Cracks in House foundation


Hello All

I noticed when walking around my house perimeter and inspecting the concrete base, that there are two problems

1. There are cracks on each side on the house (see pictures)
2. With one of the cracks, it seems the ants are coming in and out. I have placed one trap there right now, and ton more are coming out. (see first picture and left side)

I am going to leave traps there for a few days, however, how i do i permanently fix this, seal the crack and get rid of the ants "inside". Would it be safe to assume there are a ton more in the concrete? or that my concrete base is bad.

Sorry about the pictures, but the pictures needs to be rotated 90 degrees to the left.

If your ant trap isn't a bait type, swap it out. The ants will take the bait back to the nest and kill the rest of the colony. It's not instant but it does work.

Does that crack extend further down into the basement?

its the bait type, the whole carry back deal.

I did not see the crack on the inside of the house in the basement. but then again, the top half of the wall is covered with insulation.

Might want to take a look at the corner from the inside and post some pics. Could be indicative of a problem especially since it's a corner. Might be nothing.

How old is the house? Do you have water problems in the basement or a sump pump that runs when it rains?

It might be easier to pull the insulation close to the floor first to see if the crack runs all the way down the wall.

No sump pump, we are above water level i believe, so no water issues. The house is 9 years old (built 2004) and there was one crack that was filled in with yellow foam stuff, just before we moved in (we moved in Nov 2012). I will take a picture to show. But its no where near the pictures that i have shared.

So over winter, we didnt notice anything, then summer hits and all of a sudden we have ants and ants galore, which then leads me to a walkaround and i notice the two cracks! And one with ants coming in and out. So, i am working towards getting rid of the ants, using bait traps and spray. But next issue is crack itself.

In the basement, the insulation is from the middle of the wall to the top. The bottom half of the concrete wall is exposed and there seems to be no crack there. I am going to do a better inspection over the weekend and post some pictures.

Thank you for everyone's help so far. its really appreciated. i will hopefully provide more answers shortly.

trust me, ' above water level ' isn't the same thing as ' above normal water table ',,, if you have a basement, you're right AT the water level

You need to examine what is behind there. Ants like to nest in wet, rotted wood. A downspout, a crack, and a lot of ants, are an ugly coincidence.

So, i remove the vapor barrier and take a look behind the pink stuff and guess what, no exposure concrete! One corner of the house has drywall behind the pink stuff? what is up with that.



nut there is no cracks, no water inside, take a look at the pictures.

could i just fill the crack using the appropriate quikrite product?

you sure its drywall OR the backside of some exterior siding mtl ? if you removed the insulation, you should've seen wood or metal studs,,, IF you're sure you're behind the crack ( same elevation ) & you don't actually SEE the crack from inside, i wouldn't worry about it,,, otoh, ants rarely nest in conc from what i hear

quikrete, surecrete, dynamitecrete, gawda'mighty crete,,, if its a brand name you know AND you know enough to pick the right material, use it

Sure does look like drywall. Maybe it's hiding something. I love the "notches" in the rim joists.
