Re: garage flooding when it rains 4Jan 09, 2011 7:20 am Hello i have the same problem almost, my garage leaks with a small to medium rain fall and only leaks at rear, 1 full side and only half the other. I have tried to put dirt against it to stop or a least slow it down but has not worked. I was wanting to know is there anything on the market that can be placed inside or out to stop water from entering like firbo or tar something! I have all my shed stuff under my padio because its drier there then in my shed. If anybody has some ideas i would like to here them. Thanks Allan Re: garage flooding when it rains 5Jan 09, 2011 7:41 am My garage has a fall of 1 in 50 both for the roller door and the normal door at the other end. Strangely enough the Council wouldn't allow it at first since "if the car is left without the brake on, the car may roll into the roller door". I said I was willing to take that risk and they let me have my way.

It sounds to me as though your garage floor is close to or below the ground level outside. Piling dirt against the walls will make things worse as it will encourage the walls to remain damp. You need to make sure the ground level along the walls of the garage is at least 100mm below the garage floor level and sloping away from the garage. The Harder You Try - the Luckier You Get !

Re: garage flooding when it rains 7Jan 09, 2011 7:52 am Our garage slab has rebates at all doors, so the doors sit in this lower part of the slab. Not sure if rain can still be pushed up this little step Some improvisation ideas from me: Maybe you could use something that works on the principle of those flexible road divider lines. For example, build up a flexi strip of glue (or some kind of "no more gaps" product ) along where the doors sit, but a little bit on the inside of the garage - just make sure it's built up high enough. When it's dried, it should be flexible enough and it shouldn't get unstuck or damaged with light foot traffic (if there will be any). The problem I see with this is if the strip would stay stuck to the concrete - so it would need a really good cleaning / prep. So, not sure if you could drive the car over it, without breaking the bond. A quick band-aid type for sudden downpours (a temp solution only): Place some plastic or rubber material on the inside of the doors and turn them up against the doors. That should certainly prevent any rain, but need to be careful on the sides or where you have to join 2 pieces. You can use builders' flexible building membrane (not sure of the exact name) - the stuff they install at the bottom of the brick courses (or thereabouts ). It's wide enough for your needs and it can be cut to the required length. Needs to be secured so it doesn't just slide flat. Unfortunately, has to be re-applied every time it rains - so only good for emergency. Ooops, just looked up that UK product - that's similar to what I had in mind with the sealant/glue, but seemingly without the issue of breaking the bond (plus it's all built up for you already).

You need to make sure the ground level along the walls of the garage is at least 100mm below the garage floor level and sloping away from the garage. At back of garage the slab was higher then the ground and the sides are about 100mm into the ground, but it seem to flood more at rear so that's why i put more dirt against it to try and stop it. As for pictures i will see what i can do. Until you find the cause of the flooding you need to take action to mitigate potential damage to your home.
