FAQs

Piling and Foundation Services – Common Questions

Aldig installs bored piers, CFA (continuous flight auger) piles, soldier piles, secant pile walls, contiguous piles and underpinning. We select the best method based on site size, soil type, and structural requirements to ensure safe and reliable foundations.
Piling transfers building loads to deeper soil or rock, bypassing weak surface soils. This is essential for stability on sites with poor ground conditions or where close boundaries require precision and minimal movement.
Bored piers involve drilling holes and pouring concrete, while CFA piling uses a continuous auger with concrete pumped as the auger is withdrawn. CFA is often faster and creates less vibration, ideal for sensitive or urban sites

Absolutely. Aldig’s piling rigs are utilised by experienced fully licensed operators and our baby drill rig is able to negotiate bluestone laneways and fit through doorway and garage openings only 1.0 meter wide and 2.1 meters high with ease.

Piling is a foundation technique used to support structures by driving reinforced concrete or steel piles deep into the ground. In basement construction, piling is often required when soil conditions are weak, building underground or when neighbouring structures need support during excavation.

Piling ensures your basement is stable and secure. It helps retain soil during deep excavations, prevents structural movement, and supports heavy loads from above-ground structures. Our expert piling contractors in Melbourne design piling systems tailored to your site conditions.

The most common piling methods for Melbourne basements include bored piles and continuous flight auger (CFA) piles. The right method depends on soil type, excavation depth, and access to your site.

Not all basements require piling. It depends on soil stability, water table levels, and proximity to neighbouring buildings. Our basement specialists in Melbourne assess each site to determine if piling is necessary.

A DCP (Dynamic Cone Penetrometer) Test measures soil strength and compaction. It is used in basement construction to determine soil bearing capacity and to guide foundation design. This ensures that footings, slabs, and piles are constructed on a stable base.

A piling rig platform is a temporary working surface created to support heavy piling equipment during basement construction. It ensures the rig operates safely and effectively while drilling piles into soil or rock. Piling and foundation working platforms are mandated under Victorian occupational health and safety (OHS) laws.
Yes, a geotechnical report is essential. It provides detailed information about soil conditions, rock layers, and groundwater levels. This data is used by engineers to design safe foundations, retaining walls, and waterproofing systems for basements in Melbourne.
Piles come in a wide range of diameters, typically from 300mm to over 1200mm, depending on the project requirements. The pile size is chosen based on soil conditions, load requirements, and structural design. The pile design will change depending on the requirements of the basement or concrete structure.
Yes, most piles built to support a structure require reinforcement with steel cages or bars. Reinforcement strengthens the pile, improves load-bearing capacity, and ensures long-term durability in varying ground conditions. Mass concrete piles can also be included in a residential design in Melbourne usually to support strip footings or raft slabs.
Pile depth varies depending on soil and load conditions. In Melbourne, piles may range from a few metres to over 20 metres deep, with some projects requiring even deeper foundations to reach stable rock or load-bearing strata.

Common pile types include:

  • Bored piles (drilled and filled with reinforced concrete)
  • Driven piles (precast and hammered into place)
  • Screw piles (steel piles twisted into the soil)
  • Secant piles (Overlaping piles creating an interlocking wall)
  • Contiguous piles (placed side-by-side creating a continuous barrier)
  • Sheet piles (used for retaining walls and excavation support)

The type of pile depends on the basement design and soil profile.

Yes, piles can be drilled into rock using specialised drilling equipment. This ensures secure anchoring and strong foundation support for basements and multi-level concrete structures.
Yes, piles can be drilled into sand, though it requires casing or stabilising techniques to prevent collapse during drilling. Reinforced concrete piles are commonly used in sandy soils around Melbourne. Aldig own a specialist CFA piling rig which can drill into more complex materials that can’t be done with a regular piling rig.
Yes, piles can be drilled in waterlogged ground or below the water table using techniques such as slurry, casings, or drilling fluids. This allows basements and foundations to be built even in challenging wet conditions.

Common footing types include:

  • Strip footings – continuous footings beneath walls.
  • Pad footings – isolated footings under columns.
  • Raft slabs – slabs covering the entire footprint.
  • Pile footings – deep foundations transferring loads to stable strata.

The right footing type depends on soil conditions, basement depth, and structural design.
