N2W2 Concrete Step
Barrier is the Highways Agency's preferred system for central reserve
vehicle containment.
We can
slipform various V channel profiles and can also include the trimming of
the sub-base simultaneously. Slot drains are a faster, more economical
solution to pre-cast units and our in-house fabrication team can advise on
mould construction to include integral kerbing.
In recent
years the traditional kerb laying process has been changed due to the HSE
enforcing stricter manual handling regulations. It is now the norm to see
kerbs lifted into place using vacuum grabs on fork lifts or excavators.
This has lead to a significant increase in cost with a reduction in output
making slipforming kerbs a viable option. Due to the linear nature of kerb
laying the slipform process lends itself to the task in hand. The mould on
the paver can be constructed to form any kerb profile from bull nose kerbs
to trief kerbs each being formed with a backing as the kerb is formed. This
completes the process in one operation saving time and as the backing is
formed with the mould there is no wastage of material. Output for
slipforming kerbs will vary depending on the kerb profile being formed
however a linear run in excess of 400m could be easily achieved in a single
shift.
