Recently inspected house in the western suburbs showing concrete packing fitted to top of all of the concrete stumps. Reasons for packing are either from movement after the original construction of the house or the stumps were incorrectly fitted when originally fitted (very unlikely with this era of house), neither are good. If they were incorrectly fitted this indicates very poor building practice from the outset. If they were packed after the house was built due to movement then the chances of further movement occurring are far greater than it not occurring. The only way to guarantee against further movement is to replace ALL THE STUMPS with new ones at the same time. Unsavory as this may seem it is the only way to avoid further movement, this must be done before carrying out ANY ALTERATIONS, RENOVATIONS, EVEN PAINTING as cracking is very likely to occur with further movement!
