Slabjacking Tips

Slabjacking

The first challenge you face is getting an experienced slabjacker. An experienced slabjacker can usually determine why a slab settled. He/she can also tell you if the settling is complete. Remember, some settling continues for years!

Make sure that you ask what is going to be pumped under your slab. Avoid slabjackers who simply use topsoil or drilling mud. These materials just aren't the best products. Professional slabjackers use different mixtures and combinations of materials depending upon the job. BUT, these mixtures always contain Portland cement. The cement gives the grout strength after it gets hard and prevents erosion of the grout.

Ask the slabjackers if they will collect and save the dust from the drill holes. Request that this dust be mixed with the material used to plug the drill holes at the end of the lift. By doing this, there is a good chance that the color of the holes will closely match that of the slab. Failure to do this will result in a polka dot slab.

As usual, ask for copies of Worker's Compensation and liability insurance certificates when you receive your bid or quotation. I know, I know, it says right on their contract that they have this coverage. Well, do they? A professional will not hesitate to give you copies of these certificates.

Why not call the Better Business Bureau? Ask if there are any unresolved complaints. If so, consider finding another slabjacker. You may pay slightly more, but it will be well worth it in the long run.
