Lifting & Leveling Sidewalk

How much sidewalk we talking about?

I did it once with just one section that was sinking and will never do it again. A lot more work and more strenuous than expected. Just replace.

this ^^^^^^^^^^

and even after you lift it and do all that work, 80% of the times it shifts again and isnt level in just a year or two

if you insist on saving it, then dig it out, and a little dirt in the low spots and then place bricks under it to level it. after you get it leveled, lift the slab up and spread sugar sand to level the ground out to the level of the bricks and then set the slab back down. finally add sugar sand up around all the edges so it can help fill any remaining spots under the edge of the slab.

if you really want it to be level and stay level, then get rid of the slab, and pour a new one for it

Thanks for the feedback. I’d be doing 3 sections. Each are 48” X 42”. I’ll have to mull this over.

For reference, a 4 foot square by 4" thick section of concrete is around 800 pounds.

It is doable. I've done it twice. My best success in lifting was digging out enough to get a 4x4 or 2 under the edge, using some blocks as a fulcrum and levering the slab up enough to jam some brick under it to secure. I dug out a footing and poured in a bag of concrete. Still holding after 20 plus years.

make sure there's no water or sewer line underneath that could get crushed in the process.

The one I used looked like it was some type of franchise operation.

Do you mind sharing how much it costs per sq ft?

It's called foam jacking or mud jacking if they do it the old school way with mud/sand
