Building a dam...

A friend has a problem with rain water running down her drive and under her garage door. There is a drain that runs the full width of the door but that leads to a soakaway which is overwhelmed by heavy showers.

She has no intentions of ever putting a car in her garage and it seems to me that a simple solution would be to make a 2" high dam inside the garage to prevent water ingress.

The existing garage floor is concrete. What would be the easiest way to make such a dam (cheap would be good too) that I could be reasonably sure would bond to the garage floor well enough not to let water seep through? Plus points for ease of future removal if necessary.

Probably depends on how robust it needs to be but a length of 3x2 glued down with Gripfill or similar would probably do it. Then a bit more Gripfill to fill around the edges.

I had a little water occasionally blowing under my garage door. I happened to have a length of arris rail handy, which I screwed to the concrete, first squirting some no nails onto the bottom surface.

So far I have had about 30 years' successful operation.

If she intends ever to sell the house, it may be better to go for something less Heath Robinson. There are loads of purpose-made garage door seals around, eg this one for £33.

A whole range of solutions here:

That does look like it would do the job. Thanks!

Tim

Thanks for the suggestion. I suspect she?ll go for the Screwfix threshold strip option though.

It is not going to work, Water will get through. I'd think the best bet is to bite the bullet and extend the drain so it has some way to drain, rather than to back up and flood.

Fine until it freezes.

Hmm, I think the issue of the original may well be the underground gulley that is blocked up and gives a lot more water to be kept out. Brian

Please don't post any more screwfix pages it greys out with an exhortation to accept cookies, it is like their hide.

Tell her to get her beaver out ;-)
