Watched a guy at the Home Depot in Rio Rancho fix a cracked foundation with epoxy in 20 minutes

I was picking up some concrete patch for a slab at my place and this older guy just started chatting me up. He said he used to work for a company that did foundation repairs and showed me how to inject epoxy into hairline cracks instead of ripping out the whole section. Has anyone else tried this method for small foundation issues or is that just asking for trouble down the road?

Honestly yeah I've tried that epoxy injection method on a couple hairline cracks in my basement wall. It worked fine no issues three years later but you gotta be real careful about diagnosing the crack first. If it's a structural crack or you've got water pushing in from the outside you're just covering up a bigger problem. The old guy at Home Depot was probably right for tiny nonmoving cracks but I wouldn't trust it for anything wider than a credit card. Also you need to make sure the concrete is totally dry and clean or the epoxy won't bond right and you'll waste your money.

@quinnj24 nailed it with the diagnosis part. I did the EXACT same thing to a crack in my garage floor about two years ago, and it’s held up perfectly through our New Mexico freeze thaw cycles. The epoxy injection trick is legit for those tiny hairline cracks, but you gotta really clean out the crack first with a wire brush and compressed air, otherwise the epoxy just sits on top. My neighbor tried it without cleaning first and his fix popped right back out after one winter.
