Bored Piling
Australian Piling experts
Bored piles are commonly used as a foundation solution when the conditions of the ground are considered fair to good, i.e. there is; no threat of shallow water table, soils are cohesive or rock and spoil removal is not a problematic or costly trait (such as contaminated / asbestos or acid sulphates). Bored Piles drilled into rock conditions, enhance the chances of minimising any foundation settlement. Australian Bored Piling experts provide top-of-the-line bored piling services in Sydney and surrounding areas. We own various types of track-mounted drilling rigs and excavators which are capable and available to drill depths up to 30m into high-strength rock.
Bored Piles are drilled with circular augers, cleaned, and then filled with concrete and steel-reinforced cages. The Soil/Rock is removed using certain designed drilling tools, such as soil augers, rock drills, core barrels and clean-out buckets, which can reach a depth of up to 30m and range in diameter from 200mm OD to 1200mm OD. We have several methods available to support the walls/sides of the pile during its construction. This is assessed and selected according to the ground condition being drilled into i.e. soft soils, stiff clays or rock layers, the level of the groundwater found and the environmental constraints on site. In the case where a drilled hole requires intervention to remain open (before the soil/sand collapses the hole), we use a steel liner/casing which can be permanent or temporary.
Screw Piling Experts – Specialists in Deep Foundation Solutions
Bored piling is one of the most reliable and versatile foundation systems used across civil, commercial, residential and industrial construction. It is particularly effective when structures require high load capacity, minimal settlement risk, or resistance to multiple load cases such as uplift, tension, lateral forces and large bending moments. At Screw Piling Experts, we design and construct bored piles that meet stringent engineering requirements while delivering long-term stability and performance.
Bored piles are best suited to projects where the ground conditions are fair to strong, including sites with cohesive soils, stiff clays, shale or rock. They are also recommended when spoil removal is manageable and when groundwater is not a significant constraint. When drilled into competent rock, bored piles offer exceptional support and significantly reduce the likelihood of future foundation movement. With decades of experience and a fleet of specialised drilling equipment, Screw Piling Experts deliver high-quality bored piling installations throughout Sydney and surrounding regions.
Our Commitment to Quality and Engineering Excellence
At Screw Piling Experts, every bored pile installation is executed with precision, safety and technical oversight. We work closely with engineers, builders and geotechnical consultants to ensure each pile meets prescribed design loads and geotechnical conditions.
Our services include:
- Full engineering design and documentation
- Detailed pile logs and compliance reporting
- On-site management by experienced supervisors
- Installation using certified equipment and calibrated tools
- Adherence to Australian Standards and industry best practice
Our goal is to deliver a foundation system that performs reliably for the life of the structure.
Engineered Support for Every Ground Condition
Ground conditions can change rapidly within a single site, which is why we employ multiple strategies to stabilise the bore during drilling. Our team assesses soil type, groundwater level and environmental sensitivities before determining the most appropriate support method.
Depending on the conditions, we may use:
- Temporary or permanent steel casings to prevent collapse in soft soils or saturated ground
- Dry drilling techniques for stiff clays or rock where the bore remains naturally stable
- Specialised drilling tools to manage changes in strata and maintain structural accuracy
These methods ensure the integrity of the bore until reinforcement and concrete are placed—preventing collapse, contamination or displacement.
Why Choose Bored Piling?
Bored piles offer several advantages, making them a preferred choice for medium to large-scale structures, including:
- High capacity for vertical, lateral and moment loads
- Minimal vibration—suitable for sensitive environments and nearby structures
- Ability to drill deep into rock for exceptional stability
- Ideal for sites with limited headroom or access restrictions
- Flexibility to create customised diameters and reinforcement designs
Whether you’re constructing a multi-storey building, industrial facility, bridge abutment, retaining system or civil structure, bored piling provides a strong, durable and engineered foundation solution.
Advanced Drilling Capabilities for All Project Types
Our track-mounted drilling rigs and excavators are engineered for performance in diverse and challenging conditions. Equipped to drill depths of up to 20 metres into high-strength rock, our fleet allows us to construct bored piles across a wide range of project scales, from small residential builds to large industrial and civil developments.
Each bored pile is formed by drilling with circular augers, removing spoil, cleaning the shaft, and filling the excavation with steel reinforcement cages and high-grade concrete. We use a range of specialised drilling tools—including soil augers, rock augers, core barrels and clean-out buckets—to achieve precise depths and diameters from 200mm OD up to 1200mm OD. This ensures pile integrity, consistency and compliance with engineering specifications.
Frequently Asked Questions
Bored piling is typically recommended when a structure requires high load capacity, minimal settlement risk, or resistance to uplift, tension or lateral forces. It is also ideal for sites with cohesive soils, stiff clays or rock where spoil removal and groundwater conditions are manageable.
Our drilling rigs can reach depths up to 30 metres and construct pile diameters from 200mm OD to 1200mm OD. Depth and diameter are determined by engineering design, project requirements and ground conditions encountered during drilling.
We utilise specialised tools such as soil augers, rock augers, core barrels and clean-out buckets, allowing us to drill efficiently through soft soils, clays, mixed strata and high-strength rock. This ensures accuracy and stability throughout each stage of construction.
Depending on ground conditions and groundwater levels, we may install temporary or permanent steel casing or use dry drilling techniques where the soil naturally remains stable. Each method is selected after assessing on-site geotechnical conditions to ensure bore integrity.
Yes, but the approach depends on the severity of groundwater conditions. For shallow or manageable groundwater, we use casing or specific drilling methods to stabilise the bore. For sites with significant groundwater issues, alternative piling methods—such as screw piling—may be more efficient.
Bored piling is widely used for multi-storey buildings, commercial structures, industrial facilities, bridges, retaining walls, large footings and civil infrastructure. They are especially effective where deep foundations and high structural capacity are necessary.
