Bored piled foundations; diameter of piles: 150-350 mm
Hutte bored piling rigs capable of constructing 150-350 mm diameter piles are instrumental in underpinning works, as well as in construction of piled foundations using pile diameters of 200-350 mm with rigid tube reinforcement and Ichebeck micro-piles. Productivity - up to 250 l.m. of piles per working shift. Currently in the possession of the company there are 6 rigs: HBR-605 (diesel), HBR-609 and HBR-202,203 (diesel and electric).
Construction of bored (cast-in-situ) 400-1500 mm diameter piles for use in both new development and reconstruction projects
Franki rigs are capable of constructing screw piles with up to 820 mm diameter with output of up to 10-12 piles per working shift (100-200 l.m. of piles).
Currently in the possession of the company there are 5 Franki bored piling rigs BT50, 3 Fundex rigs and 5 Casagrande rigs .
Widely used methods:
- Atlas screw piles
- Fundex screw piles with sacrificial tip
- CFA (continuous flight auger) piles
