Vibro Concrete Columns

The Keller Vibro Concrete Column (VCC) piling system provides a quiet, economical, mess-free piling solution for sites underlain by weak alluvial or organic deposits such as peat and soft clays.

Extremely quiet with low vibration, the Keller VCC piling system is an environmentally acceptable alternative to driven precast or cast insitu systems. Vibro Concrete Columns are constructed with enlarged bases and designed to develop the full potential of the founding strata.

The purpose-built Keller Vibrocat piling rig is stabilised by hydraulic outriggers and the guide leaders positioned for verticality/tremmie system is connected to a powerful mobile concrete pump. The vibrator is charged with concrete and pushed down to the bearing stratum.

The vibrator is lifted and re-inserted to form a bulb and then carefully removed while pumping concrete.  Once completed, the columns can be trimmed and reinforcement placed as required. 

Highly Efficient

VCCs are ideal for weak alluvial soils such as peats and soft clays overlying competent founding stratum such as sands and gravels, soft rocks etc. Working loads up to 750kN can be achieved in appropriate soils.The "bulb end" and frictional components of the VCCs enable high safe working loads to be developed at much shallower depths than alternative piling systems and thus generally provide a far more economical solution.

Rapid Installation

Programme benefits can be gained from the highly efficient VCC construction process which can produce over 1,000 metres of concrete column per rig week.

The VCC system is a quiet low vibration-displacement process with none of the mess and high cost of spoil removal associated with continuous flight auger and bored piling systems.
