While prepping
the concrete surface for both tanks,
the crew scraped
off the existing
rubber tar membrane system and
then sandblasted the concrete surface using
crushed glass in an 18-inch curb going up the
steel wall.
“The purpose of applying the crushed glass up
the steel wall was to create a profile for the poly-
urea to grip and grab to,” said Passarella. “For
the concrete surface, the crushed glass blasting
cleared off all the debris and allowed us to get
a base, clear surface, which was necessary for a
smooth application.”
Seneca put their faith in Straight Line Contract-
ing for the tanks’ restoration, which entailed the
application of polyurea to the tanks’ compromised
concrete floors. Prior to their arrival, the tanks
were completely pumped to devoid them from any
moisture. Then, a three-man team from Straight
Line arrived at Seneca’s facility and went straight
to work.
“Polyurea was the correct choice for this particular
project,” said Straight Line’s Megan Passarella. “It
creates a seamless, self-adherent membrane that
can withstand the treatment process and last for a
long time versus other epoxy products that require
constant maintenance and reapplication. Seneca
was looking for a solution that would see those in
charge of this operation not having to worry well
after their retirement. We gave them that within a
short time frame, as the polyurea cures rapidly and
works effectively.”
