Balfour Beatty Ground Engineering (BBGE) has launched what it claims is the UK’s first precast pile cutting system, which it says can eliminate wastage.
The system works by cutting precast concrete piles above the ground with diamond tipped blades and using the trimmed section as the lead part of the next pile. The system, which has a patent pending, was developed with Finland-based Junttan, which supplied the mechanical cutting capabilities.
According to BBGE, the piles can be cut off to within 100mm of ground level to reduce obstructions for follow on trades without compromising compressive strength.
BBGE recently used the system on the foundations for a new supermarket in Scotland, where use of the system saved 3,600m of wasted pile on the 4,500 piles used on the scheme.
“We are committed to driving down waste and improving the efficiency of our service and this new technique for precast pile cutting is a highly effective way to do this,” says BBGE managing director Malcolm O’Sullivan.
