I have an old 1910 house in Portland OR and the foundation wall is starting to crumble away. I need to recoat it, i had a professional come and give me an estimate but i am wondering if this is something that can be done easily by me.
What are good resources or suggestions you might have. I need to keep moisture away too. Should i just hire the professional and not get involved if i have never done this before. The house is not big, but i could see this being a lot of work.
Thanks
My driveway is doing the same thing. Never saw this kind of thing before. My house is 4 years old...
moisture is the enemy, for the driveway pressure wash let dry for days, coat with thompsons water seal, literally dump and broom on. very heavy let it soak in. it will darken the concrete but stop water infiltration. recoat using much less thompsons oil based every few years.
hows the drainage around the home? gutter clogged spilling over? downspout water well away from home, hows the grade, towards home:(
Coating of the interior of the foundation will do NOTHING but trap more moisture:( calling more spalling...

Nothing about working with cement is "easy". When concrete/cement finally finishes "curing", it crumbles into dust.
In 1910 shortcuts could have been taken, dirty (or even beach) sand, dirty/dusty rock. You may be seeing the end of life of your foundation.
You need an evaluation/estimate by a competent professional. -----

So you suggest letting a pro team do this. I think i might agree. What should be done to ensure life for the foundation? it is a comong problem in oregon as they did use dirty river rocks and sand which is the problem. Is a waterproof coat and new skim coat enough to keep things in place?

basically i am asking what questions should i ask to ensure the best result.
The first thing you need to realize this could be a major problem. The foundation is the main structural support for your house. If it is grumbling I don't think recoating it is the answer there is a problem with the concrete itself. The concrete may have been mixed with sand from a beach the salt in the sand can cause the concrete to deteriorate it dose take quiet a few years . Either way you need to consult a contractor or an engineer. I would get more than one opinion / estimate. The worst scenario is the house has to be jacked up an a new foundation put under it. It's hard to say what's going without seeing it. But it's not something an average homeowner should tackle. If you foundation is actually crumbling you need to do something about it.
