Reinforced Concrete Piles

Spiral Drillers can construct drilled reinforced concrete piles up to 3.6m diametre, and to depths of up to 42m. Larger, deep piles are constructed using our fixed mast machines while our fleet of pendulum rigs are used for smaller projects.

Low headroom and tight access piles can be constructed using one of our micro rigs with capacity of up to 1.0m diametre to depths of up to 20m, site dependant.

Belled piles can be belled up to 3600mm diametre with a special belling tool.

Grooved piles are achieved using a special grooving tool to the project specification.

Boreholes can be supported by temporary or permanent casings (caissons) as per soil conditions. Casing for all diameters can be installed and advanced ahead of drilling works using our various vibratory hammers.

In wet soil with high ground water levels, drilling can done using mineral (bentonite) or polymer slurries. If the ground conditions are good but there is excessive ground water, tremmie pouring the concrete can be done to ensure a good quality pile.
