liner as well as a layer of its geosynthetic clay liner and drainage geonet,
which helped the power provider to
achieve this goal."

More Innovation
One of the more expensive aspects of
geosynthetic liner system installations is the need to seam the sheets
together. To help reduce this cost,
GSE has come up with a 34-1/2-footwidth membrane - the widest in the
industry - which reduces the seams by
50 percent. "Considering the industry
standard width is 22 feet, this helps
our clients greatly," Nigh asserts.
"Also, because seams can be a source
of leaks, this is a huge step in quality."
GSE was also the first to market
membranes with textured surfaces,
and has since made significant strides
in this area. Various soil types and

applications may require a membrane
with more texture to accommodate
sloped applications. "We can customize our manufacturing process to
add more texture to a liner, depending
on the client's slope and frictional
requirements," Nigh says. He adds
that GSE is the only company that has
developed liner systems with shear
strengths to meet the demands of projects in areas with high seismic activity.
Of course, the systems are only as
good as the raw materials used to
manufacture the products. Nigh says
that its researchers also collaborate
with suppliers to ensure the best
polyethylene formulations are used.
"Because we work so closely with
suppliers, we are able to find the best
raw materials available," Nigh notes.
Coal ash containment systems are
an emerging market for the firm.

South

"Working with the Ohio State engineering department, GSE has developed a drainage layer that is specifically designed for the fine texture of
coal ash," Nigh says. "Due to extensive testing, we've proven that our
drainage composites will not plug up
over time." He adds that this system
is offered exclusively by GSE.
Nigh attests that these strides
haven't been easy. "We're presented
with difficult challenges," he says.
However, collaborative efforts with
clients, rigorous testing and continual research have helped GSE, as well
as the industry, move forward. mt
