I found when the rain, together with very strong wind, the garage floor-slab ( neary the periphery of the brick wall side) will get a bit wet. This happened once or twice so far. Our garage has 2 internal walls plastered, the wall near the lot boundary is brick only. The rear access garage door ( the 820mm wide one) already got a strip of sealer. Is that normal? Thanks. Re: Do u garage ( interal) get wet when heavy rain? 2Feb 13, 2010 7:36 am In the massive storm we had last year I had rain come in under the rear pedestrian door as there is a gap and the rain came from the north in the wind, but that's the only time really. If your door is facing west or south and there is a gap underneath it wouldn't surprise me. If you go to bunnings you might be able to get one of those meal things for the base of the door that help stop the air coming in/out, it might help stop the rain too.

If not, the water is possibly just sitting there and is looking for the least resistant route to escape ... Does anyone know why an external garage brick wall "doesn't need" weep holes??

I was already tempted long ago to "construct" them, but wasn't sure if that would be wise ... many garages don't have them (but still doesn't make sense why not).

Re: Do u garage ( interal) get wet when heavy rain? 8Feb 13, 2010 11:52 am If it is a single skin then moisture ingress protection (Siloxane penetrant sealer) to stop ingress from external. Weep holes in a single skin have no relevance as the weep hole is for cavity moisture relief... though I could be wrong casa - I was referring to a relief point more than an engineered weep hole. A caulking chisel... Google says all other kinds but the one I am talking about has an angled face with a pointy end. Like a cold chisel but not a flat head it has an angle of about 60 deg. This could be a better description... Like a narrow chisel about 4mm wide but with a longer face If my camera was about I could take a photo Where you are coming from is where you are going to... Re: Do u garage ( interal) get wet when heavy rain? 10Feb 14, 2010 9:05 am Part 3.3.4.3 (Cavity Ventilation and Drainage) of the BCA requires that "Open perpendicular joints (weepholes) must be created in the course immediately above any damp-proof course or flashing".

I think the problem IS ingress. Weep holes won't in my opinion help. Penetrant sealer only... but don't use a membrane type sealer they breakdown via abrasion and UV damage... Though most likely the issues are on the southern side so will get minimal sunlight... still don't recommend them as they are subject to movement and this will 'break' the seal.

Though most likely the issues are on the southern side so will get minimal sunlight... still don't recommend them as they are subject to movement and this will 'break' the seal. So onc, what's Penetrant sealer (I mean brand name if possible ) and where do you apply it (to internal bare brick wall or external, or elsewhere)???? When you say "still don't recommend them as they are subject to movement and this will 'break' the seal", do you mean the weep holes or the "membrane type sealer"?
