Notes: 1) It is important that the existence of underground services is clearly researched, and a location / identification procedure undertaken prior to commencement of piling. 2) Piles are installed using individual lengths of ERW steel tubes that are prefabricated to allow additional tubes to be added as necessary. 3) The initial tube is formed with a pointed end (the starter) into which a dry concrete mix is placed (the driving plug). 4) The Grundomat piling machine, which is a pneumatically operated, self contained reciprocating hammer, is placed inside the starter tube and drives the concrete plug, starter tube and subsequent tubes into the ground. 5) Additional tubes are added and electrically welded to the preceding tubes as necessary until the starter tube achieves sufficient resistance at its driving end. The exact resistance required is calculated by a formula and is measured on site as millimetres movement per seconds of time ("the piling set"). 6) The piles will be concreted by direct discharge from the pile head with a high workability, self-compacting mix.
