The Project

Winter’s rains (2016 to 2017) caused significant problems on the coastal highway. Officials said there were 17 storm-related work sites in Marin, most of those on Highway 1, as rainwater cracked roads and undermined road beds.

For re-construction works, anchors needed to be installed for slope stabilization and to prevent the highway from washing away again. The construction company was averaging approx. two holes per day with two machines. Using one Hutte 605, the company averages 2-3 holes per day!
