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' |

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 Bob |

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. aem sends... |

My city uses asphalt as a temporary fix until they can repour the sidewalks (petty tacky) I would check w/ SIKA As in http://www.sikaconstruction.com/ ?? I took a peek, couldn't sort it out. for a a repair matrerial but maybe a mechanical fix would be better............. Hilti 4.5" diamond grinding head? 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. repour the sidewalk but use WWF or rebar dowels from "slab to slab" 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. Thanks, Puddin' cheers Bob |

If the 2 slabs the patch touches are moving independently of each other, anything will pop loose. 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, Puddin' |

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. -- NewsGuy.Com 30Gb $9.95 Carry Forward and On Demand Bandwidth |
