Bored Piles

Continuous Flight Auger (CFA) piles are cast-in-situ concrete piles constructed by drilling into the ground using a continuous auger that prevents soil collapse during excavation. Once the desired depth is reached, concrete is pumped through the hollow stem of the auger as it is gradually withdrawn, forming the pile without the need for open excavation. Reinforcement is then inserted into the fresh concrete to complete the pile.

CFA piling is a fast, efficient, and low-vibration method ideal for urban environments and sensitive areas. It provides excellent load-bearing capacity and is suitable for a wide range of soil conditions.

The Double Head Drilling Method, also known as the Twin Rotary Head system, is an advanced piling technique that uses two independently driven rotary heads rotating in opposite directions. This counter-rotation allows simultaneous drilling and casing installation, ensuring excellent verticality, stability, and precision even in difficult ground conditions.

The method minimises vibration and ground disturbance, making it ideal for use in urban areas and near existing structures. It provides high-quality, continuous pile shafts and is suitable for a variety of soil types, including loose or unstable formations.

Full Displacement Piles (FDP) are cast-in-situ concrete piles installed using a specially designed displacement auger that laterally compacts the soil instead of removing it. During drilling, the soil is displaced outward, increasing ground density and improving load-bearing capacity. Once the required depth is reached, concrete is pumped through the hollow stem of the auger as it is withdrawn, and reinforcement is inserted into the fresh concrete.

This method produces minimal spoil, low noise, and vibration, making it environmentally friendly and ideal for use in confined or urban areas. FDPs provide high structural performance and are suitable for a wide range of soil conditions.

Helical piles, also known as screw piles, are pre-engineered steel foundations installed by rotating them into the ground using hydraulic torque. The piles have helical plates along their shaft that transfer structural loads efficiently to the soil while providing immediate load-bearing capacity.

This method is fast, clean, and low-vibration, making it ideal for urban sites, restricted areas, and locations where minimal soil disturbance is required. Helical piles are suitable for both temporary and permanent foundations and can be used for a variety of structures, including buildings, bridges, and retaining walls.
