New Concrete Garage Floor Slabs in Salt Lake City, UT

The soil there is often fill placed against the foundation that settled after the slab was poured, and meltwater entering at the door softens it further. Where the ground is old lake clay, its swelling and shrinking add to the trouble. A new slab needs that fill dug out and replaced with compacted gravel.

Size, how hard the old slab is to remove, how much base needs rebuilding, thickness and access set the price. A tight garage with a low door can limit equipment and add labor. Quotes are free and follow a look at the garage.

It depends on your city and the scope. A straight replacement inside an existing garage sometimes doesn't, while a new garage or a slab tied to structural work typically does. Any digging starts with an 811 call, and a new driveway approach in the street right-of-way needs a city permit.

If you might coat it someday, yes. Without one, moisture from the ground can rise through the concrete and push on a coating from below, which is a common reason coatings blister on older slabs.

About 28 days at minimum, and longer in cool weather. The concrete has to gain strength and dry down enough to pass a moisture test, or the coating may not grip.
