Weep holes are only required for cavity walls to allow moisture that may get into the cavity room to escape. The cavity ensures that moisture doesn't get into the internal brickwork, and everything that crosses the cavity, eg windows and doors, are designed to ensure that moisture doesn't come into contact with the internal leaf. As a garage isn't considered a "habitable" room it only has a single leaf of brickwork meaning that damp can penetrate through the external wall. However if you did render a double brick wall you can simply drill a hole with a large 10mm masonry drill bit below the level of the concrete inside the house. The hole needs to go all the way through the brick to the cavity every 1200mm. This will be enough to ensure the moisture is able to escape. I hope this helps. Hi there, long-time lurker but first time posting. I've bought a house 2 and a bit years ago and last year we had some major water damage on a converted pergola area… 0 7929 Yes, unless you are in a low intensity rainfall area or the area is protected from rain. Do you have access to NCC Part 2 or can you download it? I can email you a copy… 10 12506 Thankyou so much 😀 I've decided on White on white for doors and trims, White on white 50% on ceiling and Mt buller for walls. Fingers crossed it will look OK 😀 2 7157 |
