Keep Concrete Crack Resistant

$50
2-4 Hours
Medium

There's nothing worse than a cracked, heaved, or sunken concrete pad.

Chances are you've experienced one of these 3 things if you're a homeowner (i'm in this club myself, and unfortunately it doesn't involve a cool jacket).
Fortunately you can avoid issues of this nature by making your concrete's expansion joints watertight.

    how about sunken slabs? is there a sure way to fix them without pulling up the entire piece?

      ONE is Slab Lifting where they bore holes and lift the slab level and back fill by pumping mortar into the holes under the slab.
