garage drainage problem
jabbahutt - 29/7/08 at 03:23 PM

Afternoon all

With all this Summer rain we're getting which is a lot of water in a small space of time my garage keeps flooding!!

The space in front of the garage is on a very slight incline towards the door and in front I have one of those half round channels with the metal grate on top.

Problem is that the water isn't draining out of the gutter thing into the soak away quick enough and the water is literally pouring into the garage.

Few times now lapse of concentration hgas meant things hace been left on the floor only to be ruined by the water and anything not paintedc is rusting to pieces due to the large amount of water.

Any easy to implement ideas to increase the drainage speed or short this problem out.

GRRR new build houses, no wonder Barrett homes are in so much trouble.

Any help much appreciated as this is really starting to make me mad.

you should be building a boat instead

Add a small bund (concrete, reubber, whatever) on the garage side of the drain. Works on mine. Only needs to be an inch high - just make sure the door still shuts.

Drill some holes in the bottom of the channel to let the water drain under it if it's not running out quick enough. Lift the channel out, dig down a foot and fill it with pea gravel underneath it.

The problem of getting rid of the water involves controlling where it goes! You could dig a deeper soakaway but the water has to go somewhere and if it goes there too quick, it could take your soakaway/gravel/earth/house with it.
I would firstly, make a sill under the door. Then consider digging a sump big enough to fit a submersable pump in and pump the water into next doors garage!
Lastly, if the water wants to get into your garage, let it. But make sure it scurries out of the other end!! Grind out a channel and then plop a hole out of the back of the garage.
It's hard to advise without seing the problem but HTH!

I think this ho wland drains are fitted. They sometimes use pipe that have loads of holes in it, wrapped in membrane and then the trench backfilled with fine gravel.

Your other option is to dig a trench to fit a gulley but route the end into a surface water drain if there are any close by, failing that into a foul drain. Most modern manholes have extra inlets that may just need cutting out to fit new pipe. All readily available from builders merchants.

Your options may depend on location of nearest drains, fall and if the driveways or paths are blockpaved or tarmac'd.

Post some pics if you want other ideas.

I have a similar problem - I think my `builder` friend who put the base down miss-read my instructions and thought I wanted a pond
In heavy rain I can get as much as 3 inch's of water in there - the base is actually lower than the surrounding slabs !

Clear out garage and raise the height of the floor a couple of inches with a skim of concrete .job done

How about (seriously!!) making a concrete speed bump type thing just inside the garage. That would keep the water out......
