traditional methods such as a slurry wall
were initially considered for construction, engineers ultimately chose to install
more than 600 linear feet (183 m) of
SG-525 PVC sheet pile for containment.
Beginning in August 2007, the PVC sheet
piles were installed without any sealant
in the locks to a depth of 17 feet (5 m)
(Figure 6). The sheets were installed into
soils with blow counts in excess of 50
using a steel mandrel system. Engineers
checked the groundwater post-installation of the sheet pile system through the
use of monitoring wells on a quarterly
basis. The sheet pile wall was effective
in containing the flow of contaminants
from the site (EPA 2008).

Elementis, Texas
The groundwater and soils at this
Corpus Christi, Texas, manufacturing plant became contaminated with
high concentrations of benzene due to
operations at El Paso Merchant EnergyPetroleum petroleum plant. Engineers
were tasked with developing a cutoff
wall solution that had a high resistance
to degradation and minimized excavation and ground disturbance. The
engineers working on the project specified SG-625 PVC sheet piling manufactured using coextrusion technology and
hydrophilic sealant to be used in the
interlocks to create an all but impermeable barrier. The SG-625 profile is
