I have about 40 years old house and I believe my walkway is not that
old, but significantly old.
It has deteriorated so such an extent that the gravels can be felt
while walking bare foot on it. No cracks though.
I want to get this repaired and I want to do it myself.
- Replace it? It is about 40 feet by 3 feet curved walkway.
- Re surface it? How?
Any suggestions, please? I am sure there are folks, who had gone
through this before.
You can certainly replace it, but that's the hardest solution, and
probably the most expensive.
If'n it were me, I'd look into the epoxy/gravel surfaces. They're
pretty, last a long time, and you don't have to do the work. You wind up
with a finish that looks like exposed aggregate concrete with a gloss
sealer. I suppose you can do it yourself if you want, but it's messy.
The pros mix epoxy glue with pea gravel in a mixer, then trowel it on.
My wife used to manage an apartment complex, and she had repaired some
concrete stairs that were starting to rust out. That was 25 years ago,
and they're still there, as far as I know.
There are many types of surfaces you can put on, so go wild looking on
the Web. Come back here for free advice on what is good. (Disclaimer:
Free advice is worth what you pay for it.)
Where are you? Is the walk subject to freeze/thaw? Is the top
surface eaten off?, perhaps from salt? There are epoxy and other
topping cements. They are expensive and depend on the existing
concrete being sound. They work better where they do not have to
The best answer is to remove and replace. 120 SF of new concrete
4" thick is about 1 1/2 CY. Can you get a concrete truck to it or
is it a wheelbarrow job? Realize that a yard of concrete is over
2 tons. When it is wet, it is even more. The finishing labor is
extensive if you have no experience.
Keep the whole world singing . . . .
How do you feel the gravel under the concrete especially if there are no
Anyway I'm replacing one (sidewalk) in the next few weeks. I'm in the Bay
Area so we don't have the ice heaving problem.
This is what I do on my sidewalk. Jack hammer and saw cut and resue old
concrete for another project - dump fees are ridicules here. Level base to
4" below grade, reuse existing gravel and add as needed. Compact with plate
compactor - they say 98% compaction but I just run the compactor over a few
more times to make sure. Lay two #3 rebar sections 2' apart in the long run
and 2' on center on the short run and stand the grid off 2" about the base
and 2" away from the either side of the pour. Wire tie all rebar crossovers.
I buy a bundle of wire ties and use that little tool with a hook to twist
the wires together. For this time I buy pre mixed bags using two electric
concrete mixers. I also use a concrete vibrator and a 2x4 to screed off the
concrete. Start early in the morning and hopefully finish early enough to
see Property Ladder. I had one pour in a cold day where I was still doing
the finishing by 2 am.
I do premix (the most expensive way to do it) since I'm doing it myself
without help. Another way to go is to have the mix delivered and you buy the
cement and mix it yourself. Best and fastest way and perhaps cheapest, if
you have help, is bring in a concrete truck. Regardless what you do
everything is pretty straight forward with the exception of finishing. Each
pour is different, temperature will dictate how fast you must work as once
its set, there is no easy way or redoing it. Good luck.
