HI-TECH Rockfall is back at the site on I-90 in Washington State to complete another section of the flexible snow net structures in order to control avalanches on I-90. The work this year continues on a very unstable slope called slide curve which has very difficult drilling conditions due to access limitations and lots of talus material on the slope. HI-TECH is installing 4 meter and 3.0 meter high avalanche barriers at several locations across the slope. We expect to be complete sometime in October with this section.
