Diameter ranges from 90mm to 400mm.
Avopiling utilises its Soilmec SM405 drilling rig to install anchors.
The same equipment is also utilised for large dia. bored piles. Avopiling have on a number of occasions used DTHH method to create pre bores in extremely high strength rock for a large dia. bored pile. This increases efficiency through rock sockets and also creates the opportunity to use a smaller rig when platform space is of concern.
