Flood proofing - need options

2 years ago

I have a house that was affected by overland flow flash flooding in 2022. Its the first time the house has ever been affected. The flood came up and went down within 90 minutes


- with no warning whatsoever. Flood was just under 1m high. The insurance builder wasnt keen to do anything but put it back together how it was, so thats been done. I have approval from Qld Govt for some funds to do remedial work and I want to explore dry proofing. There are 3 areas - the garage door, bi-fold doors at the rear (opening about 2.8m) and the frame where it sits on the slab. I’ve come up with (a) replace garage door with flood proof door, (b) seal the frame to the slab and (c) bifold doors - i dont know. The area needs light, so it needs to be clear. Flood proof doors would need to be kept closed constantly during rain so the dog cant get out to the yard. The remedy needs to be passive due to no warning. Some sort of pop-up barrier? Does anyone have ideas? The govt has list of potential builders but i need the step before to work out what’s possible
