An offsite solution

摘要

Compared to traditional in situ construction methods, offsite manufactured circular concrete manhole systems are quicker and cheaper to install, create less waste and, most important of all, they help improve safety on site. In fact, a circular precast concrete manhole system has the potential to cut installation time on site by up to 50 per cent and to reduce installed costs by 15 to 30 per cent, particularly when manholes are installed without a concrete surround.
