Sidewalk concrete patch
 

Sidewalk concrete patch

Greetings,

I live on a hill. Everything shifts a little as time goes
by.

My concrete sidewalk slabs misalign. The corner of one
will elevate up to about 3/4" above the adjoining one.

So folks won't stub their toes, I've patched such places
with vinyl concrete patch and regular concrete mix. Neither
lasts thru a winter before cracking to hell and gone.

Anyone know of a better patching substance to use in
this situation?

TIA,
Puddin'

It's very difficult to get something to "stick" in that situation. My
city uses asphalt as a temporary fix until they can repour the
sidewalks (petty tacky)

I would check w/ SIKA for a a repair matrerial but maybe a mechanical
fix would be better.............

Hilti 4.5" diamond grinding head?

Lever up the offending coner & pack sand under it?

repour the sidewalk but use WWF or rebar dowels from "slab to slab"

cheers

Nothing is gonna hold in that situation. If the 2 slabs the patch touches
are moving independently of each other, anything will pop loose. 2 possible
cures, neither pleasant or cheap. If the situation is reasonably stable (ie,
the slans don't go up and down with the freeze-thaw cycle). a mudjacking
company may be able to level things out. But the proper cure is really to
tear out and replace the offending slabs, with proper substrate and
drainage, and removal of (or rerouting around) any tree roots that may be
lifting the slab.

As in http://www.sikaconstruction.com/ ??
I took a peek, couldn't sort it out.

Fear it'd be too expensive/hard-to-use.

Lever up the offending coner & pack sand under it?

Should've mentioned bad back, other health problems.

Maybe 20 years ago, when I could do such work a little, I poured
footings for each slab in backyard, mounted rerod. Worked too,
they haven't shifted.

No evidence thay are actually moving. Think it's just expansion/
contraction (i.e. freeze, thaw) causing patch to break up.

2 possible
cures, neither pleasant or cheap. If the situation is reasonably stable (ie,
the slans don't go up and down with the freeze-thaw cycle). a mudjacking
company may be able to level things out.

I may look into this. Just look for 'house piering' or somesuch
in the yeller pages?

But the proper cure is really to
tear out and replace the offending slabs, with proper substrate and
drainage, and removal of (or rerouting around) any tree roots that may be
lifting the slab.

If my rich uncle dies (grin he doesn't exist), that's what I'll do.

Seriously, no trees, but I'm working on a mutant shrunken budget.

Thanks,

Look for "mud jacking" in the yellow pages. That is the term for
drilling a hole in the piece that is mis-aligned, then injecting mud
under the slab to lift it back into alignment. The hole is then sealed
back up with concrete.
