Olympia Sewer Trestle

The city of Olympia, WA had a problem. The slopes around a Sewer Main trestle foundations were eroding. The previous trestle had broken and it was an, 'O CRAP' moment. The new trestle had been constructed, but the slopes around the foundations were not stable. Enter the Hilfiker Spiralnail Welded Wire slope stabilizing solution. A crane hung the spiralnail hammer and it was a versatile hammering machine in all the hard to get to places.
