Auger Bored & Drilled Piles
Bored piles are generally used in conditions where driven piles are unsuitable i.e. clay heave/shrinkage situations or where tensile loads are to be accommodated within the piles.
Our drilling rigs can also be adopted for down the hole hammer drilling to allow piles to be socketed into rock strata or for pre-drilling through obstructions.
Optima Foundations Limited offer a range of bored piles from 100mm up to 300mm in diameter.
Safe working loads are dependent on the nature of the bearing strata into which the piles are founded.
Our drilling rigs have been exclusively manufactured for us to suit our individual requirements and are particularly suited for working inside domestic properties in low headroom and tight access situations.All of our rigs can fit through a standard doorway and work within limited headroom.
