What are these plugs in the concrete foundation?

Saw these in a couple places in my basement. What are they?

Gotcha. Guess the previous owner did a crap job! They leaking now. Guess I gotta find a contractor to do it the right way from the outside.

That sucks. The spring melt is what's causing your issue. Get a quote from Aquatech Waterproofing. I went with them and things are good.

that may not be necessary; do you have the info on who did the job in first place? usually there is a warranty on those.

However, from my understanding, there are usually a few more holes that are drilled up the wall to inject it across height of foundation.

You could seek out other epoxy injection companies to fix /do it right.

Exterior waterproofing could be tens of thousands.

Unfortunately ... this was at least 6 years ago. We bought the place in 2016 ... previous owner did not advise. Now ... mission impossible to find them and see who did the job. No trail was left in any documentation that I was left with when the ownership changed hands.

Basement flooding can cost more than the cost of exterior waterproofing. Not to mention the peace of mind that you get when you don't have to worry about your house leaking, messing up your stuff and the additional risks of mould, etc.

I reached out to a few contractors over the last couple of weeks ...

One wall has two leaks ... so to cover off that area .. we're looking at about 16' in length. The other wall has one leak with the gas line closeby ... that section is about 6' in length. Both needs to go down to the bottom of the foundation (about 6.5').

Excavation from the outside ... so looking at 16' L x 2' W x 6.5' D and a second one 6' L x 2' W x 6.5' D ...

Got quotes ranging from $7500+taxes to $11,000+taxes.

Do you have water gathering outside your house? If your grading isn't good, improving it to flow water away from your house is an easy fix you can DIY.

My unfinished basement has one too. It was corner of basement window that cracked (I looked from outside). It was leaked after 1st winter, builder sent people to fix it in couple weeks, he pumped vertical excessive adhesive oozing out to block the leak. It worked, it was 21 years ago. Every snow thaw, I check by touching the area to make sure it is not wet.

BTW I just went to basement checking that spot and around, including cold room.

We also had it, new build 8 yrs ago. Builder had guy do injection, nothing since.

Now, whether trying to inject after a first repair has been done, may change things. And not as proper a fix as what you're being quoted, but worked for us.

You might try reaching out to your former real estate lawyer and ask them if they can provide any contact information. They may know the other parties former real estate agent, lawyer or direct contact info.

Those prices are in line with what we paid about 10 years ago. I'd go with one or these contractors.

Don't bother with injection, it's a temporary fix and water will eventually find its way in.

No water pooling on either side. But each massive rain storm ... water pools in basement. I have the tendency each winter to shovel all around the foundation ... both sides of the house as well as my backyard to minimize the buildup of snow along the house ... that way when it melts there is less water.

However, the side where I have 2 leaks ... my stupid neighbour has ladders, a dead lawnmower, pieces of old plywood, their recycling bins, a wooden barrel, plus a crap load of other things ... I own 90% of the space between the two of us as per the property line ... gonna wait when the contractor does my job and have him talk to the neighbours to move the crap (the space between the houses is about 4 feet)

I have one side of my basement wall leaking a very small amount of water. Just an inch or two of the floor near the wall got wet that too not throughout the wall. It first happened when in Jan the temp rose above zero for a day or two and then now in spring at another location. I am not sure if this was moisture trapped in the vapor barrier behind the drywall that leaked or it is outside snow melt which has made the way in .
By your comment above, are you suggesting that these small leaks are better left alone and better manage outside water flow away from the wall ?
If the wall is cracked etc? is epoxy filling or outside waterproofing is really needed for small leaks? Will leaving those untreated make those worse or compromise foundation structural integrity over long period? What do you guys think

I agree, those are reasonable quotes. It's better to spend the money and get the actual problem investigated and fixed for a massive investment that is your Home.

What I'm saying is that fastest and easiest thing you can do is to keep water away from your house/foundation. Running drains far away and making sure the ground is well sloped away from the house can do a lot. Of course if your area is low and constantly damp, then you would need to do more.

OP: it appears that the injection was done only toward the bottom of a crack and "only" caulked above a certain point and caulking is insufficient. Where is the leak?

There doesn't need to be water pooling against the house for there to be a problem. Clearly, if you have a leak, there is water in the soil and it is under pressure from the weight of the water above it in the soil. Grading the soil away from the house and ensuring that downspouts and eavestroughs are clear and direct water away from the foundation can help reduce leaking.
