We just redid our driveway, patio etc with new concrete. It is 6"
gravel, 6" concrete with wire mesh on the driveway and 5+5, no wire
Unfortunately, a kid stepped on one place on the driveway and there is
a imprint of his step about 5mm deep or so. My wife is livid about
this, as she is wont to be in general.
So, I am thinking if I can fill the hole.
My idea was to take a solid epoxy 100% solids from raka.com, which I
have, mix with portland cement for color, and apply to the imprint. It
is very clean right now and is not contaminated with oil etc.
Would this work or not? It is in the worst part of the driveway (next
to the road). We have snow, ice, salt, etc.
1.) I think there is a latex coating which helps concrete stick to concrete.
B.) New concrete bonds to itself pretty well.
You will have a hard time getting a perfect color match with any material
other than the same stuff the driveway is made of. If your wife gets livid
easily, the outline of a footprint in a slightly different color will
probably bother her.
Here's an idea: Chop out a rectangular recess and inlay a tile with your
house number on it. Maybe your wife would like a second tile inlaid with
her first name on it.
Or just fill the footprint with a concrete slurry and hope for the best.
Your patch idea will probably NOT work. Go ahead, you're no
farther behind. The color will not blend, I suspect. Make sure
to mask around what you do - see below.
One idea that might work:
Call the concrete man. Ask if he has a core drill with a large
enough bit to encircle the kid's foot print. If the print is not
centered, could you drill several holes to create a pattern or
enough to do the address? Drill and Chip out the circles about
1/2-3/4 deep. Fill with epoxy or high strength pavement patch,
embed a design or number if desired. Trying to make square or
diamond, straight line cuts will be quite problematic, that is why
I am suggesting round. Mask or cover quite an area around the
area, any slop will not clean off and will stain and discolor what
you have. You will probably be in the next size dog house if you
stain or discolor it. My dog house has lights and AC!
Keep the whole world singing . . . .
No matter what kind of patch you do, it will not match the original.
Personally I don't think it is much of a problem. I have seen concrete jobs
where they deliberately put the kids hand prints in the cement. So you
could adopt the kid or get a new wife.
Another course of action would be to have that section cut out and then have
an identical section at the other side cut out so they look symmetrical.
Refill with tile,or a paver, or a different color concrete. As someone else
suggested, cut out the foot print and put new concrete in with your house
numbers etched into the concrete or use some bronze numbers.
I'd go for that. I've patched the old concrete on my walks numerous times,
trying to find something that will last and match. Getting it to last is not
hard. Getting it to match is almost impossible, in my experience.
As for getting it to last, I haven't had much luck with the cheap patching
concrete from Home Depot. The best luck I've had is in using a polymer
bonding "paint" followed by a high-quality, polymer-modified patching
concrete that I got from a professional mason. It's still there after eight
or nine years.
I etch my old concrete with muriatic acid but that isn't necessary with
fresh concrete. That does seem to make a difference when you have to feather
the edges of the patch. But I prefer to undercut the old concrete rather
than feather. In fact, I have a job like that facing me right now, before it
Sinking a bronze or tile marker of some kind into the concrete sounds good
to me. Then I *would* use epoxy, to bond it in place. But I'd make sure it
was a close fit to begin with.
No, no, clearly the only wife acceptable solution will require applying
an additional 1" of concrete to the entire driveway so there are no
areas that don't match. While he's at it he needs to have it colored and
stamped to look like stone.
Wait 'till she watches that 1" layer delaminate. <g> It's very difficult to
make thin layers of concrete stand up. There are some fancy, modified
concretes made for the job, but I've seen some "veneers" applied like that
in my town, by knowledgeable people, and I'm not impressed with the results.
I live in an old town with big trees whose roots knock the hell out of
sidewalks. It's like an experiment in concrete repair, and the results often
aren't pretty. Mud jacking works pretty well, but a lot of the old concrete
is weak to begin with and it cracks.
I'm thinking of using bricks for my front sidewalk, set in sand. It's short,
and there's a really big maple, 74 years old, right on the edge of the
sidewalk. There's no way you can keep concrete intact there for very long.
Used bricks work well and can easily be repaired if necessary. For
driveways the 'paver' blocks work out very well and will withstand the
heavier load of the vehicles. Glen Gerry is one brand of pavers. They
have a big factory on RT 61 in PA near Shoemakersville. A friend of mine
just did his driveway and he located on a main road and has had a number
of inquiries on them. He is thinking about going into the business of
installing them. :)
Oh, yeah. I drive out I-78 regularly. If I had a pickup I probably could
save some money by getting them there.
I've installed pavers in sand around a swimming pool (my parents', not
mine), and it was a pretty good solution to ground that kept settling and to
roots that kept heaving. Every year I'd adjust a few bricks.
Maybe next spring.
