Currently renovating a 1980's brick veneer in Scoresby, Melbourne (highly reactive clay soil) and have been paying attention to the brickwork since purchasing the home which has been getting considerably worse in particular at the front of the home. The bricks seemed to have broken apart under the window (weakest point) and started falling + sinking at the corner of the house. This has created a 25-30mm gap down the side of the window which has also led to the eave lining pushing the fascia boards out also to the point where it has opened right up in the corner. Ideally I don't want to get it underpinned (probably around $8k?) but are there any other option to stop the brickwork and foundations dropping? I think excess water build up and lack of drainage at the corner of the house has led to the movement in the foundations as the corner down pipe had a large hole for probably 5+ years and previous owner did nothing about it therefor the ground would have been expanding and contracting more than it should have. I cheaply patched the downpipe temporarily (replacing shortly) when I moved in and since then the brickwork has moved another 10mm approx. Trying to weigh up how much I spend on fixing the place or wether I leave as is and knock down in 5-8 years and lease in the meantime. Being a cheaply built home home im feeling it may be a better option to knock down in time rather than spend a bunch on it. Anyone had any similar movement in foundations/brickwork and have any advice that helped slow or even stop the problem. Cheers!
