Simplex Westpile has long been renowned for its expertise in Rotary and CFA Piling and its innovative approach to the design and construction of retaining walls.
Rotary bored techniques:
- Offer a larger range of pile diameters and depths than any other piling method
- Permit pile construction through particularly stiff or hard strata
- Offer concrete placement to below commencing surface level
- Can permit inspection of the pile during construction
Our fleet of rigs contains both traditional crane mounted and hydraulic rigs which have the capability to install piles from 350mm to 2.4m in diameter.
Crane mounted rigs reach far in front of the rig and are most suited to sites where short casings can be used and speed is a primary driver. They can be a better solution inside propped basements due to their ability to reach over raking props.
Modern hydraulic rigs are powerful enough to screw in longer lengths of pile casings and rely less on vibratory hammers.
With these techniques, as well as any natural soil conditions, we can overcome many man made obstructions that would otherwise have to be removed prior to piling.
Technique:
Construction methods depend greatly on the geology of the site. Piles are cased through upper soft strata and are then excavated as open holes in stable ground below. Where no stable ground exists drilling fluids can be used to negate a requirement for long temporary casings.
Reinforcement is placed prior to concrete being poured to the required level and the casing withdrawn.
