guys i live in a 60 year old house, that was built on a fault line in the foothills, in adelaide fringe suburbs. my house is definately in the category of knock down and start again. it only has a footing (as opposed to a proper slab) and the 'back bone' is well and truly broken on it. well cracks in the walls, ceilings, cornices, outside walls are everyday fact of life in 'pre concrete reinforced slab' days. well i got sick of looking at all the new cracks appearing so i decided to stop using plaster (and choke to death with all the dust and mess) and just use silicone gap fill to fill up the never ending gaps appearing. i bought 4 tubes of it, to use with silicone gun, and that was not enough..... do you have any horror house stories to tell?
