Attached Garage Wall Cracks
 
I have an attached garage with a concrete slab floor and concrete walls. There is a large horizontal crack about 3 1/2" up from the floor on the inside of the outer wall. What is the best way to repair this crack? Since it would be difficult to get concrete mix into the crack, is there a caulk of some sort that could be used?

Yes. Go to Sherwin Williams and ask for their "Elastomeric caulk". :thumbsup:

also do some research on why the crack is there. epoxy injection, is another option for structural damage.

Concrete crack repair 101
 
Very common problem, If the crack is very small and mortor could not easily penetrate you can enlarge the crack. This is standard procedure and will aid in a strong bond to the wall.

If the wall is painted them you must chip off the paint or the mortor will not stick.

There is a excellent product called "top and bond" that will do a great job, it sticks to anything except paint. If you want to make it even stickyer you can buy additional bonding additives.

Read your instructions and fallow them and no more crack:thumbsup:

What is behind the garage wall? - Is it soil?

Usually, a horizontal wall is a structural issue and a classic sign the wall has slightly failed.

The garage is attached to the house and on the unattached sides, the wall comes up about 28 inches from the concrete slab. I do not know how far it goes into the ground but I suspect not much further than the bottom of the slab.

The age of the house and garage is 36 years.
