Large Diameter Auger (LDA)

Large Diameter Auger (LDA) piling is a widely used foundation technique designed to support heavy structural loads. This method involves drilling large diameter boreholes into the ground and filling them with reinforced concrete to create strong and stable piles.

Construction Method

LDA piles are constructed using advanced rotary drilling rigs equipped with augers. Depending on soil conditions, temporary casing or support fluids such as bentonite or polymer are used to maintain bore stability during drilling.

Pile diameters typically range from 500mm to over 1200mm, and depths can extend up to 60–70 meters based on design requirements.

Key Features

LDA piling provides high load-bearing capacity and is suitable for a wide range of soil and rock conditions. It allows flexibility in design and can be adapted to complex site requirements.

This method ensures strong foundation support for large-scale infrastructure and heavy structures.

Execution Process

The process begins with drilling the borehole to the required depth. Reinforcement cages are then lowered into the bore, followed by controlled concreting to form the pile.

Applications

LDA piles are commonly used in high-rise buildings, bridges, metro projects, and heavy infrastructure developments requiring deep and strong foundations.
