DIY Easy Big Crack Repair In Concrete Floor

Using a hand grinder I leveled the floor on each side of large crack and widened it to the wide of the grinder. Then I filled the deep cracks with cheap fine grain sand to make sure it was full all the way down deep. Then I went the easy route and got the pre-mixed concrete mix sealer. Poured in well and had a very strong finish. I cant feel the crack at all anymore.
