A bored pile is a cast-in-place concrete pile, meaning the pile is cast on the construction site. This differs from other concrete pile foundations, like spun pile and reinforced concrete square pile foundations, which use precast concrete piles.
A Bored Pile is a non-displacement form of foundation that is cast in situ and provides economical load bearing and walling solutions suited to a wide range of ground conditions and applications. Key advantages include
Able to carry very high load / shear / moment capacity
Low noise and vibration
Ground is “seen” during construction allowing validation of design assumptions
Able to carry very high load / shear / moment capacity
Low noise and vibration
Ground is “seen” during construction allowing validation of design assumptions
Can overcome adverse ground including natural or manmade obstructions
Can drill into hard rock
Can be constructed to tight tolerances
Bored piles can be constructed using crane mounted or track mounted hydraulic drill rigs. The excavation for bored piles can be supported using casing installed by vibrators or oscillators and by drilling muds. Piling Contractors offers the following advantages for construction of Bored Piles:
Wide range of drill rigs available (rotary, crane-mount, excavator mount, low headroom);
Reliability of personnel, plant and equipment to provide a quality product
A proven track record of experience and knowledge across all areas of Australia gained during more than 25 years of constructing bored piles
Economical and productive methods of drilling in all ground conditions, from soft soils to very high strength rock;
Extensive range of drill tools, casings and other auxiliary equipment suited to different drilling conditions that may be encountered;
Localised plant and equipment support in capital cities around Singapore and Malaysia
As heavy foundations, securing deep excavation especially close to existing buildings as well as stabilising and retaining slopes
In a variety of infrastructure projects such as highway, road or bridge construction as well as flood protection
Retain ground alongside an excavation pit or close to adjacent buildings, often combined with other techniques such as ground anchors or soil nails
For slope stabilization to prevent landslides, or protect existing buildings
