How to Repair a Concrete Slab

To repair defects in a concrete slab:

  • Apply concrete resurfacer to fill up deep holes, smoothing it out with a trowel.
  • After the resurfacer has dried, apply a floor leveling compound to the entire area and allow it to dry.

  1. I was wandering if you could use that concrete resurfacer on the driveway and the floor leveling compound also outside? I have deep holes on my driveway, and it’s unlevel to, it has cemet on it?

  2. I live in NH. The concrete directly in front of my garage along the entire width of the garage is breaking up. It’s about 2′ x 20′.

    I need to repair this but I am not sure which is the best product and method to use.

  3. I built a bathroom & walk in closet in basement under front porch & front porch cracked in triangle shape and slab dropped slightly (about 3/4 inch at deepest). What is the best way to repair it?
