can I drill a hole in my concrete ground to use as a water drain?

My home had the backyard concreted over what use to be a dirt ground backyard. There is no nearby drain for rain water to drain to and i am getting standing rain water after a heavy rain particularly in one area. Right now I use a broom and sweep the water towards the nearest drain but I was wondering could I drill hole where the water is standing and use it as a drain? I know before when it was a dirt backyard the rain water drained in the soil so can I drill a hole to the soil insert a pvc pipe and allow the water to drain? Thanks in advance

You will be trying to drain hundreds of square inches of surface area into a (maybe) 9 - 12 square inch hole. That small of an area opening will quickly saturate the soil and be of little or no use.

Are there any relief cuts or control joists in the slab? Just drilling a hole will get clogged with dirt and not sure it would have the same effect as punching a hole in a plastic bag. Can you upload a picture of the area? http://www.doityourself.com/forum/el...rt-images.html

To answer your question directly:

Yes, it is easy to drill through concrete with the right equipment. You would need a core drill and a core bit. Both can be rented, my rental place has a max core bit of 10". The drill would need to be fastened to the concrete in order to drill the concrete.

I will try get some pics of the area on by tomorrow. okay so far it's not sounding that simple. if drilling the hole does not work what if I remove a section of the concrete and place pvc pipe with a drain and then re cement the area.

Where would the drain end? In a storm sewer, gutter, or somewhere else on your property? I would consider cutting a channel through the concrete to a proper drain area, making up a concrete or plastic channel to carry the water, and then put a metal grate over the channel.

yes the proper drain would be best but it just seems to me all the years since the house was build the rain and water soaked in the dirt when there was no concrete ground and to put a drain from the concrete ground back to the dirt ground should be okay. being that the dirt was originally the place where the rain water was going. correct me if I am wrong. right now after a heavy rain it is just a puddle of water not flowing like a river.

If you are to remove and replace the concrete, then just install the new section with the proper drainage to prevent puddling. Am I missing something else?

rock13979, drill a hole where you get the puddle. Then cut a 3x3 section around the hole with a Partner saw. You can rent them.

Try to pry it up with a pinch bar (digging bar). Hopefully, it will come out in piece. If not, don't worry about it Dig a hole large enough to install Flo-Well. Home Depot has them, in the plumbing isle.

Flo-Well Drain Inlet with Grate - The Drainage Products Store

Drill holes in the side of the barrel. Modify the top to accept a hose from the drain. Drop it in the hole & surround the barrel with gravel. Put the concrete back, if it's reusable.

Rather than use that great I would much prefer using something like this: Flo-Well Storm Water Leaching System - The Drainage Products Store which are designed to dissipate water.

Well, I'm no expert, but I've addressed drainage issues before.

It was kind of a clay layer over soil (since the builder had stripped off most of the topsoil). I used a 4" auger and went down 3'-4' put in perforated drainage pipe, then filled it with large gravel wrapped in a soil sock. It worked great. No more soggy ground around the deck.

I did have to do this about every 2'-3', so I doubt one hole would work in your situation. Another concern would be what the heck is down under the holes? Cut a power, water, or sewer line, and it will get expensive fast.

That's not a bad idea either. It's far less work. If it doesn't work, the dry well idea can still be done at a later date.

kinda depends on how much water, no ? the underground utility locator svce is free & required by law IF anyone excavates,,, 1 good idea - call the 800-dig #,,, you can just rent a hammer drill - no need to diamond core - that's not a piece of equipment the ignorant need to know anything about operating - its a pro job - so drill some holes & see if that works - you can always enlarge the size of the 'drywell' later on if the holes don't provide enough space

ps - i am an expert :-)
