Fill Wall To Floor Slab Gap

[GlennSullivan]

I'm looking to fill a rather wide gap - 3/4" to 1" - between a concrete wall and floor slab in my garage before recoating the floor as I want to extend the new floor slab coating to the wall and to install a vinyl cove base when done.

I've looked at several different products (self leveling, trowel in, etc) and am confused.

Anyone got experience in this area??

1" is wide. Use a trowel grade epoxy patch.

Before we painted our floor I filled the gap with expanding foam and used a wirewheel to take off the excess. Worked beyond my wildest dreams but would depend on the type of coating you intend to use.

Glenn, I would use SikaFlex SL available in giant tubes from home depot. I used this around my basement floor expansion joints after epoxy first. Works good. You want to fill the gaps up to about 1/2" from the top or so to save on the amount of Sika to use. Sureshot has a clever idea there with expanding foam. Others use various foam backing rods. If you want to epoxy over the joint, I don't recommend this, but if you insist, use a good flexible product like Scotty's. Problem is epoxy may well crack sometime over the joints if you do that. - Paul

Gentlemen,
Like Glenn I am concerned about preparing the perimeter expansion joints. But I am also concerned about how to treat the joint under the garage door. I live in Michigan and the outside slab can rise an amazing amount in the winter when the ground freezes so the filler material must be able to handle the movement. Conventional wisdom is to leave it alone. However I frequently move project cars in and out on dollys and the steel wheels ALWAYS hang up on the crack. Assuming that I accept the fact that the outside slab will rise in the winter, Is there any product that I can use to fill the joint that will be hard enough to handle the dolly wheels in the summer and still be flexible in the and winter???

Best bet Finkster is the Sikaflex SL. It moves and expands/contracts better than anything else I've run across. - Paul

Never mind. I just saw the date on the original post. May be too late...

Here's an interesting approach Red Leader took in the 1950's Craftsman Garage

Using wood like Redleader did is definitely a different take. While it would probably hold up to the wear and tear, it would not be able to expand or contract as much as the concrete might want those joints to move. So over time, I wouldn't be surprised if those either pop out or if a gap happens along the edges of them. Look great though! His whole thread is pretty amazing! - Paul
