New houses on shaky ground

NEW houses in Melbourne's west could be prone to severe building cracks because their foundations haven't been designed to cope with reactive soil, according to fresh legal claims.
Slater & Gordon is representing several homeowners in the north-western and western suburbs whose newly built houses are cracking and twisting.
Lawyer Robert Aurrichio blames a particular type of concrete slab foundation, known as a "waffle slab", claiming it's risky to use in the volatile soil conditions in the west.
"We've spoken to a number of experts who believe that [the waffle slab] needs to be designed with adequate drainage to cope with the variable nature of the soil in the western suburbs," he said.
Slater & Gordon client Noel Spooner says the foundations of his two-year-old Werribee home are breaking. His house is riddled with cracks in the plaster and cornices, and doors won't stay closed due to gaps emerging between door frame and jam. "I was peeved," Mr Spooner said. "Why did they not do the due diligence before building? It's ludicrous to just walk away and say it's bad luck, you're on reactive soil, and using that as a defence. These are people's life savings and their dream home could be uninhabitable."
Archicentre general manager David Hallett said waffle slabs had been widely used for more than a decade across Melbourne's western growth areas due to the high volume of new housing estates. "In suburbs like Caroline Springs, areas around Burnside, Tarneit, Werribee and Melton, the simple fact is that there's been thousands of these buildings built over the last decade and typically more and more have been with waffle slabs," he said.
But Mr Hallett disputed Slater & Gordon's claim that building cracking was related to a particular design of concrete slab foundation. He said foundations for any new building needed to be designed to suit the soil conditions of the site, as determined by soil tests, irrespective of whether they used waffle or flat slabs.

好像都是一些比较新的房子。打地基的时候没有考虑到土壤的变化。 造成一段时间以后地基沉降，房屋开裂。记得很早以前在point cook 看房， 有几家房子周围的散水和房子都脱离了， 可能是因为沉降。
