Linkbelt 98 with lead attachment and vibratory hammer shown in front.

The Anchor Group own a selection of vibratory hammers. A vibratory hammer is mounted on a service crane. The vibratory hammer is connected to the top of the steel liner with "steel jaws". This temporary liner is vibrated through the non-cohesive material into a cohesive soil below to provide a seal. The larger hammers are capable of advancing liners into weathered shale or dense tills.
