Why you might need a rotary piling rig
Rotary bored piles can support heavy loads, overcome underground obstructions, penetrate ground too hard to bore using a CFA and bore piles with a cut-off level beneath the platform.
How rotary rigs work
Rotary bores drill to a designed depth, using an auger, drilling bucket or core barrels which support the pile through any unstable ground, and are reinforced with concrete once the required depth is reached
