World Trade Center / Ground Zero

Following the disasterous events of 9-11 and the subsequent cleanup it was decided to use the site to memorialize the event.


In order to create this, huge amounts of excavation and repair were needed.  Our part in this was the sealing of the main Slurry Wall between the site and the Hudson River.  Using our Hyperflex water activated grout and our SealGuard II water control system.


Although time constraints were tight for the construction schedule, we were able to synchronize our efforts and results to give a dry project on time.
