As part of their plans to improve transportation links in
the region, South Lanarkshire Council, in collaboration
with Strathclyde Partnership for Transport, funded the
development of a £2million Park & Ride facility at
Carluke Station, providing South Lanarkshire commuters
with an additional 329 spaces, including disabled
parking.
The 0.8 hectare Park & Ride facility is situated on the
west side of Carluke Station and due to the elevated
position of the station in relation to the park & ride
area, it was necessary to build appropriate pedestrian
links, including a DDA compliant pedestrian access ramp.
A key element of the design was the provision of an
engineered drainage system behind the access ramp
retaining walls. Inadequate drainage can result in a build
up of groundwater behind a retaining wall and this
‘trapped’ water exerts hydrostatic pressure which can
affect the structural integrity of the wall.
Following thorough investigation into various drainage
methods, civil engineers from South Lanarkshire
Council’s Roads and Transportation Services determined
that a Fin Drain system would be the most effective
solution for the Carluke Station Park & Ride access ramp.
Fin drains use prefabricated drainage composites in
conjunction with traditional granular backfill to collect
and help channel groundwater into the area’s main
drainage system. The robust characteristics of composite
materials ensure a highly sustainable solution that
operates extremely effectively during the design life of
the structure.
Geocomposites used in subsurface drainage applications
usually consist of a three-dimensional polymer core,
which acts as the water channel, coupled with geotextile
filters which allow water to pass into the core but
prevent soil from washing through, thereby helping
maintain soil stability.
For Carluke’s Park & Ride facility, South Lanarkshire
Council specified Terram’s 1BZ as the most suitable
drainage composite for the access ramp’s drainage
requirements.
Commenting on the project, Gordon MacKay, Head of
South Lanarkshire Council’s Roads and Transportation
Services said:
“We needed to ensure that the drainage system would
be sustainable, providing the retaining walls with
maximum protection from hydrostatic pressure
