Prefab concrete garage - water running in

Jon Frost · 27 May 2008 at 21:01

Hi all,
I've got one of these free standing concrete panel, prefab single garages, which is resting on a concrete base.
When it rains quite heavily, the water runs in under these panels, in to the garage area.
Any suggestions on what I could used to block these gaps please, to make it water tight. I thought of using expanding foam, but im not sure if that would work.

Thank you.

Jon

How big are the gaps?

I would say 1cm in the most extreme areas. Much less than this in most places.

Silicon gel stuff squirted out of a tube! (like you can put round windows, baths, etc)

I did think of this, but im not sure really.
It would be messy to apply and rather expensive.
I also dont think it will 'grip' to the cement, either the floor or the panels very well.

Thanks,

Expensive? Its about £2 a tube, and you squirty it out like a gun, FAR less messy than any expanding foams

Well its more than £2 a tube, last time I checked.
I recon 7-10 tubes @ £4 would be about the cost.

Probably just the one tube of expanding foam. IF, you think it would do the job in hand?

Thanks,

Yeah its £2 for that cheapo nasty sealant stuff...I suppose the cheaper method would be just to used concrete/motar.

Or if there are not that many panel gaps just fix some varnished wood which will look pretty to the gaps. I presume the rain is just forcing/seeping through. Just something to deflect the water.

MUSTARD!

failing that, some sort of waterproof sealant from in a tube. you can get them in poundland I think lol.

My dad had a similar problem years ago, we put in some drainage around the garage which sorted it, took the water away to the sewage.

Just use a good ol' bit of crete

mix up a bucket of cement and just patch the lot up?

2nd I've seen in a few days :\ although the other one was actually relevant to the post

Small bag of cement, big bag of sand (sharp or somthing) and some of the waterproofing additive (comes as a thick gluey type liquid in bottles).

Mix it all up and generously shove it in all the gaps it should do the whole garage..

I'm no builder tho...

hi guys, fixed this ages ago, used some 'lead sealer' which is really really great stuff. Grey as well

My mate had the same problem.
He used loads of expanding foam and it sort of worked, sort of.

This has been a recurring problem with my garage. It's extremely hard to stop water finding its way back through again so I gave up trying to stop the water and now I channel it instead. I use a corrugated plastic skin to channel it to a gutter then drain it that way. It's the only permanent solution. Water is stubborn and will eventually work through any sealant you throw at it.
