Envirochannel 100% recycled and
recyclable heavy duty drainage system installed at Polmadie
Strategic Maintenance Depot, Glasgow
Client: Transport Scotland
Main Contractor: BEAR Scotland
Civils Contractor: John Paul Construction
Specific Project Requirements
All the companies involved in this project demonstrate a
desire to use recycled and/or environmentally friendly
materials/methods of construction wherever possible. As such PDS
were approached to offer an alternative with a brief that the
system should provide;
1 - Material and installation cost saving.
2 - No compromise to design, performance in terms of
hydraulics, load performance, maintenance issues and
3 - Full Compliance.
The primary functions for any drainage system are to efficiently
collect and discharge run-off from structures. For this project
there were additional considerations such as containment in the
bunded areas and likely corrosive contaminants within the run-off.
The large reinforced slab would also deliver large volumes of
rainfall so our proposals had first to be backed with full
hydraulic calcs with notes relevant to each run and its particular
Having satisfied all the project's requirement the material was
supplied to site in July 2012 and installed within six weeks.

'We will always look
at greener alternatives wherever we can however on projects like
this we cannot accept any compromise on quality. PDS delivered a
cost effective system of drainage that was lightweight and easy to
install yet very robust. Across the whole site there were zero
It terms of function, over the past few weeks we have had
record rainfalls falling almost continuously across the whole
completed and exposed slab area (10,400m2). The channel has taken
the run-off and dealt with it. We will certainly be looking to use
this product again.'
As a solid one piece unit with tensile strength the Envirochannel
keys into the structure well. Unlike traditional grated systems,
there is no surface load transfer point from grate to channel body
and unlike slot systems it provides a reduced installation depth.
Supplied in 500mm lengths it is possible to follow a low point
across any surface whether splayed, cornered or curved.
Envirochannel has the strength to cope
with all loads experienced on site during the construction
Enviochannel has many demonstrated proofs
of performance within heavy duty environmnets across the UK,
Ireland & Europe.
