Also... when you had the path/concrete redone, did you pay specific attention to the fall of the ground UNDER the concrete too? If that wasn't graded correctly water could be running off the concrete and then back under it towards the house. I'm pretty sure Matt cornellengineers mentions this in one of his super informative youtube videos. I've had a similar thought...I'll have to play around with that! I've got a spot next to the driveway which retains water and I'm going to install some drainage there to get rid of the water. Thanks for the confirmation. Re: Water ingress through brick wall into garage 12Dec 30, 2021 9:50 pm SaveH2O There appears to be a gap between the wall and the incorrectly sloped path. The top of the space filler should have been waterproofed. Is it? Water can also seep through bricks. Sorry, I'm not sure I understand? There isn't an incorrectly sloped path any more. Where is the gap you speak of? I've heard that bricks can have water pass through them, what can be done about that? Waterproofing paint? Re: Water ingress through brick wall into garage 13Dec 30, 2021 9:54 pm SLABsense What groundzero said. Check the neighbours and surrounding area. What's the surrounding ground/landscaping like? Where are the water sources located in proximity to the flooding? How is the ground sloping towards the house? If you can feel water inside the wall cavity, maybe investigate if the water source is further along the wall than where you're looking now? It could be running along the wall until it finds a way out and into your garage? If you're dead sure it all stops when it's not raining and gets worse when it rains then thats a great start! Go back to basics and map the flow of water from the cloud and covering a 20m radius of your house. Identify all the places it's caught, runs and is taken away. If you need some moisture sensors to bury around your house to log levels and rainfall over time let me know, we have rental units. (hope the shameful but helpful plug is allowed). I hope you track it down. Thanks for the detailed response! I live on an acreage, down a hill near a creek. I know water flows towards my house but for the most part it goes around the house (only severe storms does it build up and I'm working on that too). Yeah, the garage and the surrounding concrete dries up when there isn't any rain. I've got to move things around in the garage and strip that wall of plasterboard anyway (remove mould) so I might bump that up the priority list and potentially get a very good idea where the water comes in.

Where is the gap you speak of? I've heard that bricks can have water pass through them, what can be done about that? Waterproofing paint? as per H20, wind drive rain hits the wall and runs down it. Between the path and the slab there is usually some bitumen impregnated tape that acts as a cushion between the path and the house. It prevents direct contact. That is the gap i suspect that's being referred to. That tape has a removable top part, which needs to be removed and the gap filled with flexible sealant (like Sikaflex). Otherwise, wind driven rain running down the wall will make its way between the path and house gap. To what degree depends on how wide the gap is. water is invasive. Most people don't give it a second thought until its doing damage. The damage can be quick and absolute if not dealt with. Keep investigating. You may even need to cut some plaster out of walls to see if you can investigate the source of ingress. Dark matter scientist, can breathe underwater, mind reader and can freeze matter just by willing it. Trust me, its in my sig. Re: Water ingress through brick wall into garage 15Dec 31, 2021 1:11 pm TheBlackMini There isn't an incorrectly sloped path any more. I thought that the second photo indicated water was still pooling. NVM. You really need to spend a few dollars and have someone knowledgeable in the art on site as water leaks are tricky at the best of times. The first thing I would check is the concrete's height for compliance and while it is hard to tell from the photos, it still doesn't look right to me and seepage routes through the wall have already been established by the water. Finished surface height compliance varies between States and regions, are you in a low intensity rain area? 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.
