Active Landslide? Failing Slope?
The Ground Won't
Wait. Neither Do We.
When a slope fails or a road closes, the question isn't whether we can drill it — it's whether we can drill it faster than the ground is moving. Multiple drill units, 24/7 shifts when the schedule demands it.

Solutions
From horizontal drains to advanced drilling and grouting, JDC covers the full spectrum of geotechnical drilling challenges across transportation, mining, rail, and pipeline infrastructure. If the ground is your problem, we have the rig for it.
All Solutions →Projects
Every job is different — different geology, different access, different budget realities. See how we anchored a floating sewer in 50 feet of water, installed 587,000+ feet of drains over a decade in Oregon, and tied back an active landslide on Interstate 94.

Site Assessment
DOTs, primes, and asset owners bring JDC in when a site needs drilling expertise the average contractor doesn’t carry in-house — active landslides, deep dewatering, difficult access.
Engineering & Design
Dewatering systems and drain layouts are designed by licensed hydrologists on staff, matched to the site’s geology and access constraints.
Mobilization & Drilling
Multiple drill units and 24/7 work shifts when the schedule requires it — proprietary equipment built for difficult-access sites.
Project Completion
We stay on site through commissioning — electrical, discharge piping, and operations training handed off complete.
