Question from Newbie re: break in corner of poured concrete foundation

[Lisa Masciantonio]

Hi folks,

First, thanks to all in advance for taking the time to respond to this question. I am brand new to the forum, and hope that I am posting this question in the right area. Anyway, here it goes...

We own a two-story, 25-year old saltbox colonial on a poured concrete foundation (with full basement). Last fall, a fairly large 'chunk' of concrete fell off of the rear corner of our foundation (looked lie a pie wedge, with the largest area being approximately 4-5 inches long, 2-3 inches deep). I found it laying on the ground while gardening. Fast forward several few months, and it appears that the same thing is now occurring in the opposite corner of the house, to the front of the property (though, not quite as big as the other break). So, I had a 'moment,' then decided to call a structural engineer to have a look. He tells me this is not a structural issue and not to be concerned. Great, but here's the but...I continue to see evidence of some further breakage in one of the areas.

Not sure what, if anything, to do at this juncture. If I had 50K kicking around to fix foundation issues, no big deal. Unfortunately, that is not the case. I know in talking to other contractors who have been to the house, several building shortcuts were taken (always nice to find that out after purchasing a home). I am hoping the foundation was not one of those shortcuts.

Looking to the experts on the forum for advice and possible solutions.

Again, thanks in advance!

You already had an engineer look at it, so thats good. Concrete edges, particularly at corners, can be weak. It shouldn't be a big deal for a foundation contractor to chip out and patch those areas. And have him sound out the other corners while he is there.

[Lisa Masciantonio]

Thank you very much, Robert. My concern was/is that nothing is now 'holding up' that edge of the house (since the break is at the very top of the foundation). I'm just wondering how much of these corners can break away before it becomes a real structural issue???

I want to do what is right for the house, and also what is honest. We do want to sell the house eventually and I do not want someone else to inherit a problem.

Thanks, again.

Like Robert said, have a reputable Foundation Contractor make needed repairs and inspect the integrity of the overall foundation system.

[Lisa Masciantonio]

Thanks to both of you. Can you recommend a resource(s) for me to locate an honest, reputable foundation repair contractor? We are located in Massachusetts. Short of looking for one in the yellow pages, I would not know where to begin.

I am doing something I said I would not.
You have to be a bit more descriptive.
Any foundation cracks around that area?
Any cracks period?
Downspouts at those corners?
Get back to me if you are answering yes to any of these questions.
For your downspouts- Run extensions 8 to 10 feet away from the home.
I have seen and repaired what you are describing.
Pie shaped wedged that have fallen away from foundations.

It can be settlement displacing itself over a weakened parts of the foundation. The exterior or outer corners.
The displacement of the home is focused over the weakest part of the foundation, the outside corner that has or is not perfectly leveled when the pour was completed.
Make sure your land slopes away from the foundation. They say 1" inch for 6 ' of run I say more. I like 2" inches for ten feet of run.
I bet you have your downspouts at the corners.

[Lisa Masciantonio]

Hi Robert,

Thanks for taking the time to reply to my post. To answer your questions:

Any foundation cracks around that area? Not in that area.
Any cracks period? Yes, a 1/4 inch vertical crack on the opposite side of the house.
Downspouts at those corners? Yes, a downspout in two corners, with a five-foot extension. One corner with a break does not have a downspout located there. For a period of years (15 +) there were no gutters or downspouts on the house. We installed them after we moved in (10 yrs ago).

There is also concrete that is broken away in two other corners of the foundation (one is pie shaped, the other is not). Only one corner of the house has no evidence of breakage or damage.

Get back to me if you are answering yes to any of these questions.
For your downspouts- Run extensions 8 to 10 feet away from the home.

Hi Robert,

This reply may post in duplicate, so I apologize if that happens. Thank you very much for responding to my post. Responses to your questions are below:

Any foundation cracks around that area? Not in the area of the largest break.
Any cracks period? Yes, one. A 1/4 inch vertical crack in the foundation wall, opposite side of the house.
Downspouts at those corners? Yes, at two of the corners, with a five-foot extension. (I don't know if this is important, but for 15+ years, the home had no gutters. Gutters were installed shortly after we moved in to the home, 10 years ago.) There are three corners in total with a concrete break. Two are at the very corner of the foundation. One is not quite on the corner, but close to, along the top of the foundation edge. The fourth edge does not appear to have any breaks or cracks. I see no other evidence of concrete breaks or spalling. Some efflorescense (sp?) in the basement.

I'm also fairly certain the property is not properly graded. The entire lot is extremely flat. Admittedly, we were young and a bit naive when we purchased the property. We had no indication at the time that anything may be wrong. We trusted what we were told.

[ROBERT V. YOUNG]

Effervescence is the tell tale sign of a wet foundation and more prone to breaking.
Even if your downspouts are 5 feet away with the lot graded reversed pitched you are asking for a costly repair.
Call a plumber or seasoned home inspector that can video your french drain.
Its time to get the kids, kids friends, your friends or a company to grade your land properly.
They say 1" in six'. !" inch rise for 6' feet of run but its a bit more complicated than that.

It depends on where your home in situated on the land.
You have all the indications of a damp foundation.

They have french drains and basement water problems?

Sometimes french drains that are block cause damp basement and even water infiltration. When there is effervescence you know its time to act..
Here is an inspect last month from land that was sloped in reverse.
I have more photos.
All the downspout and the lands grading caused this problem. Actually no maintenance was the cause.
Now you know why I do not like posting answers to questions that have so many possibility's.

I will go back and remove that post.

[ROBERT V. YOUNG]

The french drain will tell you a lot about the health of the system Mr.O'connor. ( if you can access it and if there is one ) I have never seen a home without a water drainage or movement system.
I have done this for 12 plus years now. I use to charge $250. dollars. You get a VHS back then and now a DVD or CD.
I do not know what to charge and have yet to implemented it into my inspection packages..
Hard to understand a client on the message board and no photos for hypothesis.
