concreate water issue

randomi15

hi all,

water stays on my driveway due to the way it has been concreted

I am thinking of drilling a hole in the middle which is around 200mm or 20cm and then put a drain cover on it .

is there a hole saw for concrete and what is the smallest size for drain hole?

many thanks

Yes, you can buy masonry hole saws. But I very much doubt this would solve your problem - the soil underneath the concrete is likely to be / should be very well compacted, so water will have a hard time draining away. Is the driveway perfectly level ? It shouldn't be. You need to install a channel at the bottom edge to allow the water to flow into a proper drain.

sorry I should say it is not my driveway
it is my garden at the back which was concreated before I purchased the house and done poorly

You've confused me!

Seriously though, cutting holes and fashioning a drain won't work. As Ebe Scrooge says, you need to establish if there's a fall across the concrete, you will need a drain of some sort at the lower edge. If there isn't a fall (and your description suggests there isn't) then your only options would appear to be to get it resurfaced properly or live with it as it is.

As above, I'm afraid.

You could hire a drilling rig and diamond core bit, drill a 200mm diameter hole but the water would just pool in there.

You "could" cut a channel from the lowest point where the water is pooling, essentially creating a run off. Can't see it being easy on the eye, but then again, is a slab of concrete?

it is a big slope on existing concrete so only way i can see is creating a drain channel

How does water stay on it then? Have you got some weird special gravity or something?

It gathers in one spot so i need to create a drain hole

Does that make sense?

How many aliases do you have?!

So you have a sloped driveway but somewhere on that slope is a depression where water pools?

So you've got a sloped area of concrete, with a depression in it where water collects ? Would it not be far simpler to just mix up a small amount of concrete and use that to fill the depression ? Then the water will just run off naturally.
