Construction Drilling Project

The Madrona Way road had a long history of sliding into the Puget Sound and was in danger of being closed for safety reasons. The Gregory Drilling team was called in to carefully stabilize the road while protecting the sensitive natural area next to the Puget Sound, surrounded by large trees and overhead power lines.

  Drilled 30 12-inch holes to 50 feet deep at a 45 degree angle through cobbles and boulders.
  Stabilizing micro-mini piles were constructed by inserting rebar, removing the well casing and backfilling with cement.
  Completed construction drilling project in 20 days.
