The approximately one yard square section of concrete walkway directly in
front of my front steps apparently settled improperly after it was poured
resulting in pooling of water when it rains. What would be the most
effectiveway to fix this? Will it require that the section be ripped out and
replaced or might it be possible to simply pour some more concrete on top of
the existing slab where the depression is? Does anyone know of a 'do it
yourself' website that would have info on this kind of thing? Thanks,
The technical term is "birdbath".
One clever remedy is to drill a small hole through the slab at the lowest
point. This won't stop the puddling, but it will allow the water to
eventually drain. A Tapcon bit would be quite suitable for this.
A bit more effective would be to neatly saw-cut all the way across the slab
there, but that requires more elaborate tools or expense.
I did try to drill a couple 'drainage' holes but don't think my drill bit
was long enough (I drilled down four inches or so). Am reluctant to go out
and buy an extra long drill bit just for this but suppose it will be less
expensive than replacing/repairing the slab so Ill give drilling another
Tried the drilling solution w/a 5/8" diameter 13" long masonry drill and
couldn't even punch through the concrete! I was able to get down about 3-4"
after about 15-20 minutes of effort but that was it. I'm wondering if there
is some kind of steel basin that the concrete was poured into that the drill
bit can't penetrate? I paid $15 bucks for a decent bit so don't think that's
the issue. Weird...
Use the Tapcon bit I suggested, at least for a pilot. They come in long
A 5/8" hole in concrete is huge. The bit will rapidly dull and you can't
exert enough pressure by hand anyway, if there's any granite or quartz
aggregate in there. You have to increase the pressure by starting small
and take it in steps.
As noted, if you have good drainage under it, you might get by with the
drain holes, or you might wash away more soil and make matters worse.
Depending on the specific situation you may also try digging it up or
adding a layer on top ( I really don't like this one) or maybe mud jacking
may work. You will have to have someone who does mud jacking take a look,
not all situations are good candidates for it. Look in the Yellow pages
under the concrete companies or ask around. They drill a hole or two and
then pump a concrete mix into the hole lifting the existing slab and filling
the area under with fresh concrete.
If it's only a square yard, in front of steps, it shouldn't be a big
project to just fix it right, especially if it freezes in winter in
your location. I'd cut it at a convenient spot, or at the first
expansion joint after the steps, break it using a sledge hammer, make
sure it has a good compacted base and repour it. The biggest headache
is getting rid of the debris.

You can try to spread on a topping mix. I have done this. But getting the
finish to match is a bit tricky. And will it hold? Maybe, maybe not. The
repairs I did were about 7 years ago, and it did hold. But still, it does
not look identical to the original pour. However, it got the water going
where I wanted it to.
A drain hole will just plug up or free in the winter.
