Vibro Displacement Stone Columns
GeMech is a specialist ground
improvement, piling and foundation contractor offering a wide
range of expertise and experience, making it possible to provide
our clients with cost effective tailored solutions to founding
problems.
Vibro displacement stone columns are a technically accepted
and economic method of enhancing fill material and weak soils
to improve their load bearing and settlement characteristics.
The construction process involves introducing a vibrating poker
or driving a vibrating mandrill to penetrate to a designed depth,
and then filling the resulting cavity with layers of inert stone
or recycled material in accordance with ICE specifications. The
vibrator is reintroduced to the cavity, forcing each layer of
stone into the surrounding ground creating confining pressure
and densified columns of support. In granular material this densification
creates an improvement in settlement control and bearing capacity.
In cohesive materials the overall effect is one of reinforcement
and settlement control.
The stone column layout can be arranged to suit varying combinations
of load, soil type and settlement requirement. This forms a raft
of stiffened material creating an integrated foundation support.
Typically column spacings range between 1.0 metre and 2.5 metres
under load bearing foundations and up to 3.0 metres beneath floor
slabs.
GeMech will design and construct the entire
building platform utilising a variety of ground improvement solutions
ranging from vibro displacement stone columns, dynamic compaction
(and consolidation), soil recycling and stabilisation, bored
or driven piles, reinforced concrete ground beams, suspended
concrete floors, ground bearing floors, blockwork up to DPC and
drainage within the footprint of the building.
Why take a chance. Insist upon a GeMech building
platform at a quality and price you will find hard to beat.
