Suggestions on my concrete floor

[Luci Fur]

I have a 28x26 shop that has two expansion joists (forgive my ignorance if that is the incorrect term)on the concrete floor.

Here is my issue they are not flush with the floor, maybe a 1/2" lower than the concrete. Its a pain when im rolling around my cab on the cart or anything with smaller casters. Not to mention the dirt that gets in there.

Is it possible to mix up some fast patch or something and use it to fill the gap?

Here is a couple of pics

Any ideas to fix this issue would be appreciated,
thanks.

now dont quote me on this haha but wouldn't you want something flexible to fill that in?

What would you suggest? Kinda makes sense if its an expansion joint.

The PO looks like he tried to fill a couple of sections but its all cracked, so i removed it.

If you Google concrete expansion joint fill material, you'll find plenty of products to use.

Thanks Nostraquedeo.

Looks like there is wood in those gaps, if they are 2X4s I think I would remove the wood and then fill the slots with concrete. If there is wood in them I wouldn't just fill over the wood.

If you're just looking for a way to make it easier to roll over. I would cut some strips of plywood to fill the gap and tack some strips of 16 gauge sheet metal wider than the wood over lapping the concrete to level it all out. Cheap easy fix....

They do look like 2x4 or something else used as a form board. It alsmost looks like somebody poured the floor in section, leaving the forms in place pouring the adjacent sections.

If they are wood, get them out.

I'd take out the wood and put new pieces in, which are flush with the concrete. Putting in a cementitious patch would probably also work, but I'd bet it would be easier to get the wood perfectly flush.

I used a product from armorpoxy. They had several but the one I recommend is self leveling. It has a short pot life (20 minutes of less) so you need to work fast and make 2 or more small batches. It's flexible but still is hard enough to roll over it with jacks and other small wheeled devices. I think a gallon was about $80.00
