Foundation crack repair

5 posts in this topic

We have a suspected crack in the foundation wall of our basement. Leaks a bit of water into the basement when storms blow heavy rain against that side. Looking for recommendations on who to call for repairing it. It's about four feet from ground level.

How big is crack? I had one on my garage foundation that was around a 1/2 wide  in areas . I used a grinder to clean it up and just simply filled it with mortar then painted it to match. It was a pretty easy fix.

Don't know yet. It's about four feet down and I'm not able to do the work myself. Just looking for a recommendation on who I trust to fix it without gouging us.

I have experience in this as I have done it both on my own home by myself as well as others homes.

First, it is generally caused by not having enough grade in your yard to take the water away that is shed by the roof during a rain. If you do everything else and don't fix this then problems will still occur. 

Is the basement finished?

Can you see where the water is coming in?

is any water coming through cracks in the floor or only the sidewall?

Is the wall bowed in towards the interior where the cracks are? This is usually the case.

Do you have gutters on the house and are they kept clean with enough extension away from the house to get the rain water clear from the foundation?

Is the wall block, stone or poured concrete (Most likely block)

 

Here is my recommendation if the wall is bowed in towards the interior.

I would have the utilities located and have someone dig around the foundation down to the footings and install a drain tile around the perimeter of the house below the footing level. Then punch through and add a tile around the inside of the footing which requires cutting a trench in the basement floor and tie the two together. At some location drop in a sump basket and sump pump and drop the tiles into that. If this part is done already the job becomes much simpler. Add pea rock over the tile and then pour new concrete in the basement.

To fix the bowed walls in the basement if you have them you will want to add treated or steel posts that are notched into the concrete floor and attached to the floor joists and jack them back to straight. This will prevent them from buckling in the future. On the outside I would clean and seal the cracks and add a heavy poly barrier on the outside that goes from above ground level to the foundation and then add pea rock over the tile and backfill. Regrade the area and you will be fixed.

 

There are companies that use plates outside and inside with threaded rod to brace the foundation without excavation and it is cheaper but doesn't fix the issues that cause it. 

In the end you need to get water off your roof and away from the foundation and make sure any that does get to the foundation has somewhere to go.

Aaaah below grade...silly me. Pf has a lot of great ideas there. My old house leaked a we ended up putting a sump pump and tile in. It all comes down how bad the rest of the foundation is like Pf stated. I do know a lot of different stucco crews in the metro, if I recall I remember one guy telling me that they were putting foam on a foundation under grade for the same reason. Kind of a cheaper way out if your foundation isn't all that bad. I guess start calling and getting quotes and ideas. I can also ask around if you like.

    •   No expert here either but I've talked to a couple.    Would your new, expanded slab be conducive to making the addition another zone or zones?  You could maybe run that expansion off different lines from the manifold above the slab so you don't have to route and pour over seams.   Definitely insulate below with GOOD insulation.  As mentioned, heat doesn't really rise the way we think it does; it moves to the cold and the earth will soak it up.   Heating your loop would be cheapest with a natural gas fired boiler, propane second.  Geothermal is expensive to put in so your payback on a new system is long.  Air source heat pumps are great until it gets really cold.  In the end, radiant in floor is the most efficient way to heat, but yes, it's slow to respond.  But if your toes are warm, you will be too.
    • I appreciate the response, I take nothing personally and didn't mean to be snippy in my reply. There are a lot of great comments on here and I will keep you posted on what I decide. Thanks again. 
    • Ice is quickly thinning on those northern lakes that still have ice with dangerous conditions on most lakes. The Wisconsin River is now open even in its northern stretches, but ice chucks can be seen melting along the river's edge. The lower Wisconsin River has finally dropped to near normal levels. Some walleye and brown trout are being caught on the Menominee River both trolling and angling from shore. Low water and cool water temperatures slowed the walleye run so far on the Oconto River. Anglers along the Wolf River have been starting to catch walleyes. A few sturgeon have been seen along the Wolf River, but warmer temperatures are needed for the sturgeon to start their annual spring spawning run. Walleye and sauger action on the Wisconsin River and Lake Wisconsin is slowly picking up.The steelhead season opened on the lower stretch of the Brule River last weekend and anglers reported good successPhoto Credit: DNRSpring steelhead fishing opened last Saturday for the lower stretch of the Brule River and there were lots of fishermen and fisherwomen on the river many who had a successful opener. .
    • I apologize if that came out wrong. The idea might very well be the best route to go. It's just that over the past 25 years or so I have seen many attempts to save a dollar that cost a buck and a half to do lol.    Here are my two cents. If you have a slab and you want to pour on top of it while keeping the same footprint that sounds pretty doable and could probably save some money if you don't have to change drain lines, run water, heat runs, electrical etc into the slab.   If you intend to tie into the existing slab and run zones of pex across the joint and have the new and old floors end up at the same elevation it still can be done. Some contractors will not want to mess with tying into and raising the elevation of the slabs and will prefer to start from scratch especially if you as the homeowner want them to warranty the finished product.  The critical thing would be to use enough rebar drilled into the old slab and have enough compaction and sufficient footings to make sure the slabs stay where they are without settling. That would make all kinds of problems with the pex.    Hopefully that response came across better.
    • It'll be interesting to see if the team plays a little harder in front of a different goalie. 
    • Hawg, I'm with you on this one !
    • Check and see if you have a video output on you device. You may be able to record to a digital device.
    • Just use plain old spray paint in a can. I've done it many many times and seems to stick really nice. Nothing special either I can't even tell you the brand because I have no clue. But as mentioned doing 2-3 light coats helps.
    • no expert here, but heat doesn't rise. heat radiates in the direction of least resistance (R value). warm air or water rises because it is less dense than colder air or water.  If you don't insulate you will be heating the ground under your cabin and the earth is a very large heat sink $$$. get some info from an expert in the radiant field as far as tube diameter, spacing, water temp, manifolds, length of runs, and so on. it varies on amount of windows (solar) ceiling height and room type (bed, bath, living area,  storage etc.). once you pour over the tubing you get to live with it. I did my own Home 15 years ago and got some good advise (wish I would have taken it all)
