150mm diameter driven cased piles are the most comman piles that we install. There load capability is 80 - 100KN dependant on ground conditions. We use this size of pile for all types of underpinning, reinforced ground beams and slabs. The pile casings range from 1.0m to 2.0m sections enabling use in restricted head room situations and to be manually handled through doorways or into cellars.
The piles are driven internally with a grundomat (shown across in Black + White) or with a Drop Hammer Rig.The grundomat is powered by compressed air. Our compressors can be located outside and air lines run inside thus preventing any build up of fumes and minimising distruption. The Drop Hammer Rigs are powered by a silenced diesel power pack and runs off hydraulic lines (shown across)
The following is how the grundomat system drives the pile:
