Piling - Bottom Driven Permanent Steel Cased Cast In-Situ
GeMech operate a fleet of Vermeer HL1000,
HL1200 and HL2500 piling machines. Manufactured in the Netherlands,
these machines are ideal for operating in residential areas where
space is at a premium and factors such as muck-away and contaminants
are important considerations.
With a selection of hammer weights, piles can be constructed
with working loads ranging from 5 tonnes to 85 tonnes. Unlike
conventional driven piles, these piles are bottom driven such
that all the energy is delivered directly to the pile toe (as
opposed to top driven where the energy dissipates down the shaft
of the pile) making the system extremely efficient and enabling
high capacity piles to be installed using relatively small piling
machines. The noise and vibration associated with top driven
piles is virtually eliminated.
The continuous steel casing ensures that no spoil enters the
pile bore and enables the cast in-situ pile to be constructed
as a whole monolithic pile without joints or glues as is
often necessary with pre-cast systems. There is no costly
breaking down of piles because the pile casing can be driven
to a pre-defined level and concrete placed within the casing
to approximate level of the RC works.
As all machines are under the 15 tonne threshold, there is no
requirement for a designed piling mat. Inexpensive to mobilise
and far less disruptive than full sized piling equipment, our
Vermeer range of driven piling machines obtain high output
at prices which compare favourably with alternative methods.
