Garage Floor Repair

When obviously uneven, there are several ways to handle. The first option would be to build a wood sub-floor, which would cost around $2,500. Or, remove the existing concrete pad and then pour a new reinforced pad, which would cost around $3,500. The homeowners in this project chose the new reinforced concrete pad with the marginal cost difference.

1. Using a laser level, ascertain the levelness of the existing cement pad in the garage (figure A).

2. The professionals came in since the project was not a do-it-yourself type project. First, the old cracked concrete floor was removed (figure B). Also, in our homeowner's case, they had the driveway removed next to the garage as well to create a landscaped entrance.

3. A layer of base rock and sand was layered on the floor and tamped level with a motorized tamper (figure C).

4. 2x4 boards were installed to create a form for the new wall (figure D) and a sheet of plastic was added as a vapor barrier.

5. Holes were then drilled into the side cement frame of the garage and filled with epoxy so that rebar could be installed in a grid 24 inches apart (figure E). The rebar will enable the concrete to stick and reinforce/support the floor (figure F).

6. After a calculation was made about how much cement would be needed, the cement was ordered and poured (figure G).

7. Once the pour was complete, a bull float and metal finishing trowels were used to smooth out the surface (figure H). Wet set anchor bolts were placed into the concrete–these will be used later to attach the wall (figure I).

8. Moisture helps the concrete cure (figure J). It is safe to build on after 48 hours, but not strong enough to drive your car on. This would take about 20 days.
