Drainage Pipes
Drainage of a landfill body requires the use of piping material that
meets special resistance requirements during the construction phase,
because the drainage pipes are in continuous contact with the
aggressive dissolved media. Once the landfill cell has been closed, no
water is expected to flow in; the drainage therefore acts as control
drainage and the pipes are exposed to concentrated amounts of
landfill leaching.
HDPE Pipes
The landfill leachate has to be transported from the outlet structures
to the treatment units in order to be treated. AGRU HDPE pipes of
the highest quality are used here to prevent contamination of the
environment.
Pipe Penetration
The combination of AGRU pipes, fittings, and sheets with our HDPE
and LLDPE geomembranes ensures that they all can be welded to the
landfill body permanently with stable, leak-proof joints. As a one-stop
system supplier, AGRU is able match the various components optimally
in terms of welding capability.
ClosureTurf®
ClosureTurf, a Watershed Geo patented product, is a final cover
system comprising AGRU’s Super Gripnet® or MicroSpike®
geomembrane overlain by an engineered synthetic turf and
specified infill material. It is a proven “hybrid” composite closure
system that outperforms earlier closure methodologies and is the
only system that provides a predictable level of performance when
subjected to severe weather conditions that occur in a post-closure
timeframe. Based on several years of real-world experience on over
900 acres of installation, and extensive university and ASTM lab
evaluations, the ClosureTurf system has shown to have a leakage
rate over 40 times less than Subtitle D prescriptive and an erosion
loss of over 100 times less than subtitle D prescriptive cover.
