Please Help New concrete garage leaking :(

Got a outside photo showing base of wall otherside,can advise better then, but one solution is a angled fillet of waterproof mortar running along base of wall, this fillet can also be painted with a bitumen sealer.

See rough sketch below, but you also need a way to get rid of the water to a drain,gully, rather than it pooling on concrete base.

 

I don't know if it will be an issue for the floor tiling as it is... but presumeably there is no damp proof membrane there either. I suspect there will need to be one before tiling. I'm only DIY so this should be checked further.

Also, if the supplier knew the intended use of this was as an office, not just a "car shed", it's possible they may have not advised you correctly when making the purchase, with regard to a suitable base, so you may have some comeback there. Again, you'll need to get proper advise on that!

I hope it all works out OK for you.

Regards,

Cando

 

Thanks, I would first put a bead of sealant there first along the edges,Everbuild Silcone 825 from the competitor would be my choice, then go over that with a waterproof angled fillet of mortar.

Also I wouldn't have taken the plaster down to the concrete base, but kept it short by up to 25mm, could then put another bead of Everbuild Silcone 825 the base.

 

As Kiab says, you need a water proof fillet between the slab and wall.

Id be looking at this ://www.uksealants.co.uk/sikahyflex-250-facade-sealant-300ml.html

 

If the garage was being used for other than car storage, I would have gave floor & 100mm strip at base of wall a coat of Everbuild Blackjack DPM, then laid a waterproof screed, to prevent the ingress of water & moisture from the ground.

Everbuild 825 sealant:

It all looks a bit rough and ready as none of the panels have been aligned correctly.
Do they not use some sort of compressable gasket to seal between the slab and the panels.

 

Usually a sealant is used when joining panels together.

 

None of the panels have been aligned correctly,but I was talking about a compressable gasket not between panels.
But between the panels and the floor.

 

Rough and ready indeed, what's going on with the corner not having a brick Patten on it, as for lining up the panels I've seen brick walls rougher, but yes it looks bad.

 

Didn't think they still used the grey sticky stuff, that was being used nearly 25 years ago, last two garages earlier this year seen erected they used a sealant in a tube.

 

Thought you were refering to the rolls of grey sticky sealant for sealing panels.

 

Have a garage similar to yours. Same style of concrete panel. 70's build so Harled not a nice brick pattern...but there is a fillet on the inside and out. Mine is leaking a little bit, but only where the fillet has cracked. Whatever gasket or join between the wall slabs is cracking in places and will be replaced at some point.

IMVHO that should sort it out as others have said. No bell cast on mine, they rendered down to the fillet but like I say it's mostly dry.

Asbestos roof needs changing tho ;-)

Best of luck.

 

Ignore the bell cast in the sketch, should have made that clearer in my ealier post, was just trying to make clear about the cement fillet & it's location & purpose.
