed in on one with product and pictures. Maybe he will spot this and come to the rescue.

well silly me...

i have been under the impression, OBVIOUSLY WRONG, that the EXTERIOR of the foundation was waterproofed prior to back filling.

along with this archaic method, drains, rock, grading etc were used to help divert ground & surface water away from the foundation.

i guess i'll have to chalk it up to just more phucked up things we do in california...

PTFO....

I can't speak for the OP.

In new builds, in this state, and every one built by me, there is proper weep tile, gravel bed, membrane and sealant, backfill with slope,.

All that done, and still ground water WILL find its way to a crack and merrily drip down the inside of the foundation.

Here house with a bad foundation, 15k will not even touch it, never priced it out myself, but they say closer to 40-50k by time all said and done.

Once it's cracked, you get water.
