Steel bearing piles are an ideal pile solution when foundations are required for complex structures or difficult ground conditions exist.
They are ideally suited to hard driving through difficult ground conditions (e.g. silty, fine, water bearing sands containing cobbles and boulders or dense sands/glacial till) and are particularly viable and offer a cost effective solution when founded on rock or a similar hard strata.
Universal Bearing Piles are traditionally installed as bridge abutment foundations on heavy industrial and port developments or indeed any construction application where a high capacity driven pile solutions is acceptable. Bearing piles offer an extremely environmentally responsible solution since they are a low displacement pile which generates no spoils arisings and the can be extracted and reused upon decommissioning of the structure. UBP’s are generally installed using a vibratory hammer with a final drive to level/set using a hydraulic impact hammer.
Once installed, the bearing piles can be tested using ‘non-destructive’ pile testing methods to verify pile design axial capacity resistance has been achieved thus allowing immediate commencement of remaining foundation/substructure works.
Universal Bearing Piles are also used in ‘King Post’ or ‘Berlin Wall’ retaining wall solutions. Suitable in hard soil or bedrock conditions, a ‘King Post’ wall is formed by drilling a hole at defined centres, filling it with concrete and installing a UBP/UC section between which timber sleepers or concrete/steel panels can be installed in the steel section webs.
