Grinding down concrete bump between driveway and garage

Don't most garages have this threshold to keep water out of the garage? Typically the garage door will close on the low side(driveway side). They do make a threshold ramp that you could place there but you will probably have to adjust your garage door stopping point.

Angle grinder with a diamond concrete grinding blade. Skim coat it with concrete topper to blend the finish. Use bonding agent.

If it’s too big for a hand tool, you can rent a floor grinder.

Or find a concrete finisher or a concrete specialty sub.

I would prolly call someone that does spray foam insulation to see if they can spray some foam and raise the driveway back up to where it should be.

This is his best option. If he tries to ground down even close to 2" at the garage slab he will start to come close to the rebar and end up with much bigger problems.

The correct way to build a driveway is to provide a ledge in the garage slab for the driveway to rest on. When the driveway subsides the ledge will cause the driveway to hinge at the garage instead of sinking.

just a little bit lower so it doesn’t take so much acceleration to get over it.

Before you finally fix it you need to practice power braking. Hold down the brakes and build some revs with the accelerator. Then slowly let go of the brake pedal and your truck will just barely climb over that bump without you having to have so much momentum.

I'm surprised more people don't already do this but maybe I'm the crazy one. Any time I have to accelerate up an incline from a dead stop I build revs before I let go of the brake so I don't slide backwards into the car behind me.

As for the concrete, it sounds like you've gotten good suggestions here.

Just cut out 3-4 feet of your drive way re pour the concrete drive

is spray foam that powerful or would you have to manually raise driveway first?

From videos I've seen it doesn't have to be lifted first, but I don't think it's likely something anyone that isn't geared up for it could do.

It involves drilling holes in the concrete in various places and spraying the foam in. I'm sure there's a science behind where to place these.

Then you have to patch the holes, etc....

Lifting

Yes, it will easily lift a driveway or a sidewalk. My area has clay soil and that results in home foundation issues. There are companies that level up whole houses using expanding foam. You don’t have to lift the driveway…or the house before you inject the foam. The expanding foam will lift the slab.

I’d fix the driveway to a proper grade. It’s going to keep subsiding unless you stabilize it
