Grundomat Piling Hammer

Description	Benefits
·         Piles are installed using individual lengths of ERW steel tubes to be added as necessary.   ·         The initial tube is formed with a pointed end (the starter) into which a dry concrete mix is placed (the driving plug).   ·         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.   ·         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”)   ·         The piles will be concreted by direct discharge from the pile head with a high workability, self-compacting mix.	·         No “Spoil” above ground level; this eliminates the need for on site skips to remove soil etc.   ·         Ideally suited to buildings with limited access or minimal working space.   ·         Allows for access to locations that are inaccessible to excavators/mini diggers.   ·         Reduced noise, this reduces the local impact in sensitive locations.   ·         Can be used in wet and dry ground conditions.
Mini Piling Rig
·         The Rig is used to drill down to required depth up to approximately 20m if required with hole diameters ranging from 150mm – 350mm depending on site requirements.    ·         Spoil is taken from piling rig position to an onsite skip ready for disposal. (Spoil can be left onsite for ground fill if required).   ·         The bored hole is then filled with concrete ready for the steel reinforcement, this is achieved by either filling as the auger is removed (this method is particularly useful in poor or wet ground conditions) or by filling the bore hole after the auger is removed (this method is more cost effective)	·         Allows for increased loading and therefore allows for larger conservatories and extensions.   ·         Can be used in wet and dry ground conditions.   ·         Reduces the need for extra deep footings that can be time consuming and costly.
