The objective was to replace the Harrison Avenue Bridge in Scranton, Pennsylvania, which was built in 1922 and had outlived its usefulness. 3C Drilling, LLC was contracted to drill (7) 96” diameter piers ranging in depth from 35’-55’ deep.

Five years ago, Center Rock Inc., was contacted by Malcolm Drilling due to low production with conventional rock augers and core buckets on a job site for the Highway 56 and 15 Connector in San Diego, CA. Center Rock sprang into action and manufactured a series of tools ranging in size from 48 to 96 inches for foundation drilling on this project.
For many years, Center Rock Inc. has been the leader in the manufacture and application of the multi-hammer canister drill (LP Drill). From its use in the 2010 Chilean Mine Rescue, when 33 miners were rescued through the 26” (66cm) hole drilled by a Center Rock LP, to horizontal push-pull applications, the Center Rock LP drills in any inclination from vertical to horizontal for mine rescue, burn holes, utility and ventilation shafts.
CANISTER-DRILLING FRICTION PILES FOR NAIROBI’S TALLEST TOWERS
Nairobi, Kenya, will be getting a new skyline soon. The Pinnacle Towers will truly tower over all other buildings in the city, and claim the title of Africa’s tallest building. The development is a complex that consists of two high-rise buildings: a 984′ (300 m) tall, 66-story office tower and 659.5′ (201 m) tall, 40-story Hilton hotel with a retail podium over four floors of car parking. When it’s completed, Pinnacle Towers will be nearly twice the height of Nairobi’s second tallest building, the UAP Tower at 531.5′ (162 m).
