Case Study: Project delays in Lawrenceville, GA Water Main Installation
Stuck In the Face of Hard Rock: The ROCKWYRM Air Hammer Gets the Job Done
In a growing suburb of Atlanta, a residential development project hit unexpected rock when attempting to install a 16” steel casing for a water main beneath the highway. After two contractors passed on the job, an auger bore was attempted, progressing only 8-10” after two days. With the deadline looming, Hardrock HDDP was called in to find a solution.
As specialists in rock drilling with years of experience in the field, they know that having the right tooling for the job makes all the difference.
Lamar Businelle, General Manager of Hardrock HDDP, brings 21 years of experience drilling in hard rock conditions. “To get the job done, we drilled a 6 inch pilot hole with a ROCKWYRM HDD60, covering 120 feet in two days of drill time. Hardrock used a custom-built roller cone reamer; each pass enlarging the hole until 24 inches was reached. Drill time on that project was nine days.”
After successfully completing the bore, they passed the baton to Metro Horizontal Boring to push the casing through with the auger bore machine. The team completed the project a day ahead of schedule!
