Sedro Woolley Horse Ranch 230kV, WA

Wilson drilled 31 shaft footings that ranged from 3 feet to 9 feet in diameter and up to 60 feet deep during this extremely environmentally sensitive project that included a right-of-way with difficult-access areas.

We installed casing and slurry displacement with tremied concrete placement and rock drilling with pre-blasting as approaches essential to completing the work.
