"The conservatory had been installed on foundations but it was reported that the foundations hadn’t been laid in the right place and as a result it had undergone underpinning repair," says ABC Anchors director Richard Robinson. "This proved unsuccessful partly because the foundations had broken a drain and partly due to the excessive weight of the concrete."
ABC Anchors investigated the site with its hand-held soil probe and carried out a CCTV examination of the drains. Once the drain had been sleeved, seven screw piles were installed and grouted into place over a three days.
The hydraulic driver makes it possible to drive 3m or longer screw piles without using extensions, saving time and money.
