Im pretty handy with a hammer but Im not so sure footed around concrete.

My question is this, my driveway was graveled about 13 years ago and we have been driving on it ever since. Do I need to dig it up, rent a roller and tamp it down, or can I just pour on it?

Thanks

For driveways, I'm not sure what would be recommended. I do know that you have to make a form for it.

Take a look at http://www.rusticgirls.com/landscaping/building-driveways.html -- seems to have pretty good instructions.

You can also do a search at your favorite search engine (mine's google) for concrete driveway "How to" pour.

Hi Kennedy,

It probably isn't going to make much of a difference, but if it were me, I'd go with the 1/2 inch. I presume you plan on crossing the rebar as well? You can also use some fiber mesh added to the concrete for some added strength.

After moving into our new construction house, we find the garage is 18 inches below grade (per site plan). The builder wants to pour 18 inches of new concrete on top of the existing floor. Can this be done? Please help!!

Hi Sara,

This is more of a construction question than a flooring question. But, my hunch is there could be a problem with that. I don't think the two layers would adhere and that could cause problems. I would suggest calling your local building department to ask about how that would work, and if it's an appropriate fix.

So....if the concrete was poured that way 'per site plan', then why does the builder want to pour another 18 inches of new concrete on top of that now?

You may have to take the original out and pour a new, appropriate one. For your sake I really hope not. I just can't help but wonder if your builder has messed something up and trying to cover it up or just wants to get more money. If it was 'per site plan', then it shouldn't be an error, right? Unless the whole 'site plan' was in error. Just thinking that the builder should be responsible if it was an error. Anyhoo, I really think your local building office would be a great help and help guide you on what you can do if something is amiss with what the builder has done and wants to do.

I am pouring a garage floor and not sure how to space my rebar for the floor. I live in Montana and not sure that would make a difference. Thanks for your help.

Hi Bill, That's really more of a construction question, I don't pour concrete or prepare the area before it's poured. You could probably find an answer by doing a search at your favorite search engine. Something along the lines of rebar spacing concrete garage and/or floor should work.

I am getting ready to pour a garage floor...28x38, 6" thick. How is the best way to go about keeping the concrete level when pouring? I thought about nailing some thin plywood, 6" high around the walls, then putting a piece down the entire center of the garage, and using them to slide a 14' 2x4 down keeping the concrete level with the top of the plywood boards. Would this work? If so, what happens if I leave the plywood strips nailed to the wall, and that one down the center? Will that cause a void for ground water (i have water puddling on top of footer when it rains) to come up? Where on the net can I find more detailed info on pouring a floor like this?

Hi Mike,

The questions you're asking are construction issues. I'm sure though, that if you went to your favorite search engine (mine's Google) and typed in forum concrete floor you'd find some good places to ask your questions.
