10 Easy Steps on How to Raise a Floor on Concrete Slab

Step 1: Mark the Area for Removal

The first step is to mark the area that needs to be removed. Measure and use a chalk line or straightedge as a guide for cutting down into the concrete slab. Be careful not to cut beyond your measurement.

Measure and Use a Chalk Line

Step 2: Cut Out Sections of the Concrete Slab

Once you have marked out the area, use your concrete saw to cut out sections of the existing concrete slab. Make sure to wear the necessary safety gear, like protective goggles, during this process. As you do so, remember to keep cutting lines as straight and even as possible.

Step 3: Remove Old Material from the Area

Use a chisel and hammer to break up any excess material and remove it from the area completely. If there are large chunks of concrete, you may need to use an electric jackhammer or masonry drill bit for more efficient removal. Don’t forget to wear the protective goggles during this step.

Step 4: Prepare the New Foundation

Mix the latex modified concrete mix according to package instructions, then spread it evenly over the area you are planning to raise. Use a trowel to level out the surface and create a stable foundation for your new floor. If necessary, you can also use a leveling compound to fill in any dips or crevasses for an even finish.

Step 5: Attach Plywood Sheets

Once your new foundation is set, use heavy duty adhesive to attach plywood sheets on top of the concrete slab. It’s important to ensure proper alignment so that no gaps are left between each sheet. Another option is to use screws and nails instead of adhesive.

Use Heavy Duty Adhesive to Attach Plywood

Step 6: Apply Leveling Compound

Cover up any remaining imperfections with a layer of leveling compound. This will also help out any bumps or dips in your new floor and ensure it is perfectly flat before installing any tiles or flooring. Try to use a trowel for a smooth, professional finish.

Step 7: Install Floor Coverings

Now you can install the tile or wood flooring of your choice! Measure and cut pieces as needed to ensure they fit properly, then use nails or screws to secure them. You can also use adhesive if needed.

Step 8: Apply Grout

Once all the floor coverings are installed, applying grout between each piece is time. Make sure to spread the grout evenly so that no gaps are left unsealed. Otherwise, moisture could seep in and cause damage to your new floor.

Step 9: Clean Up and Allow Time for Drying

Finally, clean up any excess material from the project area and allow plenty of time for everything to dry completely before walking on it. Additionally, check for any loose tiles or flooring and make sure everything is securely attached. If you find any loose pieces, reattach them immediately.

Step 10: Enjoy Your New Floor!

And there you have it – how to raise a floor on a concrete slab. Now you can stand back and admire your hard work, knowing that you’ve just completed this project easily! Enjoy your new floor! Remember, if you ever need any assistance, don’t hesitate to reach out to a professional for help.

5 Additional Tips and Tricks

Use a Drill to Make Holes
  1. Use a drill to make holes in the concrete for inserting fasteners that will help hold up the floor joists.
  2. Use insulation to help minimize heat transfer between the existing slab and the new floor.
  3. Install a subfloor over the existing slab, adding extra support for the new flooring material.
  4. Make sure to properly seal off any plumbing or other utilities that may run through the slab before starting work on raising the floor.
  5. Test your work by walking on it before replacing your furniture and other belongings to ensure everything is safe and secure.

Following these tips and tricks, you can raise a floor on a concrete slab with minimal effort!

5 Things You Should Avoid

  1. Do not attempt to remove the entire concrete slab; this can cause serious damage and be hazardous.
  2. Do not try to raise the floor without proper support underneath; this could lead to a collapse of flooring materials or injury.
  3. Avoid cutting into existing electrical wiring or plumbing that may run through the slab, as these services need special attention from professionals in order to be done safely.
  4. Keep tools away from combustible materials like carpeting and furniture when working on raising the floor, as sparks may cause fires or other accidents.
  5. Do not use shims or wedges to lift up a wooden subfloor above your existing concrete slab; this is dangerous and can create weak spots in your new floor surface.

By avoiding these mistakes, you can ensure a safe and successful job of raising your floor on a concrete slab!
