Ground conditions and drainage in Schofields NSW
Schofields sits on the Cumberland Plain, where soils weather from Wianamatta Group shale into clay rich profiles that swell and shrink with moisture. The practical consequence for an owner is not the geology, it is the drainage. On one Schofields property we found a downpipe that had never been connected to the stormwater system, which means every rain event for years had been discharging roof water at the base of a wall, into exactly the clay that responds worst to it. We publish no site class for the suburb, because that belongs to your lot's soil report.
