Driven piles are structural columns that are driven into the ground to form foundation structures. Interdrill’s piling rigs for driving piles are attached to a standard excavator, which allows us to work on challenging sites and those with difficult or limited access.

Piling Services Include:

• Timber piles from 150-450 SED H5 treated piles
• Steel piles – universal columns and steel pipe
• Concrete piles – pre-cast and pre-stressed
• Piling for retaining walls
• Bored and cast in situ piles
• Residential and commercial piling solutions

Ground anchors are utilised in a number of ways to give strength to new or existing structures. A small diameter bar or tendon is drilled through the face of the wall and anchored into stronger material remote from the structure. The strength is then spread across the structure using a capping beam or ‘waler’ that incorporates the anchor heads along the wall.

Increasingly, due to age, poor workmanship, repair or changing ground conditions, existing structures are being assessed as either outside their design life, or even on the brink of collapse. Interdrill can install ground anchors into these structures to offer immediate support and extend design life.

Anchoring Systems Include:

• Earthquake strengthening
• Drilling of ground anchors
• Assembly of ground anchors
• Installation of ground anchors
• Soil nails
• Retaining walls

Our drilling rigs are capable of drilling vertically or at any angle to a retaining wall and restructed access drilling rigs can be used in tight corners. Access problems are dealt with safely, with purpose built drilling rigs and suitable scaffold platforms to drill, assemble and install anchors.
