Need help; sealing foundation crack:
 

Anyone know what I should use to seal this crack along the base of the foundation of this house? This is on the side where a sidewalk runs along and the sun does not shine. Is there a particular product and/or brand that anyone likes for this job? I'm assuming there is a tube of caulk-type stuff that will seal it and hold up to extreme weather variations. (It's in Minnesota). TIA as always. :cool:

Waterplug hydraulic cement

Thanks Vinny!

Dennis its a dry power that hardens immediately. You can put it on a crack that has water puring out of it and it will seal it right up.
Now that i look at it closer, I think you might want to use something flexible. You are talking about the the joint at the sidewalk/wall ?

Yes, the crack between the sidewalk and wall. I was thinking something that comes in a tube and goes in a caulk gun.

What in the world are you doing in MN??? Not home yet?

Hows the pup doing?

Ive used a caulking made by a company NP it think its called DU concrete caulking comes in an orange and black tube I know you can only get it in a builders supply ,its not the kind of stuff a home center carries.

I use a lot of PL Products ployurethane caulks in my work and I am impressed with their strength. Not water clean up, so they can be a bear to use. They make a gray for concrete. About 4 bucks a tube.

They just fixed some cracks in my new pool. They set small ports into the crack in epoxy, 8 hours later they pumped high pressure epoxy into the ports.

The area where the crack is at is going to move alot so I would recommend against anything that is not flexible. We have a concrete pond built in 1926 when the house was built. Had a number of cracks so it wouldn't hold water. I went to Lowes and got concrete caulk. Comes in light gray and dark gray. Has held up well to all the shifting of the concrete from summer to winter. That is what I would recommend.

Is this a cosmetic repair, or are you trying to solve a problem? If cosmetic, just use a flexible grey caulk.

Red- Why did the new pool crack?

James, interesting product. Since I do some epoxy repairs and restorations, I can maybe use something like that or make up something similar in the shop. Thanks.

Sikaflex is designed for this.

Thanks, guys. I've been away from the computer all day so I'm just seeing this. I'm not sure if the crack is causing any real problems, (not my house), but it just seems logical that you would not want water going in there.

I'll check with a builders supply place in town here for the best nuclear strength flexible caulk and apply it.

Joe, I've been gone a while, huh? I'm in MN. now hanging with family and friends and I've been fortunate enough to get roped into some work/$$. Not sure exactly when I'll be home.

Sikaflex would work.
I tend to use mostly Tremco products. Tremco Dymonic would work fine.

Use the best Urethane Sealant you can find. Try to find a local supply house which specializes in caulk. Not sure if HD or Lowe's carry a quality urethane. Make sure the crack is clean and very dry. Do a google search on tips for applying urethane sealants. Its extremely sticky when touched with an unlubed finger.

When the crack fixers came, they dug into the cracks and found them to be mostly surface cracks, really nothing to worry about. They filled them with expoxy, so they would get paid...

In a 6 inch thick concrete structure, a crack every 10 feet should be expected. Usually, a system is put in place to allow cracks in defined locations, then resealed.

In my case, the crack split one of the flagstones in the coping, and with water coming though, it was thought it might go all the way through the gunite, so it was fixed.

Better now, during construction, than later. Of course, it delayed the construction another week!
